can tweak this circuit for a 24V charger. The charger circuit gives full wave rectified output voltage for charging lead acid batteries. The current reading become almost zero hen the battery is fully charged. the center tapped transformer, the diodes D1 and D2 constitute the unregulated supply portion. The One Ohm wire wound resistor of 10W connected in series controls the charging current and prevents the battery from overcharging. The LED shows the presence of the output voltage. Also its brightness depends on the charging rate.
