In a huge number of portable devices, you can find AAA batteries. On sale you will find batteries of the types: nickel metal hydride, lithium polymer, lithium phosphate, nickel cadmium. But increasingly, battery manufacturers are taking technologies that use nickel as the basis. This made it possible to increase the specific capacity, while eliminating 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 you to use them in electronic devices that are limited in size: cell phones, netbooks, watches, etc. The most commonly used type are AAA batteries.
A huge disadvantage of lithium polymer batteries is that they are not interchangeable. That is, if such a battery is out of order in your device, then there remains one option - to buy a similar one, moreover, it is used specifically 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 not possible to replace a battery manufactured by one company with an analogue of a competitor. Therefore, you will have to look for the original, and the price is rather high.
Standard AAA batteries are an excellent solution, they are used in the vast majority of electronic equipment. They are cheaper to manufacture, easy to replace, even with ordinary batteries, which are similar in size. However, compared with similar batteries, they have less capacity, which affects the operating time of the device. For their charging, special chargers are used, powered by a conventional electrical network. For AAA batteries, the price is quite low, and this contributed to their rapid spread.. , . 100 %. - , , , . , , . , .
AAA batteries require careful handling. They must not be exposed to low temperatures that adversely affect battery capacity. High temperatures can damage the battery, so you need to carefully monitor the temperature regime in which the batteries are used. Also, it is harmful for them to remain in a discharged state for a long time, therefore, 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.
