Power Tool Repair Made Easy

Step 7 Zap NiCad Batteries Back to Life

Battery powered tools usually get thrown away when the battery no longer holds a charge.
If it's a NiCad battery pack, you can usually make it work again by zapping it as shown here.
There's usually nothing else wrong with the tool. Thank you "Garbage Santa"!

If your battery pack doesn't come back to life you can take it apart and zap or replace individual cells.

If your battery pack is made of something other than NiCads, don't despair.
You can take them apart , replace individual cells, or empty your dead pack and wire that connector to a different battery pack that is good. Laptop computers are a good source of battery packs also! All you have to do is make sure you assemble a pack with a voltage close to what your tool needs, and the charger is intended for the battery chemistry you end up using.
Be careful with the wiring. A reverse voltage will burn out the speed controller of your tool.

WARNING: Read about the dangers of the type of battery you are using. Ignorance is no defense against anything.

Watch the video and see how zapping is done.
