Battery Safety Basics

Do not overcharge or over-discharge.

To combat this, do not leave your batteries in any charger without supervision.

Make sure that you are able to see or check on the charger.

Remove from the charger when fully charged.

Leaving batteries in a charger all night long or longer can cause them to be overcharged, which can result in battery failure.

Charging your battery over 4.25 volts can shorten its life-cycle and going over 4.5 volts can cause it to burst.

Recharge batteries with a resting voltage below 3.6V as soon as possible.

Leaving Lion batteries in a discharged state will incur irreversible damage – creating a loss in capacity and a loss in cycles.

Do not let your batteries touch each other or other metallic items, like carrying it in your pocket with keys and coins.

Use battery cases to transport and store batteries safely.

Do not use batteries with damaged wraps or without the insulators.

Do not dispose of batteries in a fire.
