  • True Craftsman
Style: V20 Battery Only
I was lucky enough to find these on sale. 2 4.0 AmH Craftsman 20V batteries for about $30. I’ve been using them for months now and still hold a charge well. Built an entire chicken stand with two roosts on one battery, swapping it between the Circular Saw and Impact Drill (both Craftsman). I’ve dropped it a few times as well and is a tried and tested Craftsman product. Would buy from seller again. ... show more

  • Works GREAT
Style: V20 Battery Only
Small but mighty hand chainsaw. Easily cuts through smaller branches and actually works on a branch up to 4" in diameter.

  • This appears fully comparable to my other V20 4 amp battery
Style: V20 Battery Only
I bought this for $39, which was the lowest price I had ever seen for this size. I closely compared it to a 4 y/o battery. Slight internal differences, slightly shorter screws, but exact same weight. I did NOT unpack and compare actual cells. I believe that this is a genuine Craftsman battery for a great price (time will tell). ... show more

  • Battery last

Holds charge and last longer than my 20v one.

  • No Charger!
Style: V20 Battery Only
Battery looks fine like my other Craftsman batteries. However, this one comes without a charger. Since I have others this is not a problem but if you don't already have extra chargers, this could be an issue.

  • Great
Style: V20 Battery Only
I purchased a Craftsman blower and trimmer set and LOVE them, however I needed an endless power supply so I purchased two more batteries. They all stay charged for a long time, easy to change, great functionality, perfect fit, and I can work on big projects all day.
