1 Can I charge my own battery from a power supply?
So my Roomba 4100 won’t charge the battery. So I pulled it out and hooked it up to my bench variable DC power supply. The battery is 14.4VDC, so I set the power supply at 14.5VDC.
So far it is drawing about 0.24 amp. (for the past hour)
Am I doing a bad thing? Is it going to explode or catch fire?
