Battery Charger Circuits

In this article the circuit starts with a 12V supply, it functions as a battery charger by employing a unique way to increase voltage over 12V and pump current into the battery. It has particular components and makes sure transistors switch effectively to prevent overheating. It provides a safe charging current of about 900mA even […]

Regular car batteries have a liquid inside, but gel cell batteries are like a special type that uses a jelly instead. This jelly makes them tougher and lets you use them in different positions. To charge these gel cell batteries safely, you need a special charger circuit. This charger is like a smart helper that […]

Thinking of a battery like a water reservoir for your device. This clever circuit acts like a watchful caretaker. It keeps an eye on the battery level and automatically gives it a little top up whenever it starts to run low. This ensures the battery is always full and ready to go perfect for things […]

What if a smart battery charger that can fill up your battery by itself and then keeps it topped off without going overboard. That is what an automatic charger with a trickle circuit does. It has a special part that watches the batteries power level voltage. While the battery is low, it pushes electricity in […]

Knowing how much electricity (current) to use is important to safely charge a battery, just like needing the right amount of water for a plant. Most people use a tool called a multimeter to measure this, but not everyone has one. Here is a cool trick you can try if you do not have a […]
