I just realized one thing I could do: I can take the "good" cells (top battery) and swap them into the bottom battery - it's the original battery from my newer laptop, just replaced this summer. I should have done that in the first place, instead of buying a new $60 battery. Wasn't thinking!

That would give me a 2nd battery. I wonder if I could parallel them somehow that wouldn't freak out the computer/battery circuit...

Guitar: my limited understanding is you can charge them "safely" at low current until they approach full voltage. That's when the potential for trouble starts. So, if you don't have a smart charger, and are willing to give up some capacity (by stopping the charge a little early), you can use a dumb charging method.

Robert: 14.8v.... yes! Reminded me of another potential idea I had: a "boost" pack to support alternator-less driving. Something relatively light & portable that could be plugged into the cigarette lighter.

If I could track down some more decent cells, that might be a project.

I keep thinking of this (and probably saying it) but I may have a couple of sources for used cells. I know a guy who runs a computer store, and another who runs a Black & Decker warranty repair depot. I wonder if he's handling cordless lithium stuff in his work ...
