If a replacement battery is being used for the first time or

if the battery has not been used for a prolonged period, it

may be necessary to connect the charger, then disconnect

and reconnect it to begin charging the battery.
Unplug the charger from the electrical plug and the device

when not in use. Do not leave a fully charged battery

connected to a charger, since overcharging may shorten its

lifetime. If left unused, a fully charged battery will lose its

charge over time.
If the battery is completely discharged, it may take several

minutes before the charging indicator appears on the

display or before any calls can be made.
Use the battery only for its intended purpose. Never use

any charger or battery that is damaged.
Do not short-circuit the battery. Accidental short-circuiting

can occur when a metallic object such as a coin, clip, or pen

causes direct connection of the positive (+) and negative

(-) terminals of the battery. (These look like metal strips on

the battery.) This might happen, 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 device

with a hot or cold battery may not work temporarily, even
