This post shows you how to make an easy 12v Battery Charger with Auto cut-off and ON Circuit for 12v lead Acid battery. This circuit is set to automatically cut-off when the battery reaches full charge. This circuit uses a transistor and a mosfet. This is a very simple circuit.
12v Battery Charger Circuit :
Matterial Required :
- Tip122 – 1no
- P55nf06 (or) IRFZ44 – 1no
- 4.7k Resistor – 1no
- 1k Resistor – 1no
- 1n4007 Diode – 1no
- 100k Pot – 1no
- LED – 1no
Tools Required :
- Soldering
- Lead
- past
- Cutter
- Component Holder
What are the wattages of the resistors?
