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.

    Great Batteries

    These typically last me a couple years or more of every day use. Also appreciate the fast shipping and great service from LIION Wholesale as well.

    3 Months Now

    I've been using three of these batteries for 3 months now. I generally use one per day occasionally some charge from a second - on long days. Im using a Kangertech Topbox Mini and the Toptank Mini with various SSOCC coils (clapton, .5 NC and sometimes Ni200) and sometimes the RBA plus. Using temp control the batteries dont last as long but thats due to the functioning of Topbox mini operation. When using wattage mode each battery will last two fills of my tank. I always refill when the level reaches the top of wicking holes in SSOCC. I charge using a XTAR VC4 and the batteries always take 2050 to 2100mAh. Im very happy with the performance. The batteries have at least 30 to 40 cycles with no problems. I rated four stars as of now if everything keeps working for expected life of battery ill come back and give five.

    First time buyer at LIION Wholesale... Very smooth experience... Battery's are as stated... Super price... Fast Shipping... These batt's run my Joyetech EVIV VTC Mini at 20watts with a Kanger Nano loaded with a 0.5 Clapton coil for well over 260 puffs. No problem charging them with the Xtar VP2... They charge fine at a 1amp charge rate if you need them quicker too... Will definitely be back here again when I need more batt's...
