The huge number of portable devices, you can find AAA batteries.On sale you can find battery types: nickel-metal hydride, lithium polymer, lithium-phosphate, nickel cadmium.But increasingly, battery manufacturers are taking as a basis for technologies that use nickel.It is possible to increase the specific capacity, while excluding the self-discharge.The great advantage of the lithium polymer batteries is the fact that they can be processed into any form, even several millimeters thick.This allows their use in electronic devices that are limited in size: cell phones, netbooks, watches, etc.The most common type is the applicable AAA batteries.
huge minus lithium polymer batteries is that they are not interchangeable.That is, if your device has a battery fails, it remains one option - to buy the same, and it is used for the same device as your.Yes, on the one hand, they are convenient, unique battery can be fabricated of any shape, but in the case of failure have to replace long search.You can not replace the battery, manufactured by the same company, the production of analogue competitor.So we have to look for the original, and the price is quite high.
standard AAA batteries - the perfect solution, they are used in the vast majority of electronic equipment.They are cheaper to manufacture, easily replaced, even on conventional batteries, are similar in size.However, as compared with similar batteries, they have a lower capacity, which affects the operation time of the device.For their charge using special chargers, powered by a conventional power grid.At AAA batteries, the price is low enough, and this contributed to their rapid spread.
Battery done by a variety of chemical transformations.Part of the incoming energy is spent on the charge for conversion of the chemical elements, and the other is dissipated as heat.This so-called efficiency of the battery and it will never be 100%.Due to the fact that a lot of energy is converted into heat, the battery does not charge the large currents would otherwise overheat and battery may simply explode.Producing AAA batteries, producers are trying to reduce the amount of heat energy released, it will allow the use of higher currents for charging and to significantly reduce the global cooldown battery.As you have seen, the rate of charge depends on the total amount of current.
AAA batteries require careful handling to him.They can not be subjected to low temperatures, which is detrimental impact on the battery capacity.High temperatures can bring the battery from the system, so you need to carefully monitor the temperature mode, which uses batteries.It is also harmful for them for a long stay in the discharged state, so if you decide to remove the NIMH-elements for storage, they should be charged.By following these simple tips, AAA battery will last you a long time.
