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 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 Still going strong! I bought two of the hi-amp batteries and we use them at our auto repair shop with our impact wrenches. We didn't think they could keep up with the high demands and all, but so far they are just as hardy and strong as the competitor (Red) we use these Ryobi ones at about half the price of the competitor. We also go along time before we have to charge the batteries! I feel like I've found a secret that others don't know about yet and doesn't break the bank! Thanks Ryobi!

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 Lots of power Truly is high capacity. I can trim, edge and blow my lawn with just one of these batteries.

Rated 5 out of 5 by from Super run time. Excellent power Bought these back in 2012. Absolutely amazing. The yellow Nicads are a joke and ive rid myself of all of them, along with the dark grey litihium wana be's. They too also don't even compare to the P108. Runs my angle grinder like a champ for some time and I can cut quite abit of wood with the circ saw. I however dont think my spot light is very nice to the P108 as ive had 2 batteries die in it (one battery 2 years old and a newer one i bought this year.

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 3 out of 5 by from 18V one + lithium High Capacity Battery I purchased 2 of these batteries recently. They work great for the first 21/2 to 3 years but seem to go bad shortly after warranty runs out. I am a hobbiest so don't use every day nor expose to extreme loads or temperature changes. Follow manufacturers recommendations and leave off charger when not in use for long periods of time. For what they cost they should last considerably longer.

Rated 5 out of 5 by from Love the longevity and extra power. Purchased the 2 pack on Black Friday Nov 24, 2017 on sale at Home Depot. Prior to these i own 4 of the reg lithium batteries which have served me well since June 2013 and are still working like their brand new. The new high capacity 18V Lithium battery's are great. The added feature of the indicator lights lets me know when I'm getting low on power and the time to recharge them.

Rated 5 out of 5 by from great run time These batteries seem to run a long time compared to other brands I've used.

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 This battery changed the way all Ryobi 1+tools work, not only you get more running time out of you tools but the increase in power, speed and over all performance makes a huge difference, and the fact that it works with 50+ Ryobi tools it's amazing. Worth the purchase.

Rated 4 out of 5 by from More capacity and a charge indicator! So far, so good. I'm looking forward to not having to swap out batteries as often. I also like that there's a built-in charge indicator so I can tell whether or not the battery is fully charged before I use it. And it was on sale for the lowest price I've seen.

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 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 Used on high and it lasted 40 minutes, great We bought the weed trimmer, it came with this battery. The reviews said it would last 1 hour or less if you used the high speed. I used the high speed the entire time and it lasted 40 minutes. It never lost power until the battery was out of power. It is reasonably priced and light weight. I am a senior woman and had no problems. I highly recommend this.

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 Battery that lasts The Ryobi High Capacity Lithium-Ion battery is the longest lasting battery that I have used. It lasted a full 45 minutes while removing many coats of paint from a barn door with a coarse fiber disc and a lot of physical pressure. The Ryobi drill was working hard and was supplied by the High Capacity battery that kept going and going. Very impressive.

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!!
