5 18650 Battery
JT on Dec 8th 2021
Recently I received a battery operated clipper that would not hold a charge and ran way too slow. I turned to Battery Kings for a solution and the 18650 battery they sent is top quality. It is amazing how a good battery can bring new life to a your devices.

5 Different battery
Thomas on May 26th 2021
Battery King told me that the Ultrafire 18650 4000mah battery was out of stock and offered a different battery of the same size and shape. They shopped the new batteries right away and when I got them they were the same physical size, but the mah rating was 5000 vs the original 4000. I got an upgrade and they work great.
