    • Good battery
Style: 4.0 AH Battery + Charger
I use this in my 1/2 mid-torque impact. I doesn’t run out of power very quickly. Holds good power for the tool… one time I left my lights on in my truck so the battery died, and I used some scrap metal and jumper cables, hooked it up to my 20v craftsman battery and started my truck.

    • Craftsman v20

Works great. Now I don't have to wait a little over an hour to charge a 2 ah battery. Charges a 2ah battery ind 30 minutes and a 4 ah in an hour. Nice upgrade.

    • Updated my battery and charger perfectly
Style: 4.0 AH Battery + Charger
My Craftsman battery stopped charging, but I wasn’t sure if the charger or the battery were to blame. This let me test both, and I figured I’d have a backup of one or the other. Turns out in my case it was the charger that somehow went bad, so I now have an extra battery, which is perfect.
