Battery safety is very important.  Mistreated batteries can get extremely hot and/or vent which could cause injury.  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.

  • Do not store your li-ion batteries fully charged for an extended period of time (weeks or more)

  • If you must store battery then do it in a case or individual box in cool and dry place at approximately 3.6V - 3.7V.

  • Never try to charge or discharge li-ion batteries with battery chargers that are not made for Li-ion batteries.
