18V ONE+ Lithium+ High Capacity Battery is rated 4.7 out of 5 by 351.
Rated 5 out of 5 by from Ryobi One+ Battery Pack This was a combo battery pack at a great value!! The run time of this pack is pretty good and that is one of the main reasons why I buy Ryobi. The batteries are the first things to go out but this one has been hanging pretty good after I chopped up my Xmas tree, and branches from another tree. I then switched it to my drill to test its endurance and it held like a champ. Very happy to own the 6piece tool set with the 18g nailer! Looking forward to use the packs as we continue to build our One+ line.

Rated 5 out of 5 by from Great battery, long lasting The larger battery is a must for the larger tools. This battery last much longer than the smaller units.

Rated 5 out of 5 by from Long lasting battery! We bought this battery as part of a kit that included drill, hammer drill, saw, etc. My father has had the same kit for about two years and we were impressed with his. We started a project rebuilding our fence and these tools have been amazing, thanks to the batteries! Long lasting, they haven't failed us yet. Fast charging as well as having a button that lights up a charge indicator. In conclusion we highly recommend these batteries and tools because they won't let you down on your projects.

Rated 5 out of 5 by from power to spare! I bought this because they were on sale, two for $99, that is a great price. I needed the two of them to power my new Ryobi lawn mower, which works great to trim around my entire yard before I get on my rider.

Rated 5 out of 5 by from Great stuff In Dec. 2016, I purchased the 5 tool combo pack and really liked it. The tools were just what I needed around the house to get all of my jobs done, but the batteries that came with the set just were not up to the job as they did not last very long. I purchased the 2-pack of the heavy duty 4 Ah batteries. What a difference they made. They last longer and have so much more power and recharge in no time. And Ryobi is always adding more tools to work with the 18 + 1 system.

Rated 4 out of 5 by from Lets Try This Again I have purchased several roybi battery tools and even more battery's. To my dismay, they are going bad just after getting a year old. Mmmmm, but, my fault, I never registered for the battery warranty. This last purchase, and it will be unless something changes, I registered my battery and charger. Lets see how old they get. For convenience, they are great! Feel great in your hand, nice and balanced. Not too heavy. Here is to not having to buy another battery so soon.

Rated 5 out of 5 by from power to spare!!!! Took home the new batteries and started a project to redo a deck, used the new battery in my RYOBI 1 circular saw and found it did not stall out as the smaller batteries did then used it in the RIOBI 1 Reciprocating Saw also no stall out when cutting through nails. Next I used them i my RYOBI 1 Impact and Drill better power and never drained the batteries down to dead. Vry long lasting with power to spare. I will definitely buy more in the future.

Rated 5 out of 5 by from Longest lasting lithium battery and powerful I'm new into woodworking, and had been using the compact battery for my Ryobi 6.5" circular saw. When I put one of these monsters on it, I swear the blade revved up to much higher rpm and I could cut seamlessly for over an hour. Very impressed, and I'm glad I chose Ryobi when I recently bought my first set of tools. You can't miss with the 4 amp battery. Get one! The battery level indicator is a lovely added feature, but I rarely see the bars drop. Great.

Rated 5 out of 5 by from Long lasting After I purchased this, I wondered if the extra weight would be a problem. I put my high capacity battery in my drill after charging it and used it for drilling a few screws, but nothing extensive. Then I had to drill several holes in cinder block to mount pieces of wood. After several holes, the power was still there and I was able to finish the job. Honestly, I didn't notice the weight difference until I switched batteries to the regular one.

Rated 5 out of 5 by from Strong Handy Runner I bought two and have discovered how really good my leaf blower and weed trimmer are and how absolutely handy too. This battery revolution is great. Just pick the tool up and it's ready for immediate service. By having two I get all of my small jobs done in a hurry and the blower is keeping my other tools clean and ready just because it's so darn simple now that all's I have to do is push the switch and we're at work.

Rated 4 out of 5 by from Good Battery Haven't had it very long but seems to be good, replacing older batteries that I have had for a few years. The big test is going to be how long will they last, but the 3 yr. warranty is definitely a major plus. I have had my Ryobi combo set for like 10 or 15 yrs. and every item in the set are still working as good as the day they were bought and that is the reason I won't get rid of them for a new brand.

Rated 5 out of 5 by from Value I started with battery power tools when I purchased "dealt" tools many years ago. After having to buy a $100+ dollar battery several times during my ownership, I switched to Ryobi. The tools and batteries were/are less expensive. I have not come across a job that my Ryobi tools can't do. They are excellent tools for the money. The new lithium batteries make them even better and I got two to $99.

