I found out that the charge light wasn't coming on because I was using a
different AC adapter that had a lower voltage than the battery.

| (...) Well that would do it---it would discharge your battery. You actually should be getting more like 9.6 to 10v from a fully charged battery. Why don't you get an adatper that works and charge your battery until it's slightly warm and then see if (...) (29 years ago, 18-Mar-96, to lugnet.robotics.handyboard)
