batteries

This is important as some products need an exceptionally charged battery for the products to work. An example of this is that of car batteries. You will need to have your car battery working in find condition if you are expecting to get anywhere. To help you see if the battery is working in top condition you can buy a tool that allows you to gauge the strength of the battery.

These tools are also excellent if you need o see if a certain battery will work with other appliances. There are other needs that you can use also. These are battery testers. These items are also good ford judging the battery performance too as they will show you in terms of numbers just how a battery works well.

You will have to do some research in order to find the best device which will show you the battery performance. When you look at these differences it should become clear which ones are better. You will also get to see what other features these tools have.

When you are thinking about buying a tool which will allow you to test the battery performance it is best if you do some shopping first. As there are many different batteries that you can look at, it is best if you have an idea about the functions you will need in a battery tester.

As with many of the products which are in the market today you will need to choose the one that will provide you with accurate information. You will need to make sure that no matter what tester you are looking into buying, you will be able to read the information which is provided about the battery performance.

While having a tester can make life easier, it is best if you have the necessary implements close at hand. This will make judging of the battery performance an easy task. Additionally with the knowledge which is given about battery performance you will know when the time arrives to replace your battery. This is a knowledge base article i am writing on batteries and different kind of batteries continue next week.

Batteries are unique components that are comprised of various elements that include heavy metals such as nickel cadmium, mercury nickel metal hydrate and alkaline that can harm the environment if not properly recycled. It is extremely important that each of us understands how to properly dispose of all of those batteries that we use everyday in our lives. In 2006 the state of California actually imposed a landfill ban on all household batteries. It's vitally important that you understand how your local community may require you to dispose of your batteries that are no longer working. Some states or municipalities that have recycling programs will require you to sort batteries by type [lithium, alkaline and rechargeable for example] in order to make the recycling effort more efficient. Be sure to understand what is required of you.

In general terms, if your local area does not have any recycling facilities then you may find that local stores such as an automotive outlet will offer to accept your old batteries for recycling. Some places of laws that old car batteries have to be accepted by automotive outlets when you buy a new one. But if you do have to dispose of batteries in a landfill or the garbage, keep one thing in mind. Despite the fact your batteries may not have enough power left to run your iPod or your child's toy truck, if several batteries are clumped together they can emit enough of a charge to cause them to ignite. It's better to be safe than sorry. You should also take note that you should never use a new battery with old ones as they can also work together ignite, leak or rupture and ruin the electronic item.

One of the things you can do to reduce the number of batteries that need to be disposed of is to use rechargeable batteries. Rechargeable nickel cadmium batteries today can simply reduce the number of batteries that you need per year. You still need to dispose of these rechargeable batteries properly as well but the more we use rechargeables the less likely we are to simply cast off normal everyday batteries in an improper way because we have so many of them.

In the United States alone, consumer households buy more than 3 billion batteries each year. That's about 10 batteries per person in America alone. Obviously there is an important need for each of us to continue to be conscious of the need to dispose of batteries properly to protect the environment. Continue to do your part and we can help each other. Buy your batteries/ target=_new>Texas Instruments battery today at our online shopping mall.

But interestingly enough, many hybrid car owners actually would like the ability to plug in their vehicles at night. This way, they can use that much less gasoline; the gas engine part of the hybrid would now need to run that much less when they made their morning commutes. Now, nothing's free--including household electricity. However, the idea here is that the additional charges on their monthly electric bill would still be far less than the added $3.00+ per each additional gallon of fuel. The 2008 and beyond hybrid electric vehicles are supposedly going to have the capability to plug them in.

Another popular myth is that the batteries only last a couple years at the most. Then you've gotta buy thousands of dollars worth of new batteries. This is far from true:

The standard warranty on hybrid batteries usually runs between 80,000 and 100,000 miles. Great advances in battery technology since 2000 have raised the life expectancy to a respectable level in 2007. Taxi services using hybrid-only cars are springing up everywhere...now THAT should raise the eyebrows of hybrid naysayers. The warranty for battery life may be at 100,000 miles, however, taxi services are seeing 200,000 to 300,000 miles with absolutely no degradation in battery performance. And we're talking several large taxi fleets in New York City!

If the batteries DO need replacing, they will cost between $1700 - $3000, not $10,000+ like many folks say.

