    • Well packaged in two layers. Came just about fully charged. My application is a large UPS.
I'm using it for the pellet stove, boiler and modem and router so the genny don't need to run 24/7. Contrary to other reviews, this is rated for a 27 Amp charge but the harder the charge or discharge, the shorter life it will have. Also, the deeper the discharge, the shorter the life. It's just the nature of this 1980's AGM technology. Still, in their element, they are excellent. It came with super long bolts---like maybe 25 mm!---so a 300 Amp ring terminal is no problem at all! Safety Note: Ensure that you use a fuse to protect your wires in case of a short since the SSCR is an insane 1800 Amps! ... show more

    • Used these to replace the 75AH batteries on my RYOBI riding mower
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

    • Good value, fir in Ryobi 480zx Mower
Review Image by todelady todelady
Good quality and value. Replaced the 12v 100AH Leoch batteries in my Ryobi zero turn mower - ZT480EX. They are the same height and width, just a little shorter so no problem as a replacement. The terminals have a smaller diameter screw but the work fine with the existing terminal lugs. A very easy replacement, just space them out appropriately. They also work fine with the existing Ryobi charger. Registering gives you an additional 3 month warranty. ... show more

    • Good battery.
Battery arrived fully charged, Install battery to my sump pump And have had no issues. Only complaint is the battery was delivered and set on my porch upside down. It does prove that these batteries do not leak.

    • Inconsistent charge state, but in spec, packed well, and should work well after charging.
Order two together and they both arrived at the same time and in good physical condition. However one battery read 12.89V (good charge state but not a full charge, maybe 2-3 months on a shelf). The other was low at 10.73V (borderline charge state, probably on a shelf for 7-8 months). These should both charge up matching voltages and work well in a 12V parallel system. Took a star for the mismatched age/charge state of the batteries. Ordered 2 together expecting to get a pair of batteries that were of the same age. Within days or weeks of each other not months apart. If the batteries don't work out well I'll update this review. Update 1/28/21 Weak battery exchanged with no hassle. New battery was in good condition and I now have the pair tied together in a battery bank. If voltage check was done before shipping, this would have been a 5 star review, and avoided the exchange. ... show more

    • Defective
Batteries do not work and smell like rotten eggs. Contacted manufacturer and was told to get a refund from where we purchased. Attempted to replace or refund thru Amazon and was told to contact the manufacturer.
