NiCD
This type of battery is the first generation. Large capacity, this battery is suitable for old phones that powerful. According to the size and capacity, the charging process was repeated quite a hassle. For example, replenishment should be done at the time power is completely depleted. Because NiCd batteries have a memory effect, the longer its capacity will decrease if the filling is not empty properly.
NiMh
The next generation is NiMH. These rechargeable batteries still have a memory effect but only temporarily. So it is more flexible than NiCd types. To recharge not have to wait is completely discharged, but the consequences will be felt quickly exhausted.
Li-Ion ( Lithium Ion )
Than the two previous generations, this type no longer has a memory effect. So you can fill in repeated without waiting for the battery runs out. Li-Ion batteries have a shorter life cycle. Even if the redundant dicas lithium ion battery will lose its ability, rather than NiCd or NiMH.
Li-Po ( Lithium Polymer )
This newest generation of rechargeable batteries. In addition to eco-friendly, its superiority over Li-Ion battery. For treatment of Lithium Polymer batteries, not much different from the Lithium Ion. However, Handling should be extra careful. Given the nature of liquid with a loud enough pressure could cause the battery to change shape.
Li-Po weakness it requires us to recharge the battery not to wait for the phone turns itself off. Or as much as possible when the phone is low battery warning. If not, the phone will be hard to be enabled because the battery is not fully recovered.
