Oops, sorry! I really didn't mean it that way. Mea culpa, I usually read my posts over and look for such things before hitting "send." :-( > and then you top it off with no knowledge of batteries! Yep, guilty as charged. I admit that I have very little experience with lithium thus far. That said, I've read some, and I've never seen any secondary lithium chemistry with a nominal cell voltage of 4.2 volts. The highest nominal voltage I see here https://en.wikipedia.org/wiki/Lithium-ion_battery is 3.7 volts per cell for NMC type. I looked up lithium manganese dioxide, and all I found were references to primary batteries. I must be missing something here. Maybe it's because my freshman chemistry and physics were over 40 years ago. PS - I just saw Roland's later post. Apparently 4.2v is the >maximum charging< voltage, not the nominal voltage. So that makes more sense. > > It's obvious they are leaf batteries. Sorry, that wasn't obvious to me. Knowing that probably wouldn't have made it any clearer to me anyway, though. :-( David Roden - Akron, Ohio, USA EVDL Administrator = = = = = = = = = = = = = = = = = = = = = = = = = = = = = EVDL Information: http://www.evdl.org/help/ = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Note: mail sent to "evpost" and "etpost" addresses will not reach me.
