Protected Panasonic NCR18650B 3400mAh 5A 18650 Button Top Battery - Wholesale Discount

Liion Wholesale

  • $ 5.99

SKU: panasonicNCR18650b_PCBb

This is a CLEARANCE product. No additional quantity discounts will be given. All sales will be considered final. Quantities ordered will not count towards quantity discounts on other products.


This 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 Seiko 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, and this is a BUTTON TOP style battery.  If you're 15W or lower and can fit a protected/button top battery then this can work.

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

Hi John - I apologize you're not happy with the USPS method you selected. I see from your order that you selected our economy shipping method, USPS Parcel Select. This can take anywhere from 1-4 weeks to arrive, as is disclosed in our cart during checkout. If you do not want to wait that long for your order, we suggest going with one of our more express methods, such as UPS, in the future.

  • What device/application do you use this with? Portable lasers.

My first experience buying from liion.

Absolutely excellent products and prices. I checked my new batteries for internal resistance and capacity. They are great. My only gripe would be shipping costs. But, that could be necessary to ship inside the US.
