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.

    Fantastic Capacity for an 18650

    This is probably the biggest capacity 18650 you can find on the market today. (2017) The only known competition to this cell is the LG MJ1 which has similar capacity. There has been a comprehensive review comparing the two where this Sanyo bested the LG. However, one of my concerns is that the cell of this light was not made in Japan like the Panasonics that came before it. I was assured that despite being made in China, these cells share the same quality as the Japanese-made ones but only time will tell. I have several old Panasonics which are over 10 years old, after testing them with a battery analyzer, they still have about 2400+ mAh capacity left after all this time and these are used quite heavily. I would recommend this battery to those looking for high-capacity cells to use in flashlights. For vapers, you may want to check out other cells as the discharge rate of this cell is quite low so not ideal for vaping.
