    • Good battery for intended work on mini chainsaw.
Number of Items: 1
This battery works great on the mini chainsaw. Runs about 60 minutes per charge.

    • Apparently original batteries don't last.
Number of Items: 1
I purchased this battery for the mini chainsaw. I was using it and it would stop cutting a limb about half way through. I thought the mini chainsaw was getting ready to die. But a master electrician said it was the battery. The batteries that came with the unit die when starting to cut. I even went online to see if there were issues with the chainsaw. Nothing. So I bought this battery. And the old batteries were only a year and a half old. Put new battery in and it works/cuts like new. Hoping it last. ... show more

    • If you need 5 seconds of work done this bats for you.
Number of Items: 1
It works, barely. Lasts long enough to trigger but that’s it. Original battery on small saw was 2.0 ah and it worked great for several minutes, enough to get work done, but this replacement doesn’t even get the motor warmed up.
