I am just doing some father/son widdling with the boy today. He found some electric plastic gun thing on the road so he brought it home and we were messing with it. I got everything working on it but now charging the battery.
It is a 6x500mah 7.2V pack. So, 6, AA, 1.5V, 500mAh cells. I am currently using 1 of the 50 power supplies I had laying around. I am charging at 350mA and voltage is at 9.2V. I cannot remember what the safe voltage is for NiCad or NiMH cells. I want to say about 120% of cell voltage but cannot remember.
I am also figuring the charge time will be approx 1.5hrs. This is nothing we plan to keep and not to worried about it. Just screwing around today so no worried on exact science today...
