That’s just it, the light was off. Both cells seemed to be newish, had plenty of juice, but something happened which made at least one of them quite unhappy.
Same like my GTmicro with the EBL 14500 which just… leaked. Was off, sideswitch still glowed, but when I took out the cell for whatever reason (probably to “top off”, as voltage was in the mid-3s), I saw the clear ook on the positive end that started eating at the driver.
Silkscreen (?) started peeling up as if it were cellophane, but the light still works fine after washing the living crap out of it.
