Simple Car Battery Charger

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 fully charged the ammeter reads Zero or nearly zero, after which the battery should be removed from the charger.
