Simple Nimh Battery Charger Circuit Diagram

By | September 5, 2017



If you're an electronics enthusiast, you've probably heard of the relatively simple 7800- series NiMH battery charger circuit. This type of circuit is an ideal way to quickly and safely charge your NiMH battery without the need for a special charger.

The 7800-series NiMH battery charger circuit is designed for users who want to quickly and efficiently charge their low voltage NiMH batteries and not have to worry about buying a special charger. With this circuit, you can avoid having to buy a dedicated charger and simply use the basic components found in any home.

The whole circuit is very straightforward and easy to build. The only components used are a few resistors, two LEDs (for charging status), and a capacitor. The circuit relies on a simple current limiting circuit that allows the user to safely charge the NiMH battery and prevent it from overcharging.

The charging process is relatively simple; when the NiMH battery is connected to the circuit, the resistor limits the current to a safe level. When the NiMH battery reaches its maximum capacity, the LED lights up indicating the battery is properly charged. Once the battery is fully charged, the LED will shut off and the process is complete.

In addition to being simple and efficient, the 7800-series NiMH battery charger circuit is also quite affordable. All of the components can easily be found at most electronics stores and the entire circuit can be assembled using relatively inexpensive parts.

For those interested in building their own NiMH battery charger, a 7800-series NiMH battery charger circuit diagram is readily available online. Whether you're a hobbyist or an experienced electronics enthusiast, with the help of a simple diagram, you can easily build your own NiMH battery charger circuit with relative ease.
