  • Saved My Bore Scope from the Garbage
My bore scope camera battery wouldn't charge. I took it apart and found this battery on Amazon that was the same size. Thank you for saving me $120 on buying a new one.

  • a HIGH QUALITY LITHIUM ION BATTERY
The voltage is within specification, the battery holds a charge that meets specification, the battery discharges and recharges properly. The product is absolutely, perfectly satisfactory. I doubt that I will ever come close to discharging and recharging anywhere close to the number of specified cycles. ... show more

  • BMPRO RV Control Panel Battery
The battery in the picture is the bad one out of my RV BMPRO Tablet Panel. I bought this new Amazon battery and it works. I carefully disconnected the wires out of the white male plug. I cut the wire on the old battery leaving plenty of wire, because there's no matching female plug. Clean the ends of the wires and mash them in the wire looms of the new one. Tape them and reassemble the BMPRO tablet. IT WORKS GREAT 👍There is a YouTube instruction video but no need to solder if you do it the way I instructed. I cleared the coated wires using a lighter because it is very tiny. ... show more

  • Connector wired backwards for my application. Capacity optimistic.
Like others I purchased this battery for a Arduino MKR WiFi 1010. Thankfully, I've read the other reviews and was able to pull the pins and reverse the connector. I also charged it fully, and ran it on an 1A constant current source load. Measured Capacity 1822mA hr.
