Cell phone Battery Types - The four most common types of batteries for cellular phones are:

• Lithium Polymer (Li-Poly)
• Lithium Ion (Li-Ion)
• Nickel Metal Hydride (NiMH)
• Nickel Cadmium (NiCad)
  
  

  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抯 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. Their trouble free service, longer running times and reasonable price has made Nickel Metal Hydride the most popular battery type for cellphones. Additionally, NiMH batteries are made from non-toxic materials and are environmentally friendly. CellularAccessory.com carries a complete and extensive line of Nickel Metal Hydride batteries.
  

  Nickel Cadmium (NiCad) batteries are of older technology and suffer from "memory effect". They must be completely discharged before recharging or damage can occur. This discharge procedure can add extra time to the overall charging process. The memory effect that is inherent in all NiCad batteries reduces the battery's overall capacity, run time, and life span. NiCad batteries are slowly being phased out and replaced by NiMH as the battery of choice by cellphone manufacturers and mobile professionals. Also, the "nickel cadmium" used in NiCad batteries is highly toxic to the environment. Please dispose of NiCad batteries properly.
