The laptop is an HP Pavilion if that matters. I found out yesterday that the batt. should not remain in play when running on ac power. It's a six cell batt 10.8 volt 47whr. How long do these hold a charge when unused? How long to top off after sitting around in limbo for a month? Anyone know the self discharge rate? None of this info is in the help section, if you could call it that. Thanks for your time.
