    My, now antique, wired alarm needs a battery for back-up power. These batteries need replacing about every 5 years or so – at least that has been my experience. According to the specs this battery is rated for a slightly more max amps but apparently that is OK with the alarm as I unplugged the old battery, plugged this one in (two bayonet connections – just keep the + & – straight) and the alarm is happy again. The battery sits in a large metal box so slight variation in size is OK but this one seems to be (by eyeball) the same size as the old one. (Old one was a UltraTech UT1240, 12V 4.5AH I bought at the local battery store.)Only time (years, hopefully) will tell how this battery stacks up to prior ones in terms of durability.

    hoping this last for the warranty period which is longer than most you can find locally. good value. easy to order, and delivered as promised. nice to not have to drive to make special trip to the few motorcycle batteries are available.

    As a replacement battery for my home alarm system. It only took 1/2 hour for it to reach full charge and is now running the system as its supposed to do.

    Great battery, far more economical than purchasing locally

  19. Rated 4 out of 5

    My Opinion –

    Quick delivery from Mighty Max. Good packaging.Looks OK outside. I have charged it with an external charger (Noco) and installed into security box. Give 4 stars because it is impossible to tell how long it will last which is the main criteria for a battery. I have fios battery that is still operational after 6 years and another one that failed after 4 years.

    Bought this to back-up my Comcast cable so that my house phones still work during a power outage. Didn’t work. Hard to tell if it’s even charged. There were no instructions with this battery.

    Battery replacement was an exact size fit and no issues to date. Only time will tell how good a battery replacement really is.

    I loved this battery! It provided me with so much power. It’s so… full of 12 volts that my alarm is happy again when the power goes out. I’ll cherish this battery until it dies, then I’ll recycle it and buy another. Just like that.

    Charged it on a battery tender, then plugged it in, and it worked. Not much more you can expect or ask for in a battery. We’ll see if it’ll last 5 years.It has made it a couple months tho.

Mighty Max Battery
Based on 5437 reviews
A+ my second time buying these batteries
Exactly what we needed.
This is an awesome Mighty Max battery and came fully charged and works great. I’m very happy with my purchase. Thank you.
Hi looks good
Just replaced A battery for my jump box I will see how it works out! I did have to drill bigger holes in the Terminals for the bolts so far these batteries have been excellent for everything else lawn tractors, generator Battery

New battery for emergency lighting excellent!

Second battery for my second classic Exide emergency light!
And another one for my second emergency light

This one is going in on Bluetooth speaker in my garage
This is the second one I bought in less than a year, and they both have worked great
Perfect replacement for the factory original, at a lower cost.
Got new battery faster than expected, for lawnmower. Came in a box neatly packaged. Charging for 24hrs, light is on, meaning it's charging correctly. Can't wait to turn it on.
I ordered these babies off of Amazon. Since I'm not sure how full they come, I have them installed in the scooter box and in a maintenance (opposed to trickle charger, which I recommend), and will do a test run tomorrow if no rain. Great reviews convinced me to buy these. Plus being manufactured by a US company was the other deciding factor. Also my brother bought these same 24 V/ 15 Ah Mighty Max batteries and he's mid-way through year 4 with no noticeable power loss on his scooter. No brainer.
Works as it should.
