The LG HG2 (full part number INR18650-HG2 or LGDB1865), sometimes lovingly referred to as the LG Chocolate, is an amazing battery for people who need high capacity with high current output.  This battery is rated very conservatively and outperforms many of the Chinese batteries with much higher amp ratings.

Note many of the versions on the market have a new warning text on them, but we have a large stock of the LG HG2 with no warning so at this time this battery has no warning on it.

Because this battery is so in demand, there are many fakes on the market.  You can see more information in our post here:  Fake HG2 information.  

As always we've done extensive testing to be sure they're real so you can be confident you've got the real thing.  We had a third party check our batteries as well, here are Mooch's LiionWholesale HG2 test results.

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.

    Solid LG HG2

    Googled 18650 batteries, these guys came up, googled to see what others thought, pulled the trigger on a bunch of them. I couldn't be happier. They would flawlessly and have a great battery life.

    • What device/application do you use this with? Smok Alien 220w starter kit with Baby Beast tank.


    They last me about a day before recharging, longer than my He2's by quite a bit more than I expected. Perhaps the 3000mah rating is overly conservative. Li Ion Wholesale prices are the lowest around, shipping is terrific.
