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.
When the operating time (talk time and standby time) is noticeably shorter than
normal, it is time to replace a new one.
Please stop using the charger and battery when they are damaged or show
evidence of aging.
Return the wear-out battery to the provider or dispose of it in accordance with
environment regulations. Do not dispose of it in household rubbish.
Warning: If the battery is damaged, keep away from the discharge. If the leakage does
come into contact the eyes or skin, please wash thoroughly in clean water and consult
with a doctor.
