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.
  • 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.

    Samsung INR18650-30Q 15A 3000mAh battery

    These batteries were perfect for my application. They were well marked and sized to specs. They replaced Samsung 15A 1600mAh batteries, and the addition capacity was welcomed in my application.
