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

Great batteries all around

Molicel might not be flashy like the Hohm rewrap batteries or even the efest. But they can’t be beat when it comes to all around performance. Mooch proves it. Molicel doesn’t lie about their battery ratings unlike some of the other brands out there, who lie and lie BIG. It’s fascinating how they can get away with it. That just makes me appreciate the Molicels and Samsungs and Sonys even more. And at these prices?? I was a FOOL for buying some Hohm batteries on a vape site. Live and you learn!

Great batteries, better price!

The new 21700's are great and last all day long in my Aegis Max. The prices are unbeatable anywhere online, and they are shipped quickly arriving just a few days later. In addition to the battery case that comes with all battery orders from Li-Ion Wholesale I also received (for the second time in a row) a free flashlight that takes a single18650 to 21700 battery and has SOS + strobe flash modes. I can't say enough about how awesome this company is with their extensive battery testing procedures and ability to keep very popular batteries in stock. The site is full of great information about lithium batteries and all of the precautions and safety measures you should take to ensure your batteries remain safe to use for a long time. This is the only place I get lithium batteries from because there isn't another store that offers as much as they do for even close to the prices they have. Thanks for both flashlights; you guys rule!

Expected more from all the hype

This is my first pair of Molicel batteries and I have to say I expected a much better cell. Neither cell made it to their minimum rated capacity and that was with only a 500mA discharge current, but one cell did make it to 4010mAh, which is ok, but still below minimum rating. I'll stick with Samsung 40T's.
