Well, then, they are trying to protect the batteries it sounds like. The toyota Prius uses nimh batteries and they only charge them to 80% to extend their life, so I suspect that is what is going on with the 15-minute batteries as well. I'd rather get a lot of cycles out of a rechargable than get long cycles, I hate to use them down to the end because recording memos goes nuts if you do so.
