the battery reaches a full charge. Leaving
devices on a charger too long can cause
them to overheat and can reduce battery
life.
2. PICK THE RIGHT CHARGER.
Only use the charger and cable that came
with your device. If no charer was supplied
or using your own charger, always follow
the manufacturer’s recommend charger
requirements. Take special care to match
the correct voltage and amp values your
device requires when picking a charger.
Chargers are designed for specic battery
types; mixing chargers and batteries could
result in unexpected problems.

ENVIRONMENTS.
Do not recharge your devices in environ-
ments where extreme temperatures can
occur. On particularly hot days do not
charge in places such as the inside of a
car, or an unairconditioned room. If it’s
