As always, you can trust Liion Wholesale to have tested random samples from each and every batch to make sure all the batteries are fresh and genuine.  Anyway we have an agreement with Efest themselves and buy only manufacturer direct for these so the chances of issues are small, but we test anyway.  You won't get that with most suppliers.


Warranty:  Satisfaction guaranteed, if your battery is DOA or you think there's a problem with it just let us know within 14 days of your order and we'll make it right.

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.

    These batteries work fine and have held up well so far. I'll have to return after some use to give a more accurate review, but they seem to be better than the HE4's that I was using.
