Nokia 8810 - Charging and Discharging the Battery

Charging and Discharging the Battery

• Your phone is powered by a rechargeable battery.
• Note that a new battery's full performance is achieved only after

two or three complete charge and discharge cycles!

• The battery can be charged and discharged hundreds of times but it

will eventually wear out. When the operating time (talk-time and
stand-by time) is noticeably shorter than normal, it is time to buy a
new battery.

• Use only batteries approved by the phone manufacturer and

recharge your battery only with the chargers approved by the
manufacturer.

• When a charger is not in use, disconnect it from the power source.

Do not leave the battery connected to a charger for longer than a
week, since overcharging may shorten its life. If left unused a fully
charged battery will discharge itself over time.

• For good operation times, discharge the NiMH battery from time to

time by leaving your phone switched on until it turns itself off. Do
not attempt to discharge the battery by any other means.

• Temperature extremes will affect the ability of your battery to

charge: allow it to cool down or warm up first.

• When the battery is running out of power and only few minutes of

talk time remain, a warning tone is heard and

Battery low

is

briefly displayed. When no more talk time is left,

Battery

empty

is displayed and a warning tone is sounded and the phone

switches itself off.

Using the Batteries

• Use the battery only for its intended purpose.
• Never use any charger or battery which is damaged or worn out.
• Do not short-circuit the battery. Accidental short-circuiting can

occur when a metallic object (coin, clip or pen) causes direct
connection of the + and - terminals of the battery (metal strips on
the back of the battery) for example when you carry a spare battery
in your pocket or purse. Short-circuiting the terminals may damage
the battery or the connecting object.

• Leaving the battery in hot or cold places, such as in a closed car in

summer or winter conditions, will reduce the capacity and lifetime
of the battery. Always try to keep the battery between 15 C and 25
C (59 F and 77 F). A phone with a hot or cold battery may
temporarily not work, even when the battery is fully charged. NiMH
batteries performance is particularly limited in temperatures below
-10

°C (14 F). Li-Ion batteries performance is particularly limited in

temperatures below -0 C (32 F).

• Do not dispose of batteries in a fire!

Batteries must be recycled or disposed of properly.

Must not be disposed of in municipal waste!
