Rated 4 out of 5 by from middle of the road 40v battery not the biggest out there, but larger than the 2ah 40v that we already had. purchased to use with a ryobi snowblower. used half of the battery in a bout 10 minutes of clearing about 1" of powder.

Rated 5 out of 5 by from Great replacement battery My original Ryobi battery for the mower was many years old and not up to heavy, longer loads. HD had this on sale ($30 off) the week of Black Friday, so I took the plunge and glad I did. It us just a bit too tall to fit my (gen 1) mower, so the battery cover does not close all the way-not a big deal. I have used it with our blower and it has extended range time with no hot spots felt after being completely drained.

Rated 5 out of 5 by from Good battery Good capacity, very sturdy. I've dropped them a few times onto solid concrete, minor cosmetic damage but battery has no issues.