But the key to this long battery life lies in "smart charging" where the electronic charging computer will not let the battery get charged above around 60% of capacity, nor let it drop below 40% of its capacity. This allows the new NIMH (Nickel Metal Hydride) batteries to run practically forever.

That being said, battery technology remains the main area for the greatest advances in hybrid car technology yet to come. Lighter batteries that hold longer charges and put out higher power is the dream of every hybrid engineering company. Battery technology is where hybrids stand to gain the most benefit.

The main hope for improving this situation for hybrid cars lies with lithium batteries. These are the same batteries that are currently used to power laptops and cameras. They provide a much more concentrated and therefore smaller way of storing energy as electricity. While lithium batteries are the best option for batteries in hybrids now, they aren't without problems...

The problem with lithium batteries is making them big enough so that they can store enough energy to power hybrid cars without having to revert to the gas engine when driving in town. Lithium batteries are very efficient when manufactured to a certain capacity and size. But if this is increased they are subject to a condition called thermal run off. This can cause larger batteries to overheat and in some instances they can actually catch fire! (You've noticed how hot laptop computer batteries can get.)

The main problem is the cobalt, a metal used in the manufacture of lithium batteries. Many manufacturers have been working on a solution to this problem. The most promising solution seems to be replacing the cobalt with phosphate. This produces a much safer and more reliable battery. There is some power loss as opposed to using cobalt only, but the batteries should still be a long way ahead of conventional lead-acid and NiMH batteries now used in hybrid cars. C. Brown is the author of http://Hybrid-Electric-Car.net where you can learn more about hybrid car batteries on his website.

DELL battery tips:

• Before you use your new DELL battery for the first time you must charge them fully. Please note that for new rechargeable DELL notebook batteries, it is often necessary to cycle them at least three to five times or more before they reach peak performance and capacity. The first several times that you use your batteries DELL , you may find that they run down (discharge) quickly during use. Not to worry, this is normal until the batteries actually form up. No memory effect. Chargeable even if it has not been used up yet.
• It is important to condition (fully discharge and then fully charge) the DELL laptop battery every two to three weeks. Failure to do so may significantly shorten the laptop battery's life (this does not apply to Li-Ion batteries, which do not require conditioning). To discharge, simply run the device under the DELL battery's power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in the user's manual.
• If the battery.co.uk/laptop-batteries/dell.htm#>DELL battery will not be in use for a month or longer, it is recommended that it be removed from the device and stored in a cool, dry, clean place.

There are many intricacies to trouble free rv'ing

but it is our deep cycle batteries that lie at

the at the heart of "rv maintenance" confusion...

and only for one reason.

We think we understand our deep cycle batteries

when the fact of the matter is..we don't!!!

The confusion is easily understood however if you

just stop and think about it. The bulk of our

experience with lead acid batteries is with our

automobiles SLI (starting, lights, ignition)

battery. Our deep cycle battery is a lead acid

battery also and looks just like our automobiles

starting battery, but the similarities end there.

The batteries are not only very different

internally but most of the rv'ers problems with

deep cycle batteries revolve around how often

they are used and how they are maintained.

Generally our automobiles are used on a more

routine basis and are charged with a very

adequate charging system. Such is not always the

case with rv's.

Sporadic use coupled with inadequate charging

systems leads to problems, problems which can be

overcome...only however if they are recognized

and understood. This is where an understanding of

deep cycle batteries will pay dividends both in

battery efficiency and reliability. The

following statements and replies should help

clarify some common fallacies about the use and

maintenance of deep cycle batteries.

#1. The lead acid battery is one of the greatest

inventions of the 29th century.

False! Believe it or not the lead acid battery

goes back 147 years to 1859.

#2. A RV/Marine battery is a true deep cycle

battery.

False! A RV/Marine is a

cross between a true deep cycle battery and an

automobile battery and is not a true deep cycle

battery.

#3. Deep Cycle batteries are fine as long as they

read 12 volts.

False! Deep Cycle battery reading

12 volts is 75 of battery

failures.

#4. Is it ok to take a voltage reading

immediately after charging?

False Surface charge should

always be removed prior to taking a voltage

reading.

#5. The best time to take a voltage reading is

during charging.

False! Voltage readings taken while

charging are not accurate.

#6. The correct time to take a voltage reading on

deep cycle battery is 12 hours after charging.

