Picture of DIY 9 Volt Battery Connector for Free

Usually cheap 9 volt battery connectors that you can buy are flimsy and don't last for long. Here is a way to make yourself a battery terminal that will last. Oh, did I mention it's almost free?

You will need:

* dead 9 volt battery
* pliers
* sharp knife
* soldering iron + solder + flux
* red and black wire
* a piece of heatshrink tube
* a thin ziptie

Step 1: Rip Apart a 9 Volt Battery

Step 2:

Strip and tin a couple of wires. Preferably - black and red. Note the polarity - the red wire goes to the "crown like" terminal.

Step 4:

Solder the wires to the terminals. Watch the polarity! Don't overheat while soldering, plastic tends to melt rather quickly.

Step 5:

Now you have a proper 9 volt battery connector.
