Mighty Max ML100-12 12V 100AH Battery with Internal Thread Terminal

A Y G: 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...

Joan Rosier: I purchased this battery with a hope that it would eliminate low voltage issues I was having with my lippert leveling Jack's on my RV. Going on 2 years and I still run into issues almost every time I go camping. I have called lippert support each time and they are awesome.

The technicians have me scan through the readings to compare voltage from the battery and when hooked to power. Initially 13.7 with power, 11.4 when disconnected.

That isn't sufficient to operate auto level without triggering an error/fail. With my unit, front and year will communicate until level. Then the center jacks go down for stabilization. My last 3 trips due to fail codes, I never got to the finish line.

Hopefully I can get the manufacturer to engage and help me out. I am going to take the battery to AutoZone to get it tested. I often have to use my boat battery that is older to help me with my my RV connected or level.

Charles J.: Large heavy battery, about the size of a standard car battery, maybe a bit larger. It appears to be well made. Was fully charged when delivered, although it could stand to be float charged. I'm expecting five years usage, we'll see if it lives up to that expectation. Used in a UPS system for some computers running Linux. I have bought a number of batteries from Mighty Max and have always been pleased with their support.

Michael: I bought this battery and 700w PSW inverter to power a Jugs pitching machine. This battery is definitely overkill, I've run it for 4 straight hours and the battery still reads above 80%. Very heavy for my portable application

Buzzard Bait: 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!