True! Waiting 12 hours after charging to take

a voltage reading is the "correct" way to check a

battery.

#7. Its ok to let deep cycle batteries sit

between uses.

False! Deep cycle batteries are

chemically "alive". They should be either

charging or

discharging. If not.... they are dying!!!

8# Charging a deep cycle battery at l4 volts will

ruin it.

False! A deep cycle battery must reach

l4 volts in the bulk charging stage or it will

not reach 100% charge.

#9. Its ok to have deep cycle batteries on a "

maintenance charge" between uses. True

! See answer #7. Inactivity is the reason for

deep cycle battery failure, inefficiencies, and

poor capacity. Deep cycle battery owners who do

not understand this will experience premature

loss of capacity and and battery failure.

If you find yourself with no electrical adapter or power source and need your battery to operate for as long as possible, here are a few tips you can try when your notebook computer is in battery mode:

Use the notebook?? power management system In Microsoft Windows the ??ower Options?power management application can be found inside the Control Panel. In the Power Options Properties tab select the ??ortable/Laptop?power scheme. Many IBM notebook manufactories also provide their own custom power management applications, which help to optimize power usage and extend Lenovo Notebook battery time.

Turn down the display brightness You can lower the LCD brightness level to use less energy. In fact a lower brightness level also strains the eyes less and causes less fatigue.

Close any unused applications Applications are a burden on the system and require energy to run. Closing any unused applications will reduce that burden and any energy consumption down the line.

Remove any unused PC Cards or USB devices from your IBM notebook These devices require energy even when they sit idle, so removing them can help to extend your Lenovo notebook?? battery time. Disable Wireless LAN or Bluetooth network adapter when not in use Ditto for the Wireless LAN or Bluetooth network adapters. Increase system memory Your computer stores data for use by the CPU in system memory or as virtual memory in the hard drive. Increasing system memory helps to reduce the system?? reliance on the hard drive, which uses more energy than system memory. Reduce unnecessary optical drive operation/activity Avoid activities that require your optical drive to operate constantly, such as listening to CDs. Avoid graphics intensive applications The Lenovo notebook system will run in a high performance settings when using these applications,causing the battery to run down at a very quick rate.

Batteries are designed to help you. They store energy for your use; they allow you to start and work machines, they help you get where you’re going. Yet batteries need help to continue to function properly.

What is a battery?

A battery is a device that stores electricity through chemical changes of the materials inside of it.

How do you use a battery to produce an electric current?

Basically there are two plates, one plus and one minus, with a chemical solution between them. When you charge the battery, you put electrons into the battery through the negative terminal and take them out through the positive terminal. That causes a chemical reaction which stores the electricity.

When you use or discharge the battery, you draw the electrons from the battery through the negative terminal and put them into the battery through the positive terminal. That causes a chemical reaction which frees up the electrons that were stored earlier.

The positive pole has a shortage of electrons; the negative pole has a surplus of electrons. The electrons flow from negative to positive. That is what produces the current.

What makes a battery slow down, become weak and die?

The chemical reaction which stores electricity in the battery involves creating lead sulfate from lead or lead oxide, and sulfuric acid. Conversely, storage of the electricity (when the battery is charged) converts lead sulfate to lead oxide or lead. These reactions are reversible.

There is one tragic flaw! Lead can combine with sulfate in two different ways. The first, discussed above, is beneficial. The second way forms a crystal which does not conduct electricity and cannot be converted back to lead or lead oxide. It forms a layer on the plates which blocks the beneficial reaction from taking place. As more area is covered with this lead sulfate crystal, the battery loses power.

How does usual battery maintenance help batteries?

Usual battery maintenance consists of

* Keeping the battery clean. This removes electrical shorts on top of the battery. * Putting water in the battery to replace water that evaporates during charging and discharging. * Charging the battery after every use. This prevents to some extent the second kind of sulfate from forming.

Even if the above is done, what does usual battery maintenance fail to do?

It fails to dissolve or prevent lead sulfate crystals. They actually build up while the battery sits on the store shelf. In fact, few have ever experienced a completely “new” battery. No amount of charging and no voltage, no matter how high, will remove the second type of lead sulfate.

What can be done to help this problem?

