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.

Advantages and Limitations of NiCd Batteries?
Advantages and Limitations of NiCd Batteries?
Fast and simple charge — even after prolonged storage.
High number of charge/discharge cycles — if properly maintained, the NiCd provides over 1000 charge/discharge cycles.
Good load performance — the NiCd allows recharging at low temperatures.
Long shelf life – in any state-of-charge.
Simple storage and transportation — most airfreight companies accept the NiCd without special conditions.
Good low temperature performance.
Forgiving if abused — the NiCd is one of the most rugged rechargeable batteries.
Economically priced — the NiCd is the lowest cost battery in terms of cost per cycle.
Available in a wide range of sizes and performance options — most NiCd cells are cylindrical.LimitationsRelatively low energy density — compared with newer systems.
Memory effect — the NiCd must periodically be exercised to prevent memory.
Environmentally unfriendly — the NiCd contains toxic metals. Some countries are limiting the use of the NiCd battery.
Has relatively high self-discharge — needs recharging after storage.

Title: Why You Should Be Using Rechargeable Batteries
|
|
When we ask ourselves why we should use rechargeable batteries, we are talking about rechargeable batteries of sizes AA, AAA, C, D and 9V. These rechargeable batteries offer many benefits and are intended for everyday use just like the disposable or primary alkaline batteries everyone uses.
An 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 reduction over their useful life. As an example, you can easily find 4 quality 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 (if you include the initial charger cost ). If you recharge these rechargeable batteries a minimum of 100 times, that means that these rechargeable batteries cost less than 10 cents per use.
Yes, 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, new technology 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 use cost for these additional rechargeable batteries drops to less than 4 cents per use ( you already have the charger ! ). Thirdly, electricity costs are very small considering some of the best 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 high grade 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 marketing hype 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 alkaline 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.

There are many appliances which use the mains or various types of batteries. You will find that some of these appliances will work better with a particular type of battery. There are also batteries which bear the names of well known brands like that of Panasonic batteries. When you're going to buy the batteries that you want there are different sizes which can be used. The items which can be powered by Panasonic batteries include calculators, notebooks, walkmans, Discmans, radios, torches and even lamps. Even though the batteries for these appliances vary in size there is one similarity that is constant. This constant is that you need ensure that you are only using new batteries when the time to replace these batteries comes around. The reason not to mix the various Panasonic batteries is the possibility of leaks occurring from the casing of the batteries. You will be able to find some Panasonic batteries which are geared towards high powered products. With the many different batteries that can be bought it is important that you choose the batteries which will provide you with the power that you need. You will need to decide how many batteries you want to buy at one time. This simply means that you can buy your Panasonic batteries in groups of two, four, or higher battery groups. There are some times when you will be lucky enough to find a box of batteries which are sold in lacks of 12. These batteries are excellent if you are going somewhere and you know that you will need to have an energy supply on hand. This means that if you are going to use Panasonic batteries for devices like a Discman or portable radio you will need to look into buying the right amount of high powered batteries. There is one interesting item that you will note when you are looking into buying your new Panasonic batteries. This item is simply the quantity amounts that you can find. One of the new inventions that you will find on some battery brands feature the ability to see just how much of power is remaining. To this end you will find a small colored band on one end of the battery. This band will lose it coloring as the power in the Panasonic batteries runs out of power. You will find the Panasonic batteries that you need in supermarkets and other retail stores. Muna wa Wanjiru is a Web Administrator and Has Been Researching and Reporting on Batteries for Years.

