Rated 4 out of 5 by 31 reviewers.
Rated 4 out of 5 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
Rated 5 out of 5 by Great Battery, Worth the Price Though it may seem pricey, this battery is worth every penny to me. I originally had to recharge in the middle of trimming and edging my yard. I ordered a second battery and now I can quickly switch batteries and don't have to wait for my battery to recharge before finishing the job. These batteries last about 30-45 minutes depending on how heavy the load is I'm putting on my trimmer/edger. The quick charging time is also nice for when I do larger yards for friends or family because if one battery runs out I can throw it on the charger and have it half charged by the time my second battery runs out.

Rated 1 out of 5 by Battery problems In less than 3 months of use (several tools) I have had 4 batteries go bad. I am waiting for 2 replacement batteries as I write this. (The store was good enough to replace the first 2 defective batteries on the spot.) Both replacement batteries have failed in an identical manner. Battery gauge reads fully charged, but fail to operate in any of my 40 volt tools. Both of my chargers appear to work correctly (no defect indicated on either battery). The tools are great, but useless unless the battery issue gets resolved. October 30, 2014
Rated 4 out of 5 by good but potential problem?? Good products (blower, weed eater), with strong batteries. BUT I note complaints of battery failure after some use. Unfortunately rechargeable batteries do fail in time. Price is high to replace. Takes more than 2 hours to recharge fully. Expect to need 2 to 3 batteries for a blower, less for an edger.

Rated 5 out of 5 by 40 Volt Battery This is a very good battery - It has lights on the back to tell you how much power is remaining or charge required - Just push a button - But be careful when you purchase one - So you get what you need - There are two (2) models - One has more power than the other - The more powerful one has more of an open top and is more expensive (That is what I purchased). The battery is really handy but cost nearly as much as the weed-eater it is used in. It slides into the charger / weed-eater O.K. but sometimes need some extra nudging - With modern technology I believe they could have made it slide easier. September 30, 2014