Rated 5 out of 5 by from Never out of power. I replaced a couple old batteries with these longer lasting ones and man I was surprised! When I changed to the small lithium battery it was nice but wasn't that much better than the originals. These ones not only last so much longer it seems like the tools are getting improved power. It may just be my imagination but I swear it's like I replaced the whole set of tools instead of just the battery.

Rated 2 out of 5 by from Wish it was better!!! I bought the double pack of 4.0 Ah batteries because the two 2.0 Ah batteries I had purchased previously did not last one year. (Note: register your warranty...I had not.) (and yes, I brought them in out of the freezing winter and charged them regularily). Now these 4.0 Ah batteries take at least 12 hrs to fully recharge. No "rapid" charge here. Hopefully they will last longer than a year

Rated 4 out of 5 by from I am very happy with the batteries. Good run time; quick re-charge. Used my Ryobi cordless tools to build a large shed and an even larger patio roof. One slight problem - 1 of the 5 batteries had a charge/recharge problem. Ryobi customer service was "okay" but could have been more helpful. Fortunately, The Home Depot saved the day and made a mo fuss, no muss exchange. Love the HD!

Rated 4 out of 5 by from Good Upgrade for High Demand Jobs Necessary upgrade for consistent DIY'er & part-time professional. At 4ah you get that little extra charge needed when finishing up your day. Light weight and equipped with "fuel" gauge so you know how much is left. Fade free power that lasts.. Only thing that disappoints me a little is the fact 4ah, when compared to competitor's, is still a little behind. Waiting for a Ryobi 9ah

Rated 5 out of 5 by from Long lasting! I purchased this battery a couple of months ago to have two for all the tools I have thinking I would need two to finish a full lawn job. I can trim and edge my whole lawn with the one battery and then use it to blow off the driveway, sidewalks and deck and still have some charge left. The 4 Ahr battery is great and only needed the one but good to have a backup!

Rated 5 out of 5 by from Ryobi Lithium Ion Batteries I got a two-pack of Ryobi 18Volt power tool batteries for a XMAS present and am very happy with these batteries. I had the charger already and these batteries work for a very long time on just one charge. Also they work with any other Ryobi tools besides my hedge trimmer and power drill. I would recommend these tools and batteries to others without qualification.

Rated 5 out of 5 by from Last a long time I purchased two of these batteries to use with my lawnmower and trimmer. Not only do they last a long time while I'm using them, they keep their charge for a long time after I finish charging them. I'm very happy with this purchase.
Date published: 2017-10-01
Rated 5 out of 5 by from Last Power These are the only batteries I will buy. They last, charge fast and meet all my needs. I have tried other lithium tools but nothing compares to Ryobi tools. Plus, they are always coming out with something new, which I buy. The amazing thing, they all use the Plus One 18V battery makes projects easy to complete. Just will not be without my Ryobi tools.

Rated 5 out of 5 by from Long lasting! I bought a set of these high capacity battery's last year and was very pleased with their performance. As soon as they went on sale this year I bought a second set. I have a small wood shop and use several Ryobi hand tools. I like them so much I have given all three of my sons several drills, saws and sets. Great line for my needs and at a fair price.

Rated 5 out of 5 by from Many possibilities!!! We purchased a double battery pack at a really great deal!! The weed trimmer that we purchased 3 years ago is still working great! Looking forward in purchasing your many other tools which use the 18 volt battery pack. The very new garage door opener looks a possibility for one our purchases here soon!! Great products with great accessories!!

Rated 5 out of 5 by from Love that P108 I now have 9 of them bought over several years. None of them have worn out where I need to replace it. The built in tester is a very useful feature. I use them on a mower, string trimmer, edger, and shear (considering a chain saw too). I maintain a small park in the neighborhood and a non-gas powered no maintenance set of tools is perfect.

Rated 5 out of 5 by from great adaptability I have been purchasing ryobi power tools for quit a few years now and am enjoying the fact that 1 battery will work with all . Some of the power tools drain the battery quicker than others but overall all tools are a great investment . I use my tools to build items and repair things and have never had a problem with the ryobi power tools .
Date published: 2017-04-29
Rated 5 out of 5 by from Lots of power I use my Ryobi cordless drill around the house and the battery is a great addition to the tool. It is the exact opposite of what I found with the old Ni-CD battery that came with the drill in it holds its charge in storage and seems to last forever in use. It is a great choice even if it is somewhat heavier than the old battery it replaced.