Use Battery Life Saver, an electronic device that employs a square wave (a powerful, variable wave) to excite the crystals and cause them to dissolve. With Battery Life Saver, your battery will not slow down or die because of lead sulfate. Chuck Van Breemen invented it with the user in mind. Just attach Battery Life Saver to the battery or battery bank. It will prevent lead sulfate from forming. It can also be used to renew dead, sulfate ridden batteries. Save the cost of buying new batteries!

What color does your crew prefer on the job site? Do your guys prefer yellow and black tools by DeWalt or maybe the blue of Bosch or Makita? Perhaps the red of Milwaukee tools, the grey of Porter Cable, or the black of Skil? What ever color your team uses, they have one thing in common; they have to get the job done. And to get any job done, you need power.

Power for tools comes in two main types; corded and cordless. There are benefits and drawbacks to each. Corded tools will work for as long as there is a connection to a generator or power grid. Their limitation is the length and size of your power cord and standing water on site. This can be overcome with a GFCI built into a power cord and a thicker wire such as a 12 gauge wire.

Cordless tools use batteries to provide power as long as they last. These power tool batteries have gotten to be as powerful as a corded tool. With the advent of multiple battery chargers, cordless power can be used on any jobsite. One of the best chargers around is by DeWalt and includes a radio for job site entertainment. Batteries can have a major drawback in that they can stop holding a charge for various reasons. These reasons include a memory charge buildup, a set number of charging cycles, and heat sensitivity. A battery memory charge buildup occurs on older Nickel Cadmium batteries that have not been completely discharged before recharging. The new Lithium ion batteries do not get this memory buildup as quickly and tend to wear out due to age or charging cycles. And when a battery will no longer charge, make sure to recycle it properly so it doesn’t contaminate the environment.

Generators provide good power for a jobsite where a connection to the power grid is unavailable. Generators do have drawbacks in that they may surge due to power requirements from different simultaneous users and the maximum rated load of the generator. Knowing the power demands of your tools will help you to determine what size generator you need. Remember, just because there is an open outlet doesn’t mean there is sufficient power. Generators also require regular maintenance and care and it may be wise to look at porter cable generator parts. Keeping a log for all your tools will help you to prevent damage and ensure many productive hours.

No matter what the color of your tools, make sure you choose one that will meet your power needs. Your jobsite and type of work will determine your needs. Don’t forget that power is an integral part of your business success as down time can cost you serious money. The right parts and tools will save you money as you make money. Careful planning can help prevent injuries and keep your crew productive.

How lithium-ion batteries?

How lithium-ion batteries?
In spite of its great popularity, the cobalt-based lithium-ion has some limitations. It is not very robust and cannot take a high charge and discharge currents. Trying to force a rapid charge or loading the battery with excess discharge current would overheat the pack and its safety would be jeopardized. The safety circuit of the cobalt-based battery is typically limited to a charge and discharge rate of about 1C. This means that a 2400mAh 18650 cell can only be charged and discharged with a maximum current of 2.4A. Another drawback of the cobalt system is the increase of the internal resistance that occurs with cycling and aging. After 2-3 years of use, the pack often becomes unserviceable due to a high voltage drop under load that is caused by elevated internal resistance. This condition cannot be reversed.
New cathode material opened the door for higher rate capability. Moving away form cobalt also helped in lowering manufacturing costs. In 1996, scientists succeeded in using lithium manganese oxide as a cathode material. This substance forms a three-dimensional spinel structure that provides improved ion flow on the electrode. High ion flow reflects in a lower internal resistance and hence higher loading capability. Unlike the cobalt-based lithium-ion, the resistance stays low with cycling and aging. The battery does age, however, and the overall service life is similar to that of the cobalt system. A further advantage of spinel is its inherent high stability. Spinel needs less in terms of safety circuit compared to the cobalt system.

Do you know NiCd batteries ?

Do you know NiCd batteries affected by 'memory'?In the past, the purpose of battery analyzers was to restore NiCd batteries affected by 'memory'. With today's nickel-free batteries, memory is no longer a problem and the modern battery analyzer assumes duties other than conditioning weak batteries. In an environment with nickel-free batteries, the purpose of an analyzer is shifting to performance verification, quality control, quick testing and quick priming.
Common sense suggests that a new battery should always perform flawlessly. Yet even brand new batteries do not always meet manufacturer's specifications. With a battery analyzer, all incoming batteries can be checked as part of a quality control procedure and a warranty claim can be made if the capacity drops below the specified level toward the end of the warranty period.

