192 Section 4A: Important Safety Information
Battery Tips
Battery life depends on the network, signal strength,
temperature, features, and accessories you use.
ⅷ Always use Motorola Original batteries and
chargers. The warranty does not cover damage
caused by non-Motorola batteries and/or
chargers.
ⅷ New batteries or batteries stored for a long time
may take more time to charge.
ⅷ When charging your battery, keep it near room temperature.
ⅷ When storing your battery, keep it uncharged in a cool, dark,
dry place.
ⅷ Never expose batteries to temperatures below -10°C (14°F) or
above 45°C (113°F). Always take your phone with you when
you leave your vehicle.
ⅷ It is normal for batteries to gradually wear down and require
longer charging times. If you notice a change in your battery
life, it is probably time to purchase a new battery.
Contact your local recycling center for proper battery
disposal.
Warning: Never dispose of batteries in a fire because they may
explode.
