I took apart an old toothbrush (Electric) and saw that the means of recharge was simply an inductor coil. So it charges via an electromagnetic field.
The battery inside is a rechargeable AA battery. So is it possible I could overcharge the battery if I hooked up the inductor coil straight to the battery?
It doesnt output allot of power. It doesnt specify, but it was enough to light a small LED, but not spin a small motor.
Does the battery just stop recharging or what?
