Here’s a cool car battery charger diagram.
This very simple circuit uses a transformer ,two diodes , a capacitor and an ammeter. To charge a battery just connect the + and – terminals of the circuit to the corresponding terminals of the battery. When the battery is not charged, the ammeter reading shows 1-3 amps. When the battery is fully charged the ammeter reads Zero or nearly zero, after which the battery should be removed from the charger.

Hola de casualidad ustedes no tendran el diagrama para realizar un coche a control remoto.

Cool!Battery charger

A resistor must be added to limit the current flow or fuse to avoid short circuit. Any accident may cause overheating or fire!
cool, but is that charger a real CAR battery charger? it works on larger batteries or the small ones? please, i need to know because it looks very simple to build . I need to build it, i need it a lot. Thanks.
I believe it is but as always, proceed with caution, especially if you don't mess around with circuits much. Well, my honest advice here.

Oh, come on, Don’t ever do this. It doesn’t even have a current limiter. It is REALLY dangerous, as lead acid batts could explode (literally).
Each battery has a different max charge current (larger ones will have a really high charge current capacity), so exceeding that is REALLY DANGEROUS!!
