Rated 5 out of 5 by from Awesome Battery! I had received a backpack blower last year as a gift. The battery that came with it was great, but this one is awesome. Sure, it's a little heavy, but that's to be expected for something with as much juice as this has. I have been able to blow-out my garage, crawl space, driveway, and all around my property without going down even one bar. I also have a battery-operated lawnmower that this fits in, and was able to mow my half-acre lot without stopping. Definitely recommend!

Rated 5 out of 5 by from Holy Runtime I got this battery a few weeks ago and it has made my runtime on my RY401130 double! This is an awesome battery and I would recommend it to everyone.

Rated 4 out of 5 by from Good value for the money Purchased it with the Jet Blower about 1 month ago. Used weekly so far. I just purchased the hedge trimmer and it does the job. It has plenty of juice to power the blower and trimmer, but I wish it would last longer. I get about 45 minutes before it needs to be recharged. (Keep in mind I'm used to gas-powered everything) It charges quickly.

Rated 5 out of 5 by from Great run time A little heavier than the smaller battery but worth it's weight in gold for much longer run time. two and one half acres of trimming and weed wacking used to take two batteries. Completed the job with this one battery and still had two bars left on the battery fuel gauge. JUst plan for longer charge time.

Rated 5 out of 5 by from Power to finish the job! I have an acre and half yard and this powerful battery can finish the job! Never buy gas again. My new mower and this battery are a great combination.

Rated 5 out of 5 by from Excellent run time! I got this around a month ago and couldn’t be happier! No more cycling batteries for long lawn projects on my large property!

Rated 5 out of 5 by from Worth EVERY Penny Purchased to use with my new trimmer/edger and blower, this one battery takes the the place of two smaller ones and actually does not weigh as much as its bulk would suggest. In the trimmer, it actually helps give counter balance to the unit. The added Amp Hours have allowed me to Trim, Edge and use the Blower and still have 2 to 3 bars of power. I live on a corner lot with a wrap around sidewalk and curb so there is ALOT of edging to do, not to mention the trimming and post mowing clean up. I am more than satisfied with the performance and power of the unit. The only thing that could bring down my confidence in this battery is if it starts having cell life or discharge issues. So far so good and with my experience with Ryobi Gas powered tools, I am hoping for similar results with the electric tools as my gas powered tools are still going strong after 8 seasons of hard work.
