Introduction
Batteries would have no application if we don’t have their chargers with them. Charger circuits influence electronic gadgets and circuits. The charger circuits rely upon the battery type. Typical electronic gadgets use various batteries for their circuits. For instance, consider the Lead Acid Battery Charger Circuit, the charger circuit it used probably doesn’t get used by some others. In this tutorial, we are going to “Lead Acid Battery Charger Circuit”
An Overview of Lead Acid Battery
Lead Acid Battery battery has two electrodes drowned in sulphuric acid electrolyte. Grains of metallic lead oxide material make the positive electrode, and its negative electrode is connected to a grid of metallic lead. This battery is rechargeable and below we have given its charging circuit details. We usually use the battery in emergency lighting circuits, battery-operated vehicles, etc.

Lead Acid Battery Charger Circuit
Working Explanation
This leads Acid Battery Charger Circuit, which at first uses the transformer that steps down AC voltage from 230V to 15V. After that, it needs a bridge rectifier circuit to convert that Ac voltage to the DC voltage. After the rectifier circuit, it may have ripples in it, the capacitor in the circuit would remove that. This IC takes the DC input and regulates that. There is a switch present in the circuit that decides the output voltage Since this circuit can charge through 6V or 12V. When the switch is closed, the charger provides the 6V. On the output side, there is an LED, that shows the presence of DC voltage.
Application and Uses
The circuit is for the Lead Acid Battery Charger and can be utilized everywhere where this battery may get used. For example,
- Emergency lighting circuits
- In case of power failure, power sump pumps.
- Electrical vehicles, etc
