SAFETY

Try to keep batteries in a temperature between 41°F (5°C) and 95°F (35°C).

If the battery is stored in temperatures above or below the recommended range, give it time to warm up or cool down before using.

Completely drain the battery before recharging. It may take one to four days to completely drain.

Store the discharged battery in a cool, dark, and dry place.

Purchase a new battery when its operating time gradually decreases after fully charging.

Properly dispose of the battery according to local regulations.

DON’Ts

Don’t attempt to disassemble the battery – it is a sealed unit with no serviceable parts.

Don’t expose the battery terminals to any other metal object (e.g., by carrying it in your pocket or purse with other metallic objects such as coins, clips and pens). This can short circuit and critically damage the battery.

Don’t leave the battery in hot or cold temps. Otherwise, it could significantly reduce the capacity and lifetime of the battery.

Don’t dispose of the battery into a fire.

If you find the battery charger heating, smelling unusually, or smoking, disconnect the battery charger from the AC outlet, turn your device off, and remove the battery from your phone immediately.

It is normal the battery charger becomes warm while charging the battery.
