Universal Battery Charger Circuit with TIP35 Transistor
The universal battery charger circuit with a TIP35 transistor is shown below. This circuit explains how to charge all kinds of batteries irrespective of the current capacity (or) the AH level. So this battery charger circuit is used to charge any kind of battery without worrying about safety and compatibility issues.

Universal Battery Charger Circuit with TIP35 Transistor
Working
This 12V universal simple automatic battery charger circuit includes an op-amp accountable for governing the state of the battery & triggering the LED indicator when the charging process is finished. So this circuit has a three-stage resistive divider that allows the reference voltage mainly for the op-amps. Once the current supply falls under the half ampere the connected battery will cut off.
So this circuit begins to oscillate by working the transistor that switches current to the light emitting diode which indicates the glowing & indicating the complete charge range of the battery. Here bridge rectifier’s input power supply may need to be >10 Amp. So filter capacitor in this circuit can be connected onto the plate (or) twisted within the cabinet with a pair of plastic seals and connected in parallel with the +ve and -ve terminals of the rectifier bridge.
Do not attach the battery but first provide 14.4Volts from the DC input & adjust the 10K preset, thus the green LED lights & the red LED will turn OFF. After that, the 12V 200AH battery must be connected, then the input will be switched on & the battery starts charging. So the red color LED will glow when the battery starts charging. Once it attains 14.4V, then the red LED turns OFF & the green color LED will light up which indicates the completely charged condition of the battery.
Thus, this automatic universal battery charger circuit is an essential tool that can charge any type of battery securely and efficiently to provide a power supply to their devices. The convenience & versatility it provides are unmatched, and it has the potential to extensively decrease electronic waste by prolonging the lifetime of our batteries.
