A Solution to Your Empty Batteries

Empty battery, we all experience it. It’s really annoying to see an empty battery. Much of the devices applications nowadays eat up too much of our battery juice. Although devices have chargers, what I really don’t like about it is that some chargers cannot be used on cars. When you’re on a long journey and use your gadgets to entertain yourself, battery life is a nightmare.

So I wanted to create a universal battery charger that’ low cost, yes you heard it folks, at a very affordable cost. This universal charger is for NiCD – NiMH batteries. This circuit is ideal for car use (just what I needed for). The cool thing about this is it has the ability to transform mains adapter into a charger.  The circuit has an LED to indicate charging. This project can be built on a general PCB or a veroboard.
