I have a Ni-Cd battery (8AA) 700 mAh 9.6 V, taken from an RC car. However, is no longer capable of powering up sufficiently the RC car.
Specifically, servo works fine but motor can't spin. Instead, there is a sound came from the PCB (I guess from the conductive area of motor's power cables). In addition, after a while, servo can't turn the wheels.
Battery is fully charged (multimeter is showing 10.2 V). However, I can't imagine that there is something else wrong. Is there any way to ensure that battery isn't working properly? Could this mulfunction be due to the amperage?
Battery neither has been charged for a long time, nor was in operation. Anyway, how should I treat to a Ni-Cd battery?
Thank's in advance.
