RYOBI 18-Volt ONE+ Lithium-Ion 4.0 Ah High Capacity Battery (2-Pack)

They are sill working. Great batteries for the price. The battery life is good so far. They fit well with all my Ryobi tools. I would buy again as needed.

These RYOBI batteries hold a charge really well and power through my projects without issues. Having two batteries is convenient so I always have a backup ready to go. Great value for the price.

My brother needed a new battery for our lawnmower that was running out of juice of the old one, and it works great for our lawnmower.

These RYOBI 18V ONE+ 4.0 Ah batteries have been excellent upgrades for my existing RYOBI tool collection, providing significantly longer runtime than the standard batteries that came with my tools. The high capacity really shows during demanding jobs - I can use my circular saw, drill, or leaf blower for much longer sessions without constantly swapping batteries or waiting for charges. The lithium-ion technology maintains consistent power output even as the battery drains, so tools don't slow down or lose torque like they do with older battery types. I appreciate the fuel gauge indicator that shows remaining charge level at a glance, helping me plan work sessions and avoid unexpected shutdowns mid-project. While they're definitely pricier than standard capacity batteries, the convenience of extended runtime and the 2-pack value make them worthwhile for anyone who uses their RYOBI tools regularly - the time saved not constantly charging batteries more than justifies the investment.

work well

Picked these up after the original small batteries my Ryobi drill and impact driver started to not hold a charge. I do not use my tools every day but I do use them here and there for around the apartment projects. I decided to upgrade to the larger size since I was getting new ones anyway. These definitely take longer to charge without the fast charger but not a huge deal for me. I did maybe 3 different projects with one of the batteries and when I checked I still had three out of four bars of power left. After doing research on the smaller batteries that went bad, I found out the voltage can get so low that the charging unit detects them as malfunctioning and does not want to charge them back up. I used these new batteries to essentially give a boost charge to the old ones to give them just enough charge for the charging dock to recognize them and start charging back up. Of course do this at your own risk if you try it. So now I have these two larger batteries, and I have the smaller batteries as back up or to use them with less energy intensive Ryobi products like a light to use while I am working on projects.

I made an attempt to get these batteries through Ryobi website which directed me to a Home Depot 40 miles away. I then tried using their OneTree online supplier. It took forever to get somebody to answer then the call was dropped. Going through Amazon was simple and easy.

Arrived on time was exactly as described.
