There is a newer version of this product.

We suggest you consider Protected LG MJ1 3500mAh 10A 18650 Button Top Battery - Wholesale Discount as an alternative.

Note this is the old version of this product.  It comes in a clear wrap, and is a little bit on the large side and doesn't fit in all devices.  This is the rest of our inventory of this, then they'll be gone.  If you would like our new version, click here:  LiionWholesale Protected 3500mAh MJ1

Please note: There may be some blurring on the label. The label is for shipping purposes only and can be removed. This does not affect the cell.

The new LG INR18650MJ1 3500 mAh is a really new 18650 battery cell that can handle fairly high drain applications (10A) while offering a massive 3500mAh.  It's one of the best batteries we offer for high discharge flashlights or other devices that need a high capacity but medium discharge protected battery.  The protected NCR18650GA is its only real competitor and is a good alternate choice as well.  

These are manufactured with a very high quality PCB.   This protection circuit protects the battery from mishandling, overcharge, or overdischarge while allowing the battery to do its job properly.

The cell is made by LG Chem in Korea.  Our company then adds the high quality PCB along with the button top in an ISO certified factory. A clear wrap is added for another layer of protection.

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

  • What device/application do you use this with? Braun Magnetic Slim Bar Folding Rechargeable LED Light
Bought these cells to upgrade

Bought these cells to upgrade the ones in my Harbor Freight Braun LED magnetic flashlights. With the original, cheap battery (claimed 2200mAh), the light would die after about 30 minutes. Now it lasts over an hour - very nice low cost upgrade that's been really useful when working on my car.

protected 18650 batteries

they are very good batteries and the price was reasonable. I was quite surprised with the free gift! I needed batteries with longevity between charges.

Top Quality Batteries and Company

Top shelf quality and performance at realistic affordable pricing. For a first time buyer from Liion Wholesale... Karma was in my favor when I accidentally stumbled onto the site. The end user price can not be beat and these protected batteries are just what super high output flashlights need. They do great in battery packs series or parallel as well. Oh... and processing and shipping of the order was really fast too. Questions to customer service are answered conscientiously quick

  • What device/application do you use this with? I am using these in a nitecore hc60 headlamp, a nitecore hc50 headlamp and a mh25 gt flashlight
Very good batteries

I have used the batteries several times although I haven’t had them long. They seem to be strong and long lasting from what I can tell. The price is very good and the quality seems to be also. I expect to do more business with this company in the future and so far I am very pleased. The ordering process, shipping time and quality were all excellent.

  • What device/application do you use this with? CREE XML-T6 (2c cell flashlight)

Your batteries will not fit into my flashlights because the black wrapper overlaps itself thus causing a ****. Additionally 2 of them don't want to take a full charge.
