cell phones now use a lithium-ion (li-ion) battery. This is because the
batteries are smaller, lighter and hold a longer charge than other
battery types. Although your cell phone is capable of charging its own
battery, you may be able to charge other batteries with the equipment.
As long as it is another lithium-ion battery and you have an
appropriate adapter, you can perform the charge yourself.
Things You'll Need:
Cell phone charger
the current lithium-ion battery from your cell phone. On one side of
the phone it states the voltage. When charging another battery, you
want it to have a similar voltage; otherwise, the mobile phone is
unable to charge the equipment.
an adapter designed for your cell phone and the desired battery. Many
of these adapters fit several different battery sizes
Slide the lithium-ion battery into the adapter, and then connect the adapter to your mobile phone.
the phone charger into the mobile phone's power port. Plug it into a
local outlet. The phone now charges the lithium-ion battery.
How to Correctly Charge a Cell Phone Battery
phones are powered by battery packs. The most common types of battery
packs for cell phone are rechargeable NiMH, NiCD and Li-Ion battery
packs. When a cell phone battery is new, it should be conditioned three
times. Conditioning the battery ensures the full cell capacity of the
battery is being utilized. After the battery has been initially
conditioned, the battery can be charged using a charger for as little
or as long as desired.
the charging cord into the charging port. The charging port is
typically located on the side or bottom of a cell phone and may be a
circular or USB charging port.
the charging cord into an energy source. Depending on the type of cord,
this power source could be an electrical outlet, 9 volt cigarette
lighter or a USB port.
the battery to fully charge. Look at the charging indicator light to
ensure the phone is charging. Most phones will beep or display a
message when the battery is charged. Remove the charging cord from the
the phone in the same manner you normally would. Do not charge the
phone until the battery is almost dead. Locate the battery power
indicator in the right hand corner of the cell phone. When the battery
is fully charged, the indicator icon will be full. When the battery is
half full, the battery icon will indicate this. When the battery
indicator indicates the battery is less than a quarter of the way
charged, recharge the phone until it is fully charged. Complete this
process a total of three times.
Charging A Conditioned Cell Phone
Plug the charger into the cell phone. Plug the charger into a power source.
Allow the charger to charge the battery for any desired amount of time.
Remove the charger once the battery is charged to the desired level.
