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.
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.
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.
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.
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.
