Battery fine...service better
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.

18650s should all be this good!
Needed a little help figuring some things out, but talked to someone personally (always nice) and now my batteries are ROCKING!
