Rated 3.8 out of 5 by 8 reviewers.
Rated 3.0 out of 5.0 by Same high price half the power I wouldn't buy the slimline battery here unless you absolutely have too, purchase the larger battery. Run-time is severely cut short on the slim battery especially if you have a power hog tool like a chainsaw or blower March 24, 2015
Rated 5.0 out of 5.0 by Works great This works just great with my 3 Ryobi products. I have the string weed whacker, the hedge trimmer and the grass blower. All three are great for yard work without messing with Gas. However; because the blower is a power hog, I purchased the second battery which this is. It allows switching batteries and continue with my work. March 3, 2015
Rated 2.0 out of 5.0 by Over-priced Got you by the short-hairs. I purchased this battery for my chain saw. The battery itself cost as much as the saw itself. This product I feel is over-priced. Convenient, but you pay for it. Recommend getting a plug-in model. January 28, 2015
Rated 3.0 out of 5.0 by Half the Power of the Larger Battery I bought this to supplement my three regular batteries only to find it has half the watt hours of those (46Wh and 93Wh). I did try to find this information out from Ryobi's site before my purchase but they didn't offer that level of detail. The power capacity is listed on the underside of the batteries. I'll get use out of this, but I'm going to have to buy another regular battery too. Shame it's not half the price! December 10, 2013
Rated 5.0 out of 5.0 by good value Bought this as a second for 40V chainsaw. Each battery lasts about 1/2 hour of on and off use. Don't know how time and use will affect the longevity. If you are doing any extensive trimming need the second battery. I am happy with the product and value April 30, 2013
Rated 5.0 out of 5.0 by Battery backup, exceellent with more than enough extended power. Met, and exceeded all expectations....Works great in conjunction with then new Lithium cahinsaw! November 11, 2014
Rated 5.0 out of 5.0 by Good battery life The battery seems to be what is advertised. I have used it 4 times and it really holds the charge well. I have not ran it out completely yet. I think the only drawback is the price. I costs more than the equipment it runs. July 9, 2013
Rated 2.0 out of 5.0 by OK Running things like a edge trimmer or hedger, battery life is about an hour or more, but if you using it for a lawnmower, less than 30 minutes. Price a little steep though. May 29, 2013
