12 Volt Battery charger
The following schematic is a high-performance battery charger for gelled electrolyte lead acid battery. Battery charger quickly recharges lead acid battery and shuts off at a full charge. Innitially, charging current has limitations to 2 Ampere. While the battery voltage goes up, current to the lead acid battery decrease, and if the current has decrease to 150 mA, the battery charger changes to a lower float voltage protecting against overcharge.
