Cell Phone Batteries & Nokia Cellular Battery
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.
