DIY Coin Cell Holder

Step 2 We Can Work It Out

Slicing out a bit of the N type battery holder will create a lovely holder for my small stack of coin cell batteries. Decide how many cells you need for your project and put them in the holder against the spring. Put a little pressure on them and note the length from the cells to the other end of the holder. This will give you an idea of how much you need to cut out of the middle. This design is a bit forgiving, though with the spring, and mine can hold 3 or 4 cells with no problem either way.

You can use a small fine toothed saw to cut out the bit of battery holder. If your saw is in a storage unit somewhere like mine is, a set of sharp wire cutters will work as well. Just cut down the sides, fold the base back and cut through that as well. I used a Dremel tool with a sanding band on it to clean up the edges and make them straight. Leave a bit extra with each cut to allow for this sanding.