There are many different batteries which are great for appliances. These batteries provide lots of power to the appliance that you need. When you are looking at which battery to use you will find that D batteries are perfect for products like torches and radios. You can test the battery performance of these batteries before you buy them in order to know if you have a battery that is in excellent condition. By seeing to this matter early you will know if you need to buy more D batteries in another brand. This is a good idea as you avoid having to have more batteries than you need. You will be able to find the various D batteries that you want in any retail shop which sells batteries. You will have to do some research to find which of the D batteries are made to last for longer periods of time. You will find advertisements and claims from various companies which will help you to select the D sized battery that you require. When you look at these differences you will have a better chance of judging which batteries are better for the appliance that you are planning to use it for. In most cases the packaging on the D batteries will let you see which appliances will work best with these batteries. Sometimes you will also get to see rechargeable size D batteries too. This however is rare as the average D batteries are larger and thicker than your usual AA batteries. Now even though you will find it difficult to buy rechargeable batteries for the D class battery range the good news is that these batteries can last for quite a long time. For the most part D batteries are sold in packs of 2. There are times when you will be able to buy packs of 4 or even 8 batteries. You will however need to look for these multiple battery packs in a variety of places. The general stores where you can find D batteries are in supermarkets, drug stores, camera shops, the internet and lots of other places. You will have to be careful when you are choosing your D batteries as with all batteries these batteries have a certain shelf life. If you happen to buy a battery that seems to have run out quickly the chances are that you have somehow gotten hold of an old battery. To prevent this from happening you will need to select your D batteries from about the middle of the stack. You will then have a well working appliance with an excellent chance of lasting for a long time. Muna wa Wanjiru is a Web Administrator and Has Been Researching and Reporting on Batteries for Years.

Title: Do you know Replacement rates of NiCd batteries(1)?
|
|
Do you know Replacement rates of NiCd batteries(1)? Do you know Replacement rates of NiCd batteries(1)? Based on the successful reconditioning results, the Dutch Army now assigns the battery maintenance duty to individual battalions. The program calls for a service once every two months. Under this regime, the Army reports reduced battery failure and prolonged service life. The performance of each battery is known at any time and any under-performing battery is removed before it causes a problem. NiCd batteries remain the preferred chemistry for mobile communications, both in civil and defense applications. The main reason for its continued use is dependable and enduring service under difficult conditions. Other chemistries have been tested and found problematic in long-term use. During the later part of the 1990s, the US Army switched from mainly non-rechargeable to the NiMH battery. The choice of chemistry was based on the benefit of higher energy densities as compared to NiCd. The army soon discovered that the NiMH did not live up to the expected cycle life. Their reasoning, however, is that the 100 cycles attained from a NiMH pack is still more economical than using a non-rechargeable equivalent. The army’s focus is now on the Li-ion Polymer, a system that is more predictable than NiMH and requires little or no maintenance. The aging issue will likely cause some logistic concerns, especially if long-term storage is required. more info: www.good-battery.co.uk

Title: Rechargeable Batteries For Your RC Car
|
|
An RC car is run and operated by batteries. RC car batteries are important parts because basically, your electronic RC car will not run if it doesn't have batteries in it. On the other hand, even if it has batteries in it, it should be the correct batteries. There are in fact a lot of checking and testing first before you put it to use for your RC car.
RC cars and trucks that runs electronically need to be the rechargeable ones to compensate for the running hours of your practice and competition duration. Since there are so many types of batteries out in the market, you need to make sure that you have the correct information regarding the needed battery device for your RC car. So, first of all, know that rechargeable batteries are the NiCD and NiMH ones. NiCD stands for nickel-cadmium while NiMH is for nickel-hydride. Other than the two, it is not rechargeable so be very careful with this detail.
The brand that you prefer comes next because there are affordable rechargeable batteries on sale but ones which do not meet the needed requirement for running RC cars and trucks. Regardless though, make sure that you choose a battery brand that conforms well to your RC car/truck's running time needs.
The battery charger that you use also counts and lengthens the life of a rechargeable battery. Make sure that you select a good charger that automatically stops from charging when the battery is already full.
A battery pack has a specific voltage (V), power consumption (W) and Maximum Current Drain (A) limit and so it is also important for you to know these things. Take for instance the required volts of a battery to run a RC car is 7.2. This is already good for running a car for about 10 minutes but then, there are also conditions which affects the running time of a RC car.
Batteries are usually sold by packs, each pack consisting at least six or more batteries. The difference between the two NiCD and NiMH is the shelf life of each. A NiCD can last up to six months where as a NiMH battery can last up to 12 months. Regardless, keeping your RC car in its most top condition and making sure that you drive it with extra care helps your batteries perform at its best.

