The battery is not rechargeable. Yeah I do wonder if it actually does. My Lincoln Helmet, as per the above Photo has the Shade/Grind control with the switch Position. The Manual makes no mention of that knob turning it off. Pretty Contradictory actually, as the Specs Table in the Manual States:- Power Supply - Solar Cells - No batteries required. Power On/Off - Fully Automatic. My two problem ones DO have Batteries. My oldest Lincoln Ultra Shade is still fine & assume it truly is Solar Powered. Interestingly also, the New Unimig I bought a few days ago has 2 CR 2450's & still no power switch. All controls on an LCD Display, with the knob just being an encoder. Does have a Battery Indicator on the Screen & a Low Battery Led though.
