Contact UsWhat power adapter do I need to charge a 7.2V 4000mAh battery?
9V and 500mA are both slightly too high. The main concern is the 9V, since you should be using 8.5V. The 500mA isn''t too much higher, but you would need to reduce the charge time. Now if you use that to charge your battery, it will charge. But the over voltage will be damaging it. You could probably solve this problem with a low loss diode.
