Cellular Phone Battery Type

Nickel Cadmium (NiCD)

The most popular type of rechargeable batteries used in the industry.

Maximum performance and power retention is optimized in NiCD batteries when the battery is properly "conditioned" throughout its life. Conditioning consists of completely discharging the power supply prior to recharging, and then charging to full capacity.

If the battery is frequently charged without first being fully discharged, or if the battery is often provided with less than a full charge, the batteries power reserve capacity can be temporarily diminished. This temporary capacity loss is commonly referred to as "memory effect."

To keep your NiCD batteries performing at peak levels, it is recommended that you condition your battery at least once a month. Many after market brand chargers offer a discharge option. Look for the term "Conditioning" before buying your next charger. Putting your battery through one complete discharge/charge cycle per month will remove any "memory effect" that may exist.

Nickel Metal Hydride (NiMH)

These batteries offer capacities up to 30% higher per charge than NiCd batteries of the same physical size.

Nickel Metal Hydride Battery products are less affected by "memory effect." However, long storage periods will result in a temporary discharge of power. Most manufacturers recommend "conditioning" at least once per month.

Lithium Ion (LION)

The newest rechargeable battery chemistry available. Lithium Ion is not affected by the 'Memory Effect'. It can deliver the same capacity and run time in a smaller, lighter pack. The chemistry is most popular in cellular and laptop products.

Lithium Ion batteries deliver more energy per unit (known as "energy density") than Nickel Metal Hydride (NiMH) or Nickel Cadmium (NiCD). In other words, used on the same phone, Lithium could deliver substantially more talk/standby time than NiMH or NiCD. In addition, Lithium batteries are generally lighter than NiMH or NiCD batteries of the same capacity.
