5500mAh Battery Replacement for Ryobi 18V Battery P105 P108, Compatible with All Ryobi 18V one+ Cordless Power Tools

I own over 25 Ryobi 18V ONE+ tools, more than 20 batteries in various sizes, and about five different Ryobi chargers, so I’m very familiar with this ecosystem. When I saw these 5500mAh batteries on promo for around $18 each, I figured I’d take a gamble—and I’m glad I did. Performance-wise, they work surprisingly well. I’d say they provide about the same power as my Ryobi 4000mAh batteries, maybe just a tad less, but nothing noticeable for most tasks. For the price, that’s a solid win. That said, they definitely don’t feel as rugged or durable as genuine Ryobi batteries. The plastic feels cheaper and they’re noticeably lighter, which likely explains the lower cost. Still, they function properly, and at this price point, I really can’t complain. One important caveat: charger compatibility. Out of my five different Ryobi chargers, only three will charge these batteries. Two of my chargers flagged them as faulty and refused to charge them. So if you only own one type of charger, there’s a chance these may not work for you. Overall, these are a great budget-friendly alternative if you already have multiple Ryobi chargers and want extra batteries without paying full Ryobi prices. Just be aware of the charger compatibility issue before buying.

I was really surprised how well they've held up. Great buy for the price. Id buy again.

At first, I was not sure about third-party replacement batteries, but these PEYESTEN 18V batteries turned out to be very good. Since I often use Ryobi tools for my DIY projects, it is important for me to have reliable batteries and these are just right. First thing I see is how good they fit with my tools—no shaking or problems to connect. They work well with all my Ryobi ONE+ tools, like my drill and leaf blower. The 3.0 Ah capacity is big improvement; now I can complete whole project without stopping to charge again and again. The built-in LED lights are very useful. They show how much battery is left, which has helped me not to lose power while working on something important. These batteries also get charged fast and stay powered up for a long time, even when used a lot. I never had problem with overheating or overcharging because of the built-in protection features. It make me feel good to know these batteries are not just efficient but also very safe. Also, the one-year warranty make me feel relaxed, even though I think probably not going to need it! If you seek trustworthy and budget-friendly option to Ryobi-brand batteries, these PEYESTEN ones are very good. Strongly suggest for any DIY enthusiast or professional person!

great value. so far so good. works great.

The battery only worked for 45 days. After that the charger will not charge it and it says the battery is no good.

Batteries are still going strong months after continuous use. The price was awesome compared to name brand. Would definitely purchase again.

So much more affordable than the name brand ones, and honestly they work just as good. We have a lot of Ryobi tools and this battery snaps right in with no issues. The charge lasts long enough for our projects, which makes things so much easier. I love having an extra set ready so we never get slowed down mid-project. For the price, it’s such a smart buy and really keeps all our tools going strong.

It works fine with my Ryobi 18 V portable tools. We’ll see how long it last.
