My battery/OS were interacting the exact same way on my 8 day old .893 last night and I cranked everything all the way on to get the battery drained a start a cal cycle. I have always wondered if LiIons had to be conditioned (or calibrated) like NiCads. Somebody recently told me that it was witchcraft to apply NiCad thinking to LiIons and it really had no effect. Thoughts? Genuine knowledge? Or is it just that we're syncing the battery's peak and zero to the meter in the device and not physically changing the battery.
