![]() ![]() Note that this is only a problem when driving a motor that is too small for the load. Something that I discovered when I was a kid. When you have much larger capacity cells driving the motor that is too small to properly drive the load, the motor gets hotter and hotter until something fails. Both primary and secondary batteries are available in C size. With small cells (a small battery), the cells deplete fairly quickly and the motor temperature spikes to some high value, then decays as the cells decay. C batteries are the standard size for dry cells and offer 1.5V nominal voltage. We only stock the highest quality C batteries. The damage that occurs is strictly thermal and happens when the motor tries to drive the load but gets too hot while doing so. C batteries are used in medium and high drain applications such as toys, photo strobes, games and torches. There appears to be some confusion regarding my statement about how using a larger-capacity battery can lead to motor damage if the motor is too small to properly drive the load. That said - if the motor is under-sized for the load, the extra current available from the battery can lead to motor damage. The motor will consume only as much current that it requires at that point in time. ![]()
