• BATTERIES AND CHARGERS
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.
