In a huge number of portable devices, youyou can find AAA batteries. On sale you will find batteries of kinds: nickel-metal hydride, lithium-polymer, lithium-phosphate, nickel-cadmium. But more and more often manufacturers of accumulators take as a basis technologies that use nickel. This allowed increasing the specific capacity, eliminating the self-discharge. A huge advantage of lithium-polymer batteries is the fact that they can be made in any shape, even a few millimeters thick. This allows them to be used in electronic devices that are limited in size: cell phones, netbooks, watches, etc. The most commonly used type are AAA batteries.
A huge minus of lithium-polymer batteriesis that they are not interchangeable. That is, if in your device such a battery went out of order, then there is one option - to buy a similar one, and applied exactly for the same device as yours. Yes, on the one hand, they are convenient, you can make a unique battery of any shape, but if it breaks, you will have to look for a replacement for a long time. It is impossible to replace a battery produced by one company, an analog of the production of a competitor. Therefore, we will have to look for the original, and the price for them is quite high.
Standard AAA batteries are an excellent solution,they are used in the vast majority of electronic equipment. They are cheaper to manufacture, easily replaceable, even for ordinary batteries, which are similar in size. However, in comparison with similar batteries, they have a smaller capacity, which affects the operating time of the device. To charge them, special chargers are used, powered from the usual electrical network. On AAA batteries, the price is quite low, and this contributed to their rapid spread.
The battery is charged by variouschemical transformations. Part of the incoming energy for the charge is spent on the transformation of chemical elements, and the other is dissipated in the form of heat. This is the so-called efficiency of the battery charge and it will never be equal to 100%. Due to the fact that a lot of energy passes into heat, the batteries do not charge with high currents, otherwise there will be overheating and the battery may simply explode. By manufacturing AAA batteries, manufacturers are trying to reduce the amount of heat released, this will allow using higher currents to charge and significantly reduce the total battery recovery time. As you understand, the charging speed depends on the total current.
AAA batteries require carefultreatment. They should not be exposed to low temperatures, which adversely affect the capacity of the battery. High temperatures can disable the battery, so you need to carefully monitor the temperature mode in which the batteries are used. Also, it is harmful for them to be long in a discharged state, so if you decide to remove the NIMH-elements for storage, then they should be charged. Following these simple tips, AAA batteries will last you a long time.</ p>
