I seem to remember something about a "proprietary" battery, but I'm sure you could buy them separately anyways... if it is removable easily.
Fenix ARB-L1 is the name of the battery by fenix that the RC-10 brings , I see on Fenix web site that they sell an ARB-L2 rechargeable battery witch they compare with an 18650 but the RC-10 uses a smaller battery than the 18650 . In the you tube video i posted before shows the size diference of the 18650 & the ARBL1. Too remove the battery all you have to do is twist off the tail cap & Insert . i would buy 1 or 2 extra battery's if they came out for sale.
