Yeah, I’m frequently recharging around 3.2v - 3.5v now that I have so many spares it’s just too easy to pop in a fresh cell and the attended recharges don’t take as long. I’ve done a few around 3.1v but that’s fairly rare - mostly with the LGs.
The only light I’ve run dead off alkalines is a SK68 clone on NiMHs. It dims somewhat and then dies. Lot shorter run time than I expected, but it’s pushing a bunch of current. I haven’t run my 3 mode version dead yet, so no idea of how long I’ll get with it on low.
Couple more salvaging first for me in this thread.
