ML7-12 - 12 VOLT 7.2 AH SLA BATTERY - Mighty Max Battery brand product, black

This battery is a strong choice for providing reliable power in emergency lighting, alarm systems, or UPS units. I recently used it to replace an aging battery in my backup power setup, and it performed smoothly from day one.The battery is fully sealed, with no leaks or maintenance needed—just set it and forget it. At 7.2 Ah, it’s small enough to fit into tight spaces, but still offers hours of backup time for low-power devices. The terminals are sturdy and accept standard connectors easily, making installation quick and simple.One thing to note: like all lead-acid batteries, it works best when stored in a cool, dry place and charged periodically to maintain peak performance. Also, it’s heavier than lithium options, so expect a bit of heft when handling.Overall, the Mighty Max ML7-12 SLA Battery is a well-built, easy-to-install, and reliable power source. It’s a smart option for anyone needing standby or backup power without fuss or frequent upkeep.

​Based on reviews and price, I chose this compared to the actual CyberPower replacement battery. The specs are the same CyberPower RB1270B. I really wanted to find a LiFePO4 equivalent which should last much longer and handle many more charge cycles, but I couldn't find any that seemed proven over a period of time.I installed the Mighty Max battery and let it charge for over 24 hours (though I'm guessing that 8 or 9 hours would have been plenty) before testing the battery. It tests as having a 100% capacity and seemed to work fine.The proof of how good/bad the battery is will be over time. Being a standard sealed lead acid battery, I'm assuming it should be fairly average when it comes to battery life, performance, etc.

We use these professionally to rebuild data center battery packs for APC Uninterruptable Power Supllies. We've purchased over 100 in the last three years.They equal the OEM specs and are outlasting the APC factory units. On average we're getting about three years out of them before they need replacement, a year longer than the OEM batteries. That alone makes them a bargain.FWIW the gel cell version of this battery (as opposed to this model, which is SLA, sealed lead acid) is also offered by Mighty Max on Amazon. The gel cell's a little better if your application requires frequent deep discharge. For UPS battery packs, alarm systems, etc. this SLA version is fine.If they are shipped direct instead of by Amazon, you can expect fast delivery. The Mighty Max warehouse usually ships the same, or next day and they are packaged well.

Check the terminal size. The 4-pack uses the smaller F1 terminals, which are uncommon in UPS systems. F2 is the larger more common terminal. Mighty Max sent me some F1 Female to F2 Male adapters to use with my install, free of charge. But it took almost 30 days to receive them. Good battery & manufacturer / seller.

You don't know if these are no good until they don't work when there is a power glitch. I have had MANY UPS over the years from Cyberpower and APC, among others, and even those with battery condition indicator lights or in their LCD displays, they say they are fine and then pfft. This one worked when I put it in. I now put the date of installation and who I bought if from on tape on the battery

Worked perfectly. Had to conver terminals to 5mm holes in place of f1 terminals. Starts generator just fine

I used this Mighty Max Battery to replace the dead battery in my home alarm system, and it worked perfectly. Installation was easy, and the system powered up immediately with no issues. Solid performance and peace of mind—highly recommended!

The battery box showed the right dimensions however they were not! The CURT Battery Box is tapered towards the bottom from mold extraction and the battery will not fit all the way. I had to order a smaller battery the MP 1250 which is 5 ah and is smaller.
