                    I've been using the Ryobi One 18 volt tool system for probably 25 years, and have never had a single issue. The interchangeable battery system is fantastic and is simply reliable. Even though I have 20+ year old batteries in my arsenal that still work to this day, I added these because this bundle deal was too good to pass up. Highly recommend the entire Ryobi One tool system!

                    More power longer
                    I bought the high performance battery for our Ryobi vacuum cleaners. We use these for all the cat fir and the messes they make. The combo works better than the Kirby! The 4.0 HR battery has extra power for the higher vacuum level offered by the vacuum.

                      For the versatility to drill, leaf blow, super flash light, or even a portable fan to help keep cool in the Florida summer sun, these batteries are a game changer

                      Good battery life for high draw uses (mowing) pleased with battery life and price point. Bought as special offer in sale with free tool.
                      by
                      I have become a true Ryobi devotee. I now own five different Ryobi products, which meant I needed some extra batteries. Luckily, Home Depot was running a special where you get a free tool with a battery purchase, so I gladly took advantage and added another tool to my collection! Overall, I’ve had great luck with both the tools and the batteries. I highly recommend Ryobi products and will definitely continue to buy them.

                      These batteries work great! They last a long time and they charge really quickly. Works perfectly for all of my Ryobi needs.

                      Got a free 18V blower with this purchase. Our cleaner uses it to blow the dust from behind the couches.
