    Hey! They are batteries...they work fine. What is most important is that, the one I wanted was on back order so they actually emailed to ask if an alternative was OK! Heck yes! Thanks

    18650 Battery

    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.

    Needed a little help figuring some things out, but talked to someone personally (always nice) and now my batteries are ROCKING!

    Different battery

    Posted by 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.
