    WARNING! General Battery Safety

    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.

    • Download "Safety of Lithium-Ion Batteries" document
    • 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.