They come packed and super charged with power and allow you to run everything from the simplest contraptions to the most complex instantly. More and more these days people around the world are choosing solar powered battery operated cars to drive and are amazed with the power they produce. Yes, I would have to say batteries/>batteries play a huge part in our everyday lives and will for a very long time.

Probably the most familiar batteries to everyone are the dry cell batteries such as AA's, AAA's, C's, and D's that are used in flashlights, remote controls, clocks, lights, games and toys. The most common are alkaline batteries and they claim to have a longer life.

There are several types of batteries for electronic devices and cordless tools. The first that comes to mind is a lithium-ion battery. While they may not deliver a better run time than the NiMH battery, the lithium-ion battery will deliver better total performance over the life of the battery than NiCad and NiMH batteries. Most cell phone batteries are Lithium Ion (LiOn)— the most lightweight rechargeable battery kind that does not have an effect on memory.

Lithium Ion (Li-Ion) batteries/>batteries have the capacity of the NiMH battery, With ZERO memory effect and zero toxins. Another added bonus is the fact that Li-Ion batteries weigh half as much as NiMH batteries.

NiCad (Nickel Cadium) batteries are hardly ever seen anymore, they proved to have low capacities and heavy metals that harmed the environment. In addition they had the dreaded "memory effect". Which meant if they were recharged before they were completely drained of power the longevity (Memory Effect) of the battery was compromised.

NiMH (Nickel Metal Hybrid) batteries/>batteries have up to twice the capacity of the NiCad batteries and only half susceptible to the memory effect. The NiMH batteries are also becoming rare.

There are a few reasons a battery may fail these include but are not limited to:

* A faulty cell design * Battery abuse * Manufactured improperly * Operated in uncontrolled conditions * Batteries lose power or degrade overtime

There are many place in the world that are still very remote and without electricity, many of these people depend on the use of batteries/>batteries to complete daily activities. While batteries may be common place for most here in the United States, they play a very important part in making life bearable for many people.

Be sure to read all product brochures or guides for compatibility requirements before using batteries of any type. Batteries should be handles and stored properly. manufacturers warn against exposing batteries to extreme heat or over charging. Batteries are composed of combustible chemicals and should be handled as such. Also remember there are proper ways to dispose of batteries/>batteries so not to contaminate land fills.

How can batteries be connected?
Note: When interconnecting batteries

(cells), they must be identical in voltage and amp rating!
Batteries may be connected in series. The

positive terminal of the first battery is connected to the negative terminal of the second

battery; the positive terminal of the second is connected to the negative of the third,

and so on. The voltage of the assembled battery is the sum of the individual batteries.

The batteries are connected: + to - to + to - to

+ to -, etc. The capacity of the battery is

unchanged.
Batteries may also be connected in parallel. The positive terminal of the first battery is

connected to the positive terminal of the second battery, the positive terminal of the second is

connected to the positive of the third; the negative terminal of the first battery is

connected to the negative terminal of the second battery, the negative terminal of the

second is connected to the negative of the third and so on. The batteries are connected: +

to + to + and - to - to -. In this configuration, the capacity is the sum of the

individual batteries and voltage is unchanged.
For example, (5) 6V 10AH batteries connected in series produces a battery array that is 30 Volts and 10AH. Connecting

the batteries in parallel produces a battery array that is 6 Volts and 50AH. Ordinary auto

batteries are designed in the same fashion. Six 2-volt cells are arranged in series to

produce a 12v battery. Many Ni-Cd batteries are

arranged in the same way.

One of the oldest batteries used in laptops is the NiCad, nothing but the Nickel Cadmium, which is very rarely used today. These Nickel Cadmium or the NiCad batteries is very heavier when compared to laptop batteries which are used to day. These NiCad batteries are prone to memory effect and they aren’t environment friendly as it contains heavy metals. Now battery manufactures have stopped manufacturing batteries of this type. The Nickel Metal Hydride or NiMH batteries are less likely to be prone to memory effects, but produces better power when compared to NiCad batteries. However most companies have stopped manufacturing NiMH batteries also.

