heat, cracking or igniting the battery.
Note: Lithium-ion batteries are unstable (potentially dangerous) at extremely low and high
temperatures
Charging temperature range: 0°C to 45°. Charging temperatures outside this range may
cause the battery to become hot or cracked, or probably damage the battery's
performance and reduce the expected battery life.
When the charger is normally charged, the charger is red, and when the charger is green,
the battery is sufficient.

Improper use of batteries will cause the batteries to heat, crack and even burn, which
causes severe damage.
Must follow safety rules as below:
Do not throw batteries to fire or high-heat stuff.
Do not reversely place the negative and positive polarities.
Do not use metal things like wires to connect the positive and negative polarities.
Do not mix or store batteries with hairpin, necklace or other metal stuff.

batteries to heat, crack and burn. If batteries are used improperly like that, it will reduce
the durability of the equipment and damage of performance.
Except professionals, do not use any equipment to dismantle batteries
If original batteries are used on other devices, battery life will be damaged and reduced. If
the device causes abnormal current, it will cause batteries to overheat, crack and burn,
thus causing serious damage.
