Protecting your battery.
For best battery performance, you should follow these guidelines:
Use only SANYO-approved batteries (model numbers
SCP-02LBPS and SCP-02LBPL) and AC adapter, cigarette
lighter adapter, and desktop charger (model number
SCP-01ADT for AC adapter; model number SCP-02CLA for
cigarette lighter adapter; model number SCP-02DTC for
desktop charger). These chargers are designed to maximize
battery life. Using other batteries or chargers will invalidate
your warranty and may cause damage as well.
To avoid damage, charge the battery only in temperatures that
range from 32˚F to 104˚F (0˚C to 40˚C).
Do not use the battery charger in direct sunlight or in high
humidity areas, such as the bathroom.
Never dispose of the battery by incineration.
Keep the metal contacts at the bottom of the battery clean.
Do not attempt to disassemble or short-circuit the battery.
You may need to recharge the battery if it has not been used for
a long period of time.
