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 manufacturer rated for 20A continuous current, versus many of the Chinese batteries with higher amp ratings.

The HG2 has been the industry standard for 3000mAh batteries for a few years now, and 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.  Fakes have been bad for many years, but they continue to get worse as demand continues to grow and the the genuine battery price goes up.

As always we've done extensive testing to be sure our stock is genuine so you can be confident you'll get real authentic LG HG2 from us.  We had a third party check our batteries as well, here are Mooch's LiionWholesale HG2 test results.

UPDATE 1/10/18: The well respected, independent third party battery tester, Mooch, has done an HG2 retest and his results are available here. Findings are consistent with previous HG2 tests.

Battery Warning

Warning: Lithium ion batteries may explode or burn due to improper use. Using these batteries for purposes not intended by the manufacturer, including outside a battery pack and/or without a BMS, may cause severe injury and damage. We are not responsible for any injuries caused by lithium ion batteries - use at your own risk.

All rechargeable batteries have inherent risks under any circumstance. Use caution with working with li-ion batteries (lithium-ion), LiPo (lithium ion polymer), and any rechargeable cells (together "rechargeable batteries"), as they have dangerous charging characteristics and are known to explode or burn if mishandled. A purchaser and user of rechargeable batteries should educate themselves on rechargeable batteries, especially as to charging, discharging, assembly, and storage. Learn more about proper storage and care for rechargeable batteries here. We are not responsible for any damage caused by the misuse or mishandling of rechargeable batteries.

Here are a few tips:

  • Never completely discharge batteries (below 2.5V under load or 3V unloaded)
  • Charge fully (to 4.2V) before first use
  • Never charge batteries to 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 your battery, only store in a case or individual box in a cool and dry place at approximately 3.6-3.7V
  • 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
  • Never exceed the battery's specifications
  • Never try to charge or discharge li-ion batteries with battery chargers that are not made for li-ion batteries
  • Always charge these batteries on and within fireproof material
  • Never leave rechargeable batteries in a recharging station unattended
  • Do not use any rechargeable battery or charger if any visible damage is present, or if known mishandling, accidental or otherwise, has occurred
  • Always store and transport rechargeable cells in a safe, non-conductive container (never keep a spare battery loose in a pocket, purse, etc. and always use protective cases)
  • Properly dispose of all battery cells and chargers in accordance with local laws and mandates (if you're unsure, contact your local municipality)
  • If a rechargeable battery overheats, hisses, or bulges, immediately quarantine the battery from any combustible materials - ideally, take the battery outside
  • If a rechargeable battery catches fire, the FAA recommends pouring water or soda on the battery and surrounding areas - ideally, use a foam extinguisher to quell the fire

Shipping issue

It's been more than 2 weeks and I still did not receive the item. Maybe the issue is with USPS but it looks the item is lost.

  • What device/application do you use this with? Vaping on a VooPoo A1 with CSMNT rda built to around 0.3 ohm.

Genuine product and decent shipping time.

They're HG2s....! I mean what more can I say? I'm glad Liion takes the extra time and effort to ensure genuine products. These are a perfect balance of amp rating and capacity for my needs.

Bought a set of Lg HG2 batteries

Overall a pretty good battery. I also bought a set of Sony VTC5A batteries and they Sony batteries do last a quite of a bit longer in the way I'm using them. Lg HG2's are still a solid battery though. I am taking a star off for not including free battery wraps like the company advertised on their page since I'm going to have to buy battery wraps now due to being a first time buyer. Also another star taken off because I had a code to get a free leather battery case and that was not included in my order either. If Liion will make this right and send me the battery wraps and leather battery case, I will change my review and stars. I hope that you make this right Liion. Thank you.
