In this tutorial, we are going to demonstrate how to make an automatic 6V 4.5h battery charger that can charge 6V battery types with a limit running from 4.5Ah. The proposed 6V 4.5h battery charger is highlighting rich and stuffed with a few security and accommodation capacities, yet basic design. We will likewise figure out how to charge a standard 6V 4.5h battery and its significant charging parameters. The circuit is programmed so that when the battery will turn out to be full charge it will stop charging.

Battery Charger Circuit
Working Explanation
Here is a 6V 4.5 AH battery charger circuit that can charge 6V 4.5 AH SLA Batteries. The schematic is basic and utilizes just not many parts. IC LM317T is the core of the circuit. Use transformer 230 AC to 9V/500mA.
The circuit is a 6V LM317T voltage and current control battery charger circuit which produces a regulated 6V DC yield.
The transformer T1 steps down the info 230V/50HZ AC supply to a 6V AC. At that point, it changed over to a 6V DC, by a bridge rectifier circuit. The capacitor C1 channels the rectifier yield.
The circuit utilizes an LM317T regulator, which is an adjustable linear positive voltage regulator which can work in an input voltage of 3-40V.
Applications and Uses
These kinds of circuits are extremely valuable for solar-powered garden light and can likewise be utilized in different circuits like emergency LED lamps and so on.
