Tired old Dewalt dw056 impact driver

It needs a new battery pack. Rechargeable batteries eventually wear out and no longer hold a charge. The tool runs only briefly and the battery is exhausted again. The big home centers and online sources sell replacements. There are also companies that say they can rebuild your battery pack at much lower cost than replacement. I have no experience with them.

It's not a simple project, and should only be done by someone who is an electrical technician. But, you can save money by repairing your old battery pack yourself.

If you look at the battery pack it might be screwed together (my 18 volt impact driver is). Inside you will find a series of batteries linked together by tabs. You can go to Ebay and find a supplier of these batteries. After your batteries come, you can replace the batteries in the same configuration as they were before. Dispose of your old batteries in a manner suitable for hazardous materials.
This process will cost you less than buying a new battery pack.

You can also do this with computer batteries. I found one of my computers only had two dead batteries out of eight. The cost to replace them was about $15, a lot less than a replacement battery for around $100. Just make sure you use the same batteries to replace the others, and use all other precautions. Again, don't do this if you are not an electrical technician.
