          Mine did not come with screws/wing nuts or any hardware. What size screw do I need to buy? Manufacturer phone number does not work and I cannot find the information online. Everyone gives conflicting answers.

                    Using it as backup for our sump pit; working perfect so far, no problems. Arrived quickly and in great condition.

                    Good delivery time
                    Purchased four of these on 05/11/23 for my Ryobi RM480 mower to replace the original 75 Ahr batteries. Now on 05/04/26, two of the four fail a load test and run times have fallen to twenty minutes. Routine depth of discharge for these batteries is 9.05% with 140 usage charges and 108 storage charges. That’s not a good life span based on the 9% RDOD. The good news is the mower has saved $425 over the cost to operate a comperable ICE mower. I wonder how long the remaining two batteries will last? The original batteries lasted five years and were showing signs of degraded performance. I expected the larger 100 Ahr batteries to last longer with the same usage. Maybe it’s time to convert the mower to lithium power like the other four RM480s on my street have done.

                      Functional & operational
                      The unit came on time, well-packaged & without any visible damage. Once installed, it took the charge & maintained it, as it should, for as long as the charging cycle begins again (for a sump pump backup application). So far, so good ...

                        Perfect Replacement For Ryobi OEM Batteries
                        Replaced the 4 OEM 75 ahr. batteries with these 100 ahr. units. shipping packaging was excellent and the new batteries charged great with the Ryobi charger. Replacement took about 3 1/2 hrs. and required no modifications to the mower's battery tray. Performance is better than when the mower was new.

                        A non-starter
                        I ordered 4 of these to replace the failing batteries in my Ryobi Riding Lawnmower, which has only 53 operating hours on the batteries. Unfortunately, although the batteries appeared to be in good physical condition when they arrived at my door, using a battery tester proved otherwise. All four showed they were to 100%, around 12.7 volts, but the internal resistance measurements, were all above 75 mOhms, and the tester indicated the batteries needed replacing. Returned to HD.

                          My husband had to remove the handles from the batteries to fit in our zero turn. They charged up fully with a couple of cycles and now work great! He is so happy to mow the whole yard at once. We are very happy with our purchase!
