I have a Ni Cad battery Charger as part of a Black and Decker Ve3rsa pack system. They recommend a 14 Hour charge the first time you charge them. I have basically ruined one set of batteries forgetting to pull them out of the charger in a timely manner. I measured the power supply to the base it is approx. 9V AC unloaded. So I'm going to try and built this circuit before I order a new set of batterys.
