This LiionWholesale Protected Panasonic NCR18650B is perfect for a light or other device needing a button top and lots of mAh capacity, for a cheaper price than the Efest version while not losing quality.  We also carry the unprotected flat top NCR18650B for people building battery packs.

The cell is made by Panasonic.  Our company then adds the very high quality Ricoh PCB along with the button top in an ISO certified factory to all safety standards.  A clear wrap is put over the top to hold it together while still showing the Panasonic wrap underneath.

Note we do not recommend this battery for most e-cigarette applications, the protection limits the cell to ~15W.  If you're 15W or lower and can fit a protected battery, then this will work well.

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

Thank you

Great price, great product, only took a few days to arrive with basic shipping. They even added a freebie flashlight that’s pretty nice. Couldn’t be happier.

  • What device/application do you use this with? Too large dia for Felix PD32 flashlights so I use them in cheaper flashlights
Diameter is too large

The diameter of your 3400 mAh model 18650 is so large that it is a tight press fit in my 3 expensive Felix PD32 flashlights. If I were to force your batteries all the way into my PD32s, they would be jammed in so tightly that I would have no way to remove them. Therefore, I am relegated to using your LIION batteries in my cheaper flashlights. Your batteries charged up exactly as they should, and work just fine in my cheaper flashlights. Dale
