Rated 3.9 out of 5 by 35 reviewers.
Rated 3.0 out of 5.0 Better than the size shipped with the chainsaw The battery shipped with the 40v Ryobi Chainsaw was worthless. It would power the saw run with no load for an average of 12 minuets and 8 under a load ( bucking a 4" tree limb). Ryobi said it if must be a bad battery and that it should last 20-30 min. The saw was returned to Home Depot and they replaced it. They had to replace the whole package, not just the battery. The new one wasn't any better so this higher capacity battery was purchased. I haven't had a chance to fully test it yet. Ryobi denies there is a problem but from my experience and that of most online reviews I've read there is. January 28, 2015
Rated 5.0 out of 5.0 by 40 volt battery review The battery is exactly what I needed and is easy to load but a little hard to take out but not a problem. I bought extra because if I order other items I can use it for them and still have another one on charge. January 20, 2015
Rated 1.0 out of 5.0 by Battery died in 4 months with light usage Not impressed!! Battery came with a string trimmer. Used naybe 20 or 30 times. Showed fully cgarged in the charger but the tool would not do anything and the bat would show one bar after about 15 seconeds is the ? button was pressed. January 7, 2015
Rated 5.0 out of 5.0 by Ryobi 40-Volt Makes TIm Taylor Proud I now own both a leaf blower and the string trimmer with accessories that use the 40-V Ryobi battery system. The power and longevity of the leaf blower battery are amazing. I also have several 18-V Ryobi Lithium Ion tools. It's been good to be standardized on this system. When my kids come over to borrow something, I have most of them on the same battery systems; so they have chargers for the tools they borrow. December 26, 2014
Rated 4.0 out of 5.0 by Great battery I bought two of these for my Ryobi16 in. 40-Volt Lithium-ion Cordless Walk-Behind Lawn Mower. The charge on one battery lasted almost the total time it takes to mow my entire yard (it's not a huge yard though). I would recommend these batteries. August 12, 2014
