Re: What was that quote allegedly from Cardinal Richelieu again?

There seems to be some question regarding exactly what levels to keep lithium-ion batteries at. My understanding, and my long habit, is discharge to around 40%, then charge to around 95%, which is why I have my androids programmed to speak up at those levels. 40 to 50% charge when storing, and store them cool (I've seen recommendations of "in the 'fridge"). Motorola Moto Z series battery mods (batteries that clip on the back and charge the phones internal battery) are programmed to keep the internal battery charged at 80%. I guess they know more about their batteries than I do. I doubt if keeping them "active" helps prolong life, they do have a limited number of charge / discharge cycles.

Apparently lithium-titanium batteries have none of those limits, though I've not found a lot of info about them. On the other hand, it's always the way, new battery technologies claim to have none of the limitations of the old tech they are replacing, until everyone's been using them for a decade, then we find their limits the hard way. Lithium-ion has half the energy density of lithium-ion, but if you are keeping your lithium-ions between 40 and 95%, then you're only using about half the energy density anyway.
