    • Great Replacement Battery for my Basement Watchdog backup Sump Pump
Edition: 12V 75 AH

A great replacement battery for my Basement Watchdog backup sump pump. I replaced on old lead acid battery that was on the system with the new Mighty Max AGM battery and it worked like a charm and was $50+ cheaper than the other alternative. Installation was a breeze and took me less than 5 minutes, the battery fit perfectly on the shelf. It is a heavy battery so the built in handle to carry it was extremely useful. Just a note for anyone using this battery on their backup sump pump, if you had the old lead acid battery with a probe, just attach the probe to the positive terminal along with the power wire and it will stop the audible alarm!!!! ... show more

    • Used these to replace the 75AH batteries on my RYOBI riding mower
Edition: 12V 100 AH
Unfortunately I learned that my original 75AG batteries that came with my RYOBI riding mower were failing. I struggled through a final season, mowing just a few minutes at a time. The following spring, there was just no denying that I needed to do something. I considered lots of options. Many people are even upgrading to LifePo4 batteries. I decided to not go that route for a couple of reasons. 1) Cost. These AGM SLA batteries are half the cost. 2) I learned the early demise of my batteries was probably partially due to user error. I ran mine down more than 60%, which I later learned is a big no no. 3) People who hadn't done what I did were still running their original batteries 6 years in. 4) While the other upgrades look cool and all, I think the verdict is still out on their longevity as well. 5) The tractor was made for these batteries, so installation shouldn't be difficult while other batteries may required some modifications. 6) I can still use the OEM charger, so I don't have to get a new charger. 7) Even if I have to replace them again in 3-4 years, I can get another whole set of these and still be at the same price that the LifePo4 upgrade is today. So if I LifePo4 gives you 10 years as people claim, these could give you 6-8, or if like the person at 6 for their original batteries, maybe even 12, for the same price. 8) The LifePO4 could be cheaper in a few years. 9) I may want a new mower anyway in less than 10 years. 10) I chose to upgrade to the 100 vs the 75 because of learning running below 60% can damage the batteries, so for only a little more, you have more margin. So, I am not saying you shouldn't switch to LifePo4, but these are some of the reasons I chose not to jump on the Bandwagon. Once I had decided not to, I needed to decide what to get. I chose to get these for a couple reasons. 1) They were significantly less expensive than the brand that came with the tractor 2) While some brands were more affordable, multiple other people had used these and seemed to be having good success with them. 3) They were readily available, in stock, and I had them in just a few days. 4) I am familiar with MightyMax, so I am not too concerned that if something does happen, and I do need a replacement, that I will be able to get one. The installation went smoothly. The battery tray on the tractor is made to fit these batteries, since it was an option on the tractor when it was sold new. I simply pulled out the battery tray. I let it rest on a mini sawhorse. This was the hardest part of the whole thing for me was thinking of a way to support the tray when it was in the out position. I then removed the old batteries. I expanded the battery spacers, since these batteries are larger than the 75ah batteries that were removed. In order to get the locking part that holds the batteries down to the tray, you have to move the front spacer as far forward as possible, which involves removing the inner bolts. Put everything back together the way you found it. Charge them up with the original charger. Cut your grass. Repeat I have had them installed a few weeks now and everything is working great. I have about a one acre lot and I don't even use one bar on the battery meter to cut it most times. If the grass is really tall, and a little wet, and I cut it really short, I might use one bar. The tractor works like it did the day I rolled it off the crate. Right now, I am extremely happy with the choice I made. Highly recommended. ... show more
