Cut-Off Circuit For 12V Lead Acid Battery Charging

If you are looking for a simple but effective Lead Acid battery charger cut-off circuit, then look no further. You can use this circuit in conjunction with any battery charger(except capacitive types) which do not have an automatic shut-off once the battery voltage has climbed to 14.2V(You can adjust this value with the zeners). You can modify the circuit to charge 6V lead acid batteries instead of 12V as shown in this video. Just replace the relay coil with a 6V type, use a lower voltage power supply (8-12VDC Open Circuit), replace the 12v zener leading to the base of the NPN with a 6V or 6.2V, along with the same (2) 1n4001′s in series, replace the 12V zener to the relay coil with a 6/6.2V zener, and cut the value of the LED resistor in half.Link To Schematic: For Watching!***If you enjoy watching my videos, please show your support by SUBSCRIBING, POSTING LINKS to my videos on other websites & blogs, rating a “THUMBS UP”, and watching my video playlists.
