Rated 5 out of 5 by from Small and Powerful Great battery!!! Easy to store when not in use, and powerful enough to complete a job without recharging, Am really pleased with Ryobi quality.

Rated 5 out of 5 by from Excellent battery life I bought this to avoid using gas, and was worried if it was going to have enough power to do my while yard, as I am on 1/3 of an acre, but the battery lasted the whole yard and still had power left over!

Rated 5 out of 5 by from Nothing better than Original I bought my lawn mower in 2016, so the battery had run its course, I bought a generic battery and the lawn mower had hardly any power or it would not last as long as before, so I thought my lawn mower was also bad (because it was old) and I use it very often, I was about to buy a new one when I decided to just buy an original battery and Yes best decision ever... Lawn mower is working like the day I bought it I can doo my whole yard with one charge and still 2 lights remain on the battery, Nothing beats Original I recommend this battery 100%
