ML5-12 - 12 Volt 5 AH, F1 Terminal, Rechargeable SLA AGM Battery

Just installed. Works well. Used a YouTube video to learn how to install in UPS. Works well and saves dollars. Avoided having to purchase a new UPS at more than twice the price.

This was a perfect fit for my APC Back-UPS 425. Why toss a perfectly good UPS, when, for a fraction of the cost of a new UPS, you can replace the battery and have a like new UPS? U-Tube videos provided all the instructions I needed to quickly change out the old battery with this Mighty Max ML5-12-12 volt battery. I've used Mighty Max batteries in a number of applications in the past and have been happy with the fair cost and performance of this brand. Glad it is available on Amazon. Local salvage yard will pay me to dispose of the old battery, so you can't go wrong with this one!

The battery in my Genie 7055 Garage Door opener failed after about 4 years. I was able to remove the original dead unit and replace it with this one in just a few moments. The replacement fitted comfortably in the space that the original took, and the F1 connectors snapped on with ease I tested the backup without any power being applied and the door opened slowly, as it should, just on battery power. The mains power is now connected, and everything is working as before. I can't comment on life, but so far this battery seems like an excellent low-price substitute for the OEM battery.

Got this for a garden sprayer that we outfitted to use as a portable waterfed for window cleaning. Old battery wasn't holding a charge after six years of off and on use. Battery is exactly as described. It was easy to install. Works just like my old one when it was new. Definitely plan to order again whenever we need any more.

Used in Chamberlain garage door opener. Battery seemed to do everything it was supposed to and fit perfectly. It failed after just under 3 years. Side split open. Guess I couldn't expect more for the price.

Great price! Easy to install, fully charged. My ion block rocker works again!!

I was greeted at my garage door opener last week with a fault that my battery back up needed replacement. I did a quick search and found that my big box retailers had them but they were kind of expensive. So I looked on Amazon. Glad I did. This was a perfect fit for my Craftsman garage door opener. IT was exactly like my original. Easy replacement. Perfect match and it appears that it will provide the same level of battery capacity. I purchased one to see how it went before I ordered the second one for the other door. Now that I know that it's perfect, I will order another one.

I just installed this Mighty Max battery into my home security system as a direct replacement for the exact same model. If the performance of the last one is any indication, I’m set for a long time. What I like about it: • Proven Longevity: My previous Mighty Max lasted a solid 5 years before needing a replacement. In the world of security backups, that kind of reliability is exactly what you want. • Perfect Fit: It was a seamless swap. The dimensions and terminals matched the factory specs perfectly, making the installation quick and painless. • Value: For the price, getting half a decade of "set it and forget it" performance is a bargain. It’s great to find a brand that remains consistent over the years. If you need a dependable backup battery that won't quit on you after a few months, I highly recommend this one. Highly recommended for home security backups!
