This section provides information about the phone’s batteries, accessories,

change as the batteries, chargers, and accessories change.
This phone is intended for use when supplied with power from the
ACP-7U (standard travel charger), the ACP-8U (rapid travel charger) or
the LCH-9 (rapid cigarette lighter charger). Other usage could invalidate
any approval given to this apparatus and might be dangerous.
Warning! When you purchase batteries, chargers, and
accessories for your phone, use only batteries, chargers, and
accessories that have received approval from the phone’s
manufacturer. The use of any other type of phone-related
hardware will invalidate any approval or warranty applying to the
phone and could also be dangerous. For availability of approved
batteries, chargers, and accessories, check with your dealer.
• The battery charge indicator will show you when the battery is fully
charged.
• When you are not using a charger, disconnect it from the power source.
Do not leave the battery connected to a charger for more than a week,
since overcharging could shorten its lifespan.
• If left unused, a fully charged battery will discharge itself over time.
Temperature extremes can affect the ability of your battery to charge.
Therefore, allow it to cool down or warm up before trying to charge it.
