This product is either priced at a low wholesale-level price or is a limited quantity product so it is not eligible for any quantity discounts. Quantities ordered will not count towards quantity discounts on other products.

The LiionWholesale 1S1PNCR18500A is a PCB protected version of the Panasonic NCR18500A, with wire leads and a connector so that you can connect it to any device or snip off the connector and put on your own connector of choice.  This is a 2040mAh 4A battery and is a great small size battery.  

OEM replacements

This product is commonly used in some off the shelf electronics by various companies.  If you have opened your product and found our "UR18500 Battery Pack" or our 1S1PNCR18500A, then this product can be used to replace it.  UR18500 Battery Pack is the old version of this battery, this new one is backwards compatible but will provide longer battery life.

High Level of Safety Certifications

This product has a very high level of safety certifications including  UL 62133, UN38.3/DOT Testing, IEC 62133, CE, REACH, and RoHS.  Most batteries on the market do not have nearly this level of documented safety.

All protected batteries are not the same

These are manufactured with a very high quality PCB including a Japanese Ricoh protection IC with two MOSFETs.   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 Panasonic.  Our company then adds the high quality PCB along with the wire leads in an ISO certified factory to all safety standards.  A blue wrap is put over the top to hold it together.

Compatible with 3.7V

Some companies market batteries like this as 3.7V, this will replace any 3.7V lithium ion with no issue.  3.7V vs 3.6V is just a labeling difference and is not an actual voltage difference inside the battery.

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 (usually below 2.5V for li-ion or 2.0V for LiFePO4, check datasheet)
  • Charge fully (usually to 4.2V for lithium ion or 3.6V for LiFePO4) before first use
  • Never charge batteries to more than their full charge voltage
  • 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 for a long time, only store in a case or individual box in a cool and dry place at approximately 3.5-3.7V for li-ion or 3.2V for LiFePO4
  • 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

Far better than OEM

I used this to replace the battery in a NiteRider bicycle light. This battery charges faster and holds more charge than the OEM battery of the same size. It was easy to clip the wires and connect it to the factory leads.

  • What device/application do you use this with? NiteRider Lumina Micro 650 Front Bike Light
