Lithium Polymer (Li-Poly) is the newest and most advanced technology for cellular phone batteries. Li-Poly is ultra-lightweight & does not explode, even when a nail is driven through it! Since the chemistry is enclosed in plastic pouches instead of a metal can, significant weight & form possibilities exist! Manufacturers will soon be molding this type of battery to fit the dead air spaces in some cell phone designs. Lithium Polymer shows all the same advantages of Lithium Ion without the weight or rigid form factors! Li-Poly does not suffer from memory effect, and will deliver up to 40% more battery capacity than the same size of NiMH battery.
Lithium Ion (Li-Ion) is an advanced technology for cellular phone batteries. Li-Ion does not suffer from memory effect and will deliver up to 40% more battery capacity than the same size of NiMH battery. Li-Ion batteries are slightly lighter than NiMH batteries and also have a longer battery cycle lifetime when compared to NiMH batteries. Unfortunately, Li-Ion batteries are more expensive and not available for older cell phone models. CellularAccessory.com carries a complete line of Lithium Ion batteries.
Nickel Metal Hydride (NiMH) batteries are relatively newer technology and also do not suffer from memory effect. Compared to a NiCad battery of equal size, a NiMH battery will run for 30-40% longer on each charge. Also important from a driver’s perspective, NiMH batteries can be 50% recharged in just 15 minutes, and up to 90% in 1 hour using a car charger. The unique NiMH chemistry enables the packing of twice as much energy into a given mass than is possible with NiCads. This can also result in NiMH batteries having up to twice the life span of NiCads. NiMH batteries rank as the "best value" of all cellular phone battery types.
