      Q:I bought a new battery OP4040A1 to replace the old OP40401 which was only charging to one out of 4 lights. When I connected the new battery to the OP404VNM charger, I got the error lights flashing. The same result with a new OP403VNM charger. Why?

          Does not fit my 40v ryobi chainsaw
          I would have thought all 40v ryobi batteries would fit all their 40v tools. Nope, doesn't fit my 40v ryobi chainsaw.

            Battery only lasts 20 minutes
            With one battery it takes me 3 days to mow my lawn because I need three full charges to finish it. Run time is 20 minutes or less on one full charge. Ridiculous. Going back to gas after I sell this mower.

Runtime will vary depending on multiple factors, such as outdoor conditions, grass height, and grass thickness. Would you please send us an email at Reviews@RYOBItools.com?

              Product doesn’t hold a charge. Don’t buy!!!
              This is my 3rd Ryobi 40-volt lithium battery and they don’t last, which is crazy considering the price you pay. Frustrated! I love the Ryobi line of Expand-It products and have several accessories-but they all need batteries. We have a large property so battery products work best. Ryobi needs to fix the product flaw or find another provider to make them if they want to retain customers. I do not recommend buying this battery until Ryobi can make a better one to offer its customers.

                Perfect fit for my Ryobi 40v tools
                [This review was collected as part of a promotion.] Works great on my Ryobi 40V weed trimmer and blowers!

                      40 volt, battery
                      This battery is terrible. Only lasted 2 summers and know is completely dead. The battery cost 179 dollars which is ridiculous. I may as well go buy a different leaf blower, it’s cheaper

                        Defective Battery Problem After Minimal Use
                        This battery comes up defective when charging and really doesn’t hold charge very long. Not impressed that I’m expected to pay a couple hundred for a brand new battery unless I want to break the warranty and attempt to charge the battery myself. Will not be buying again as it’s apparent these batteries aren’t built to last.

                          [This review was collected as part of a promotion.] This battery never lets me down! I keep two 40v packs charged up and swap the out if I overwork! This keeps up with a hard working man!
