Tips and Recommendations

Battery safety is very important.  Mistreated batteries can get extremely hot and/or vent which could cause injury.  Below are rules that should always be followed when using any Li-ion (Lithium-ion), LiPo (Lithium-ion Polymer) or any rechargeable battery and/or charger to prevent potential injury.

– 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 a 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 batteries, 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.
– Do not mix and match old and new, used and unused batteries.
– Dispose of all battery cells and chargers in accordance to local laws and mandates.

Before purchasing any Li-ion (Lithium-ion), LiPo (Lithium-ion Polymer) or any rechargeable battery and/or charger, Heavenly Blue Vapor recommends the user to have technical knowledge on all aspects of safety and precautions for said batteries.  Please do your research on different amperages, charging, storing and using these types of batteries.  Use them at your own risk.
