Cell
Phone Batteries Guide
Cell
Phone Batteries - The four most common types of batteries
for cellular phones and mobile handhelds are:
Lithium
Ion (Li-Ion) Lithium
Polymer (Li-Poly)
Nickel
Metal Hydride (NiMH) Nickel
Cadmium (NiCd)
Lithium
Ion Batteries (LiION) are the most popular cell phone batteries
available.
Li-ION have replaced NiMH batteries for many phones because they
provide 4 distinct advantages:
Li-ION batteries
provide 40% longer Standby and Talk Times than NiMH batteries.
Li-ION batteries are lighter and more compact than NiMH batteries.
Li-ION batteries does not suffer from memory effect .
Li-ION batteries will last over 30% longer than NiMH batteries because
the cells accept more charge cycles.
Li-ION batteries rank as the "best value" of all cellular
phone battery types.

Lithium
Polymer Battery(Li-Poly) is the newest and most advanced
technology for cellular phone batteries. This brand new chemistry
of battery allows for the most compact cells available. Li-Poly
batteries are extremely light and thin and allow the most battery
life for the size. Lithium Polymer cellular batteries share all
of the benefits of Li-ION batteries but will last over twice as
long.
Nickel
Metal Hydride Batteries (NiMH) were introduced in the early
1990's as an improvement over older chemistries like Nickel Cadmium
(NiCd). Although they may have a very slight memory effect, NiMH
batteries are much more reliable than previous chemistries. Compared
to a NiCd battery of equal size, a NiMH battery will run for 30-40%
longer on each charge. NiMH batteries can be recharged 60% in just
15 minutes using a car charger, an obvious asset for motorists.
The unique NiMH chemistry packs much more power than NiCd. Additionally,
NiMH batteries often have twice the lifespan of NiCds.
Nickel
Cadmium Batteries (NiCd) are manufactured using older technology
and suffer from memory effect. They must be completely discharged
before recharging to avoid incurring damage to the battery. This
discharge procedure can add extra time to the overall charging process.
The memory effect inherent in all NiCd batteries reduces the battery's
overall capacity, run time, and life span. NiCd batteries are being
slowly phased out and replaced by NiMH and LiION. Also, the "nickel
cadmium" used in NiCd batteries is highly toxic to the environment.
Thus, it is difficult to responsibly dispose of NiCd batteries.
Memory Effect - The term "memory" in
reference to batteries means the battery "remembers" its
usual discharge point and superficially "needs" a charge
whenever it hits that point. In other words, if you have a NiCad
that always gets discharged to only 50% of its capacity, it will
eventually not run below that 50% mark if you ever wanted to discharge
it to a lower point.
NiCd batteries
and their inherent memory effect generate many problems and customer
complaints. In most cases their charge-holding capacity greatly
declines or they burn out and die well in advance of their normal
life expectancy. For these reasons, merchants no longer sell NiCd
batteries or support NiCd technology. Instead, they offer NiMH and
LiION replacement batteries for existing NiCd models. Most exclusively
promote Nickel Metal Hydride, Lithium Ion and now Lithium Polymer
as the preferred cellphone battery technologies for mobile professionals.

Battery
Recycling
For proper disposal of your old battery, you should return it to
the original place of purchase or to a collection center. You can
also contact the local Department of Household Hazardous in your
state. Your local Town Hall is also a good place to inquire.

and Talk Times:

and Talk Time information page.
How
to maximize the life of your cell phone battery -- There
are several things you can do to maximize the useful life of your
battery: Dirty battery contacts are the number one source of charging
problems. Clean the battery contacts with alcohol and a cotton swab
from time to time. Make sure no cotton is left on the contact points.
Don’t leave your rechargeable batteries dormant for extended
periods. Take them for a "spin around the block" every
so often. Even if you use AC power most of the time; use the battery
periodically to keep it fresh and healthy. Unplug your AC adapter
if you are not using your cellphone. Batteries that sit idle for
extended periods of time without charging begin to lose their ability
to hold a charge and will self-discharge, so remember to charge
them again before use. Always store batteries in a cool, dry place
away from heat and metal objects.
Intitial
Charge Cycle -- New cell phone batteries must be trickle
charged (slow charged) prior to their first use and for the first
several uses. As all of our batteries are new, they are uncharged.
All batteries require a "break-in" period, so don't be
alarmed if your battery doesn't hold a full charge right away. A
new battery may show false full charge as indicated on your phone
or charger. Also the battery may not power up the phone because
of low voltage. For the First Three Cycles, please make sure to
charge the battery fully and drain it fully before recharging. This
will properly condition the battery and will ensure that it will
operate at its maximum capacity. This is recommended for all cellular
phone batteries. You can discharge most portable phones by
unplugging the AC adapter and leaving it turned on until completely
discharged. Remember - "Take care of your Cell Phone Battery
and your Phone Battery will take care of you."
Note: mAh –
stands for "milli Amp hours" and is the measurement of
a battery’s storage capacity.
