Solved Can I Charge My Own Battery From A Power Supply Irobot Roomba 4100

Chosen Solution

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?

Feel it to see how warm it is, if warm OK, if hot it’s not