Title: Understanding Laptop Batteries
|
|
Types of Laptop Batteries: Nickel Cadmium (NiCd) Batteries: These were the first rechargeable batteries manufactured for laptops. They were relatively inexpensive, had high output and versatile, because they could be used in a wide variety of products. However, NiCd batteries have now been abandoned by laptop manufacturers with the introduction of more efficient and lighter-weight batteries. Nickel Metal Hydride (NiMH) Batteries: NiMH was a big improvement concerning power output, reliability, cost, safety and capacity. The "memory effect" was the only issue with NiMH batteries which require them to be fully discharged before recharging to gain maximum output. These batteries can still be found in older model laptops. Lithium Ion (LiON): This type of batteries has become the most popular for laptops since the “memory effect” has been eliminated, and much lighter than the other two in weight. However, the market price is also the highest. Battery Cycle: One battery cycle is used every time a battery is charged or discharged. Technically speaking, it is defined as the number of cycles a battery can perform before its nominal capacity falls below 80% of its initial rated capacity. Lifetimes of 500 to 1200 cycles are typical. For example, NiCad battery has a cycle life of 500-1000 or more cycles. Battery Run-Time: Battery run-time depends on a number of factors. Most of the time, it is the design of, and the power demands made by the machine that determines the actual battery run-time. For example, use of the screen, the hard drive and other accessories will significantly influence the duration of the run-time. What are Smart and Dumb Laptop Batteries: Some laptop batteries are equipped with internal microprocessor circuits that help manage battery energy, set the charger to the correct charge algorithm, predict running time, or according to Smart Battery System (SBS) forum, provide a state-of-charge (SoC) indication. These batteries are called “Smart” batteries. Those batteries termed as, “dumb” do not have these features, may be just counterparts, or may function to provide power only. Optimizing Laptop Batteries: 1. “Condition” is a term for fully charging and discharging a new laptop battery to maximize performance and allow it to reach its maximum rated capacity. NiMH and NiCd batteries need to be conditioned at least once a month to reduce the “memory effect”. 2. Metal connecters should be cleaned occasionally to maintain good conductivity 3. Ensure that device's power management features in the BIOS and Operating System are optimized, turning off the screen, using speed step 4. Avoid leaving your laptop on overnight all the time while charging. The laptop should be turned off occasionally. 5. Store the battery in a cool, dry, clean place if you’re not going to use it for a month or longer. 6. Turn down the brightness of the LCD screen when watching a movie on our laptop. Decrypt DVD movies and store it on your hard disk drive to avoid constant use of the DVD drive which consumes a lot of power 7. Never expose your laptop battery to heat, moisture, short-circuit, drop or physically abuse it.

Title: Why Rechargeable Batteries are Better Than Conventional Batteries?
|
|
The rechargeable battery offer many advantages to the user in comparison to conventional batteries. It can provide an opportunity to save money and time wasted in purchasing a new set of batteries every tine you run out of stock. Rechargeable batteries are convenient to use and are also recyclable. When we discuss about the rechargeable batteries, different sizes of batteries come in consideration. They are available in AA, AAA, C, D and 9V sizes intended to use in every day life like other alkaline batteries.
Rechargeable batteries can be used again and again by putting them on charger when they are down of charge. The quality of rechargeable battery can be explained in simple way by measuring the storage capacity of electricity in the battery, its ability to deliver the stored electricity when needed and the ability in maintaining its energy level when it remained unused. There are many manufacturers claiming the superior performance of their batteries and at low prices.
Rechargeable batteries are also called as cheap batteries as they save money in purchasing the new one every time when it goes low. Another added advantage of rechargeable batteries is that they are more environment friendly in comparison to throwaway primary batteries. They are not regularly thrown in the garbage like other lead acid batteries. Though the conventional batteries are also recycled by the companies but the energy spent in entire production of new battery like from mining to manufacturing, shipping, use and disposal could be saved in rechargeable batteries. Therefore, it can be said that if you are using a rechargeable battery, 100 or more disposable conventional batteries could be saved from increasing the garbage.
The selection of the battery could be made on the chargeable rounds it can last. There are batteries that can be recharged up to 200, 300, 400 and 500 rounds. You can further divide the cost of batteries used in a span of time and the number of disposable batteries it reduce from garbage. So, using a rechargeable battery could prove to be a better option then the conventional battery in terms of saving money and environment.
