Convert DeWalt Cordless Screwdriver Battery to 18650 cell

15 years ago I received an amazing present from a friend – DeWalt Cordless Screwdriver – DC600 Type 1. It was a great tool and I’m really happy that he chose exactly this model for my daily PC work with desktop computers and other electrical devices.

I used it more than thousand times and it was always serving as a stable and compact tool. But as any other device which is using batteries for power supply, soon or later you reach the tragic moment when you need to replace them.

New batteries at online shops are really expensive, so I decided to make an experiment and try to save the standard original battery by using one of the most common cells you can find in laptops – the famous 18650 cell. You can find tutorial on how to retrieve these type of cells from laptop batteries HERE