The Lithium Ion or Li-Ion batteries is the most commonly used batteries used today in Laptops and also in other digital gadgets as Lithium Ion or Li-Ion batteries are compatible, provides excellent power and lesser in weight. Li-Ion batteries are very much useful in smaller and lighter devices such as digital cameras, mobile phones and of course in laptops. Another biggest advantage of Lithium Ion batteries is that they do not suffer memory effect at all! However these batteries tend to lose its charge quickly towards the end of their life span. If this happens, then this is an indication, that the battery needs to be replaced.

Here is useful information on laptop batteries; Laptop batteries are rated by "V" which means voltage and "mAh" which stands for Milliamp-hours. Voltage is the rate of energy or power drawn from the battery into the laptop. The Milliamp-hours shows the run time of the battery. Therefore if the battery has higher mAh / Milliamp-hours, then it means the battery will run for a longer time. Batteries having different mAh / Milliamp-hours can be used for laptops but you need to make sue that the voltage rating is the same. You need to cross check with your laptop manual or you older laptop battery to make sure that voltage rating is the same. In case if you’re using batteries of different voltage, then it can cause very serious damage to your laptop.

Here are some useful tips to ensure optimal battery life: Use the AC adapter whenever possible, try lowering the brightness settings on the screen backlight. Set the Windows Power Management settings to maximum savings. Try turning off Autosave features and disable auto Insert Notification on the CD-ROM. Also disconnect any unused devices such as modems when not in use. Put you’re laptop to Hibernate or Suspend feature when you are taking a break.

One advantage of rechargeable batteries is that they can be recharged and reused hundreds of times and the really goodones greatly outperform the everyday leading brand throwaway alkaline batteries.

Rechargeable batteries can be used over and over again which produces an incredible cost saving over their useful life. As an example, we can easily purchase 4 good AA rechargeable batteries that come with a smart charger for $30 to $40 US. For such a package deal, each AA rechargeable battery costs $10 US (including the initial charger cost ). If we reuse these rechargeable batteries a minimum of 100 times, that means that these rechargeable batteries cost less than 10 cents per use.

There are many factors not accounted for in our cost analysis, but if all these other factors were included, they would only further reduce the total per use cost well below 10 cents per use. Firstly, recently developed rechargeable batteries can easily provide 30% to 50% more energy than regular alkaline disposable batteries. Secondly, if you buy 4 more rechargeable batteries at $16 US or less, your per recharge cycle cost for these supplementary rechargeable batteries drops to less than 4 cents per use ( you already have the charger ! ). Thirdly, electricity costs are minimal considering top AA rechargeable batteries will deliver 3 Watt hours or more and electricity from the grid will cost you 6 to 10 cents per 1000 Watts per hour. Fourthly, a quality rechargeable battery may not last 1000 uses but will certainly last a lot more than 100 uses.

Another often mentioned positive reason for using rechargeable batteries is that they are considered to be more environmentally friendly than the throwaway alkaline batteries. There are pros and cons to this argument and the general practices of society and private enterprise are not really based on helping the environment. So far, helping the environment is all lip service and studies show that recycling is only an economic initiative. Over 90% of lead acid batteries are recycled (the rechargeable car battery for example) because of the economic costs of lead. This is far from the case for other rechargeable battery technology.

Dumping rechargeable batteries in with regular garbage is no better than dumping disposable alkaline batteries or any battery for that matter. Environmental friendliness has to account for the entire product life from mining to manufacturing, shipping, use and disposal. One thing is for sure, for every rechargeable battery you use, 100 or more disposable alkaline batteries are not going to the landfill.

If a quality rechargeable battery lasts 200, 300, 400 or 500 cycles, you can further divide the cost examples we just talked about by 2, 3, 4 or 5. This also applies to the number of disposable batteries that can be eliminated from the pollution factor.

Rechargeable batteries like NiMH (Nickel Metal Hydride) rechargeable batteries have proven that they can deliver greater performance in our ever demanding digital devices. Combined with the fact that they cost much less on a per use basis than disposable alkaline primary batteries and that less mass ends up in the landfill, leaves only one question.

Why are you not using rechargeable batteries instead of disposable one time use batteries? Do you question the performance or value of rechargeable battery technology? Have you been disappointed in the past when using rechargeable battery technology? Is convenience more important than saving money or helping the environment?

Whatever the reason is, we would like to know. If you are thinking about using rechargeable batteries, there are resources that can help you. G.
