    • 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.
