AA rechargeable batteries may have been known to the general public for quite some time but only a few knowwhat it really is. Thus, if you are trying to find the best rechargeable aa batteries in the market, it would be wise to educate yourself first on what it is. First of all, there are various kinds of rechargeable batteries and they can be classified according to their composition. If you heard about rechargeable Lithium aa batteries, this means that they are made from Lithium. Other materials that are used in rechargeable batteries are carbon zinc, zinc bromide, lead acid, alkaline and nickel combinations. A new innovative kind of rechargeable battery is composed of Lithium ion, which allowed the batteries to last twice as long as ordinary batteries. However, these are only a small fraction of the vast number of batteries that have been made, although consumers are very familiar with Lithium and alkaline batteries that have been the trademark of a number of big companies in recent years.
Important Terminologies Used in AA Rechargeable Batteries
- AA – This is the standard size in batteries, which is usually utilized in portable devices.
- mAH – This means milliampere-hours. It measures the amount of current that is produced by the battery, multiplied by the number of hours needed to produce the required energy. The higher the mAH, the longer is the duration of the battery.
- C – The overall capacity of the battery
- NiCD – Nickel Cadmium
- NiMH – Nickel Metal Hydride
- Li-Ion – Lithium Ion
Nature, Charging and Disposal of AA Rechargeable Batteries
Best AA rechargeable batteries are composed of more than a single cell. There is a secondary cell that can be recharge to almost full capacity by electricity conducted through a charging mechanism. However, you must consider a decaying factor when using rechargeable batteries. There is also an accumulator inside the battery that acts as the engine behind its rechargeable feature.
Some rechargeable batteries can be recharged over 3,000 times. The amount of time it will take to charge the battery depends on its capacity. To know how long it will take, get the capacity of the battery and divide it by the charger rate. To allow for some inefficiency, just add around twenty percent to the result. Remember that a partially charged battery requires less time for recharging.
When choosing a charger for AA rechargeable batteries, you will frequently encounter the terms fast charger and rapid charger. As mentioned previously, the capacity of the battery dictates its charging time. A charger that is capable of charging a standard nickel cadmium 180 mAH battery in one hour can take as long as eight hours to recharge a NiMH 1500 battery that has a higher capacity. It would be best to disregard such terms perform your own rough calculation.
When disposing AA rechargeable batteries, do not just throw them away as their chemical makeup makes them very dangerous to the environment. They should also not be disposed of in fire or extreme heat as they can release toxic chemicals that are harmful to man, animal and nature.
