Mods, move this elsewhere if need be. Anyway--
Do Li-Ion 18650 batteries ever peak higher than the norm of 3.7V. I ask because I have two 18650s that my multimeter shows are well above 4V. One reads 4.15V and the other at 4.25V.
I tested numerous other batteries whose voltage were within spec; i.e., some AAA reading 1.48V and 1.32V; a AA at 1.48V; some [dying] Li-Ion 123 at 3.3V and last, a different [dying] 18650 at 3.15V.
I'm confident I've got my multimeter hooked up right; black is plugged into COM and red is plugged into V[omega]mA, right?
