Thanks for the technical post. I hope I'm not diverting the thread by asking a few follow up question (OP, please let me know if I should start a separate thread).
So the chargers that come with camera batteries are OK? Usually cheap chargers are not that healthy for accumulators. I guess despite being cheap, the chargers that come with cameras have their charging current matched to the accumulators and hence won't cause damage (despite the fact that probably neither they nor the accumulators have temperature sensors).
Does the "fully charged storage causes higher capacity loss" phenomenon also apply to hybrids, such as Sanyo Eneloops?
Any idea how to solve the conundrum of wanting to avoid capacity loss (i.e., store at 40% charge) but preferring a fully charged accumulator when it is needed? Ideally, one would just fully charge right before a particular application, right?
