It happens that there is very little left to do, but the battery died . Waiting for charging could take half an hour or even longer . This is why I made an additional power supply for my cordless tools
AC/DC power supply 90V~260V AC Input, Single Output 500w 18v
Plastic Case For DeWALT 18V Battery DC9096
If I to change anything about this set up it is the size of the tool box.
The one I got is 6.5" x 7" x 15" and it is a little crowded with the 18' long power cord coiled up inside of it
and possibly splice the power cord with a power connector right at the battery, so if I need to power up a 12V tool I could simply swap a battery with a step down housed inside of the battery/adapter case. The hardest part of the whole project is the search for the 18V power supply which can produce 20A +
