Great Reliable Product! I love my Ryobi tools run by Ryobi batteries, very reliable and always handy of any kind of jobs in and around my house and workshop. Batteries keep me going the whole day without additional charge. I just charge them up over night and they run the whole next day.

The Ryobi Sprayer is fantastic - so easy to use. It has made the arduous job of poisoning faster and simple, in fact it is a chore I now almost look forward to doing. The unit can also be used for spraying trees & bushes, fertilizing, and similar projects around the home. It also has a fitted measuring cap and adjustable nozzle.

My RYOBI batteries have lasted 4 years in my home garage. I have used them on all my tools, garden hedger, impact drivers, drills and reciprocating saw.
Good value. Didn’t need another tool so twin pack suited. Regardless of twin pack or a tool kit, was all around the same price ie $200, so rather than buying a tool kit with a battery and a tool I didn’t really need, the double pack was better. With the double pack I always have the option of going halves in the cost and giving one battery to a friend.
I purchased the 18V twin battery pack being very pleased with continuing to use our Ryobi products. The old battery (and only) was over 4 years old and performed well. After recharging, all products seem to now have a new lease on life. Better battery technology than 4 years ago? Anyway, very pleased.
Just purchased these extra batteries for my tools, they last so much longer and were such good value.. Ryobi stuff is so good 👍
Excellent products with quite a good lot of usage out of a single charge. I love the fact that you can use the batteries with such a wide range of products.
I’m happy with genuine Ryobi batteries. I have purchase no name ones and they do not perform as well and don’t last.
My 11 year old 1.3Ah battery was on its last legs after great service so it was time to upgrade! These beauties are a nice balance between weight and performance. Very happy with my purchase.
