So Far So Good!
This is my second Ryobi battery and they work great with my mower and vacuum. They also don't take very long to charge either. A bit pricey but I think they are worth it.

    Battery failed
    Purchased a Ryobi weed eater about 1 year so I've only used it about 20 times. Battery on it completely dead now. I asked Home Depot they said I have to mail it back (at my expense / time) to Ryobi and they will replace it. They sell just this 4Ah battery for a small fortune and I'm certain it comes from China for about $10 USD. Ryobi needs to have better quality control over their Asian factories. Now, I'll never buy another Ryobi product with a lithium battery.

          Love my Ryobi 40V System
          I have converted to using all Ryobi battery driven products around my home for garden, yard care, and power tools. I was sick of spending money on gasoline powered yard care tools for edging, trimming and hedge trimming that constantly broke down. Since moving to the Ryobi 40V system, i have not had to repair the drive system a single time. I have heard complaints about how long the batteries last on a single charge but i have not seen the problem. I have 1/2 acre with fences, raised beds, garden, driveway and roadway and I dge every week. It takes me 1-1/2 hours to complete all of it and i do it on a single charge. I have a second area that is 175 ft by 15 ft around a group of trees that must be done separately but even it is done on a single charge and it takes two passes to complete. I recharge my single battery between doing the main yard and the area around the trees, which takes about 1-1/2 hours. While the battery recharges i mow the rest of the yard. These new systems have saved me trips for gas, mixing gas and oil and the storage. And oh yes i have tried the 4 cycle engines too and they last just the same as the 2 cycle- no thanks! As long as you have access to a charging station, ie. you are not working out in the woods somewhere, this is the way to go. Recommend these to my brother who had rotator cuff surgery and he is super pleased. No more pulling stater ropes for gasoline engines and less risk of reinjuring his shoulder. I also use this system for my hedge trimmers, garden tiller, blower, and edger. The only way to go!

          One season battery
          The battery works great for the season, and then when you charge it in a few months, it won't charge. I can't afford to buy a new battery every spring!! I have a weed eater and blower. I guess I need to buy a new weed eater and blower that's battery will last as long as the warranty!!

            Good capacity, shows remaining charge
            I'm using this battery with the Ryobi 40V leaf blower and it holds a good amount of charge. The battery will also show the remaining charge when you press the button on the front face which is nice.

              Garbage battery
              I bought this battery as replacement for the defective battery that came with the mower. Neither battery could completely mow my front yard which is small. Mowing a fifth of an acre should not take days to do. definitely ditching Ryobi products from now on.

                Good News/Bad News - and a word of caution
                Bought op4050 (5 amp) model because my 2-year old 2.6 amp battery would only run chainsaw for 15 minutes. Charged my new battery overnight and it ran for... 8 minutes! Good news is that warranty 800 operator was friendly and is shipping me a new battery. Bad news is still have to wait two more weeks for a decent battery. Date code incidated battery was produced 15 months ago. This again confirms lessons I have painfully learned about Ryobi batteries. If you buy from anyone other than Home Depot, Ryobi WILL NOT honor a warranty. It sucks how expensive these batteries are, but bite the bullet, but from Depot, and keep your receipt and order number for the full three years.

                  awesome 4ah Bettery for ryobi.
                  Awesome battery. Made way better then older one of 40 volt. Same setup as old but newer is better. Bought it for the 40 volt power source pack. Will use on outdoors too. Charges fast and fits snug in power pack incase of power outages.
