12V Battery Charger Homemade


A 12V Battery Charger Homemade is a device that allows you to recharge your batteries when they’ve run out of power. These chargers come in a variety of forms, including wall chargers, portable chargers, and even solar-powered chargers. Wall chargers are the most common type of charger and are often included with new electronics such as phones and laptops.

Portable chargers are great for on-the-go charging, allowing you to keep your devices powered up while you’re away from home. Solar-powered chargers use energy from the sun to recharge your batteries, making them an eco-friendly option. When using a battery charger, it’s important to follow manufacturer guidelines and ensure you’re using the correct charger for your device to avoid damaging your battery or device.

In this video I have made a Battery Charger Homemade with a feature to indicate when battery is fully charged. I have tried to make this video as easy as it could be and used common components. I Hope it would be helpful.

Explanation of 12V Battery Charger Homemade

Making a 12V battery charger is a simple and cost-effective project that anyone can tackle. First, you’ll need to gather some basic materials, including a transformer, diodes, capacitors, and resistors. Once you have your components, begin by wiring the transformer’s primary winding to the AC power source and connecting the secondary winding to the bridge rectifier made of four diodes wired in a diamond pattern.

Add a filter capacitor parallel to the bridge output for smooth DC and regulate it with an adjustable voltage regulator IC. Finally, add some clamps or alligator clips to connect it to your 12V battery. Remember always use proper electrical safety precautions when working with electricity. Overall, this DIY project won’t just save you money but also give you satisfaction knowing that you’ve built something yourself that is practical in everyday life.
