Circuit Diagram
Circuit Explanation
This simple universal automatic 12V battery charger circuit can charge all types of batteries regardless of their current capacity or AH level.
The circuit consists of an operational amplifier responsible for governing the battery’s state and triggering the LED indicator once the charging process is completed. The circuit includes a three-stage resistive divider that enables the reference voltage for the operational amplifier. When the current drops below the half-ampere, the battery cut-off takes place. The circuit starts to oscillate by operating the transistor that switches current to the LED resulting in it glowing and indicating the full charge level of the battery.
The input power supply’s bridge rectifier may need to be above 10 amperes. The filter capacitor could be bolted onto the plate or twisted in the cabinet by using a couple of plastic seals and joined in parallel with the positive and negative terminals of the rectifier bridge.
Instructions on how to set up the automatic universal battery charger circuit.
Do not connect the battery yet first apply 14.4V from the DC input side and adjust the 10K preset such that the green LED just lights and the red LED shuts off. Once this is done, the 12V 200AH battery can be connected, the input switched on, and the battery can begin charging. The red LED will glow while the battery is charging, and as soon as it reaches 14.4V, the red LED shuts off, and the green LED lights up, indicating the full charged status of the battery.
Final Words
In conclusion, the Automatic Universal Battery Charger Circuit is a game-changer in the world of battery technology. Its ability to charge any battery safely and efficiently makes it an essential tool for anyone who relies on batteries to power their devices. The convenience and versatility it offers are unmatched, and it has the potential to significantly reduce electronic waste by prolonging the lifespan of our batteries.
