This video will show you how to fix a bad or old NiCd battery for your cordless power tools. You need to have a power source that is double the voltage of your current battery. So if your battery is 18V, then you need a power source at 36V. You can use other cordless batteries and connect it in series.
The procedure is this:
1) let your bad battery drain to no voltage
2) connect the (-) lead of the 36V to the (-) lead of the 18V battery
3) quickly tap the (+) lead of the 36V to the (+) lead of the 18V battery, and repeat this quick tapping for 6-7 seconds, then STOP tapping it
4) you can use a multimeter to check the old battery and you should see a voltage of what that battery is rated for
5) now let the old battery sit for 15 minutes so the cells inside can cool down
6) put the old battery in the proper charger and let it charge fully
7) the battery should be as good as new
8) if it's not, you can repeat the above procedure couple more times
