I have an old DEWALT cordless drill. The battery no longer holds its charge. I contacted DEWALT ages back about a replacement battery but they quoted $85 PLUS P&P… I am sad to say that my trusty old drill has sat unused since. I purchased a new cheaper drill for half the price.
But all is not lost as thanks to the videos below, I am now able to breathe life back in to my trusty old DWALT drill! I can ‘hot rod’ and repair the battery for less than $20! I am over the moon! If you have an old battery drill, or any other battery power tool that’s no longer charging or holding its charge, DON’T pay top dollar for a replacement battery, or a new tool. Hot-rod the battery pack and replace the battery cells. It’s pretty straightforward to do. Watch the video below.
UPDATE: I have since stumbled across another video tutorial. This one shows how to upgrade your old NiCad battery drills etc, to lithium battery drills! This means you don’t need to purchase a new drill, to take advantage of the newer, much improved lithium battery technology. You can simply upgrade your old drill’s battery by replacing the battery cells in it.
