Batt Build

Here is a cheap, easy, and quick way to build yourself a 175mah NiMH battery. 

1) Go to your local hardware store and pick up a rechargeable 9V battery. I found this energizer for about $10. If you purchase two you can build three 4 cell batteries. 

2) Cut the top off the battery.

3) Pull out the inside fo the battery. You will find 7 cell.

4) Cut the tabs off the battery

5) Remove the cell for the plastic. They should slide out.

6) Heat shrink each cell. If you don't they will short out.

7) Solder the cells together. Add a battery lead and heat shrink the pack. You now have a nice little 175mha NiMh rechargeable battery.
