Battery Use
 Do not store battery in hot areas or throw it into fire. Otherwise,
it will cause explosion.
 Do not disassemble or refit the battery. Otherwise, it will cause
liquid leakage, overheating, explosion and ignition of the battery.
 Please store the battery in a cool dry place if you don't use it for a
long period.
 The battery can be recharged for hundreds of times, but it will
eventually wear out. W hen the operating time (talk time and
standby time) is noticeably shorter than normal, it is time to
replace it with a new one.
 Please stop using the charger and battery when they are
damaged or show evidence of aging.
