Battery safety is very important.  Mistreated batteries can get extremely hot and/or vent which could cause injury.  Always follow the following rules to make sure this doesn't happen.  We are not liable for mistreated batteries.

 

Never completely discharge batteries (below 2.5V under load or 3V unloaded).

Charge fully (to 4.2V) before first use.

Never use a lot of force on the battery to install

Use only high quality battery chargers.

Do not expose to heat.

Do not connect the positive contact to the negative contact without an appropriate load.  

Be mindful of the current limits in the specification and never exceed them.

Never keep a spare battery loose in a pocket, purse, etc.  Always use protective cases for loose batteries.  If it shorts against a piece of metal it can be very dangerous.

Never charge battery 4.3V or above.

Do not charge unattended.
