It has (2) 18650 6800 mah 4.2v batteries in it now. The charge doesn't last long anymore. Searching, I only find numbers lower than 6800, and voltages lower than 4.2. Mostly 3.7. I know nothing about batteries like these, other than the 4.2 is voltage. I think the 18650 is a type, like a AA or AAA, etc. I'd hate to have to throw out the light because I can't get batteries.
Anyone familiar?
