What to do with the old cordless tools after the batteries won’t hold the charge anymore.
Usually, the cost of replacement batteries justify buying a new (and more powerful) cordless drill set.
I saw on the “Instructables” website someone cut the battery adapter off of an old cordless drill and attached jumper wires to power the drill from a truck battery.
It reminded me of a set my stepfather gave me when he upgraded his cordless tools. It is a duffel bag full of junk batteries, 2 drills, a sawsall, saber saw, flashlight, etc. A few of the batteries in this set had screws so the battery could be taken apart. I modified the original idea and gutted one of the batteries to attach the jumper wires so that all of the tools can be used without hacking them all up. I used a 12' long cord to give some freedom of movement.
The tools have plenty of power when used with my 12v marine battery even though they are "18v"
Obviously, they aren’t cordless when using this way (I wouldn’t want to drag a car battery around with me while hanging drywall) but there’s always something in my home shop with a battery in it and power tools could be useful out in the sticks somewhere- i.e. like deer camp.
