A battery holder is designed to securely hold batteries. It also serves as an additional battery container. Sometimes, it can be used to replace an old, damaged battery case. If you're into DIY radios or just a radio enthusiast, it's hard to live without such a box.
Battery holder and its types
Each power supply requires its own mounting hardware. Based on this, several mounting options are available:
They can have one, two, or more compartments. The main options are listed below.
How to use?
First, insert the batteries into the container and then connect them to the desired device using wires. Using the device is straightforward.
Round ones are a bit tricky. If you're mounting them on a board, you'll need to desolder the old container, remove the excess tin, and then insert the new ones. Then, using a soldering iron, solder, rosin, or soldering acid, solder the holder back onto the board. Then, insert the battery.
You can also make this device yourself. But it will require some ingenuity. You'll need plastic, a spring, and metal plates.
