  1. Jesse C.

    Great fit for my Security Alarm

  2. Steven

    Direct replacement for my home security system.

  3. SteveO

    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.

  13. R. W.

    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.

  14. genius

    So far so good in the alarm system.

  15. Michael Maurer

    Works exactly as advertised. Couldn’t be more pleased.

  16. A. Cohen

    The battery arrived on time, works great. It does exactly what it’s supposed to do. let’s see how long it lasts.

  17. Aubrey M.

    Different brand name but was same size and terminals. Seems to be working fine.

  18. Jeffrey H. Taylor

    Great battery, far more economical than purchasing locally

  19. 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.

  20. Pakitullanc

    Arrived today. Swapped it with the dead CPI battery. Works good. Time will tell

  21. Jill D.

    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.

  22. Fields

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

  23. Joel M.

    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.

  24. HR

    Very good and cheap

  25. Customer

    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.

  26. Deb G

    Arrived on time, fit right in, works great. what more can I say about a battery? It does what it’s supposed to do. let’s see how long it lasts.

  27. Mark

    work at advertised. Good value. Plugged right in as a replacement.

  28. Tim

    This was a direct replacement for my Ademco alarm system battery. The dimensions were accurate and the battery arrived before the stated delivery date. Great seller and product.

  29. Francine Galante

    Works with my alarm system

  30. Eugene Godefroid

Mighty max brings the battery backup back.
Arrived well packed in unopened sturdy box. Was replacement for identical Mighty Max battery I ordered 2 years ago. Taking 1 star off because didn’t include the needed terminal clips - was able to use the old battery’s clips
Same model fits in each of our four wheelers great product
Replacement for my Murray MT100 riding lawnmower. Murray does not make replacement batteries and you are on your own if the battery goes bad. Bought Murray MT100 in 2023, battery went bad in 1 year and all other Murray replacement batteries are LARGER so it won't fit.This Mighty Max Battery fit the MT100 fine and it starts it perfectly too.
Direct replacement for generac portable electric start generator. Works great.
Received really quick. Boxed well and fit great. Worked like a charm! I would definitely recommend this battery.
As an athletic trainer I rely on our water units every day to provide the water to our athletes. We have over 900 student athletes enrolled, and these units get used daily, so it is imperative these batteries are reliable. On a side note, I also use these batteries on my fishing kayak to power my fish finder. I can use my fish finder for about 20 hours before it turns off. These batteries are great! Highly recommend. I have not had any issues so I haven't spoken to customer service yet, but if they are as good as these batteries have been, I think I am in good hands.
Needed a replacement battery and the manufacturer wanted $50 whereas you only required $20. Made it worth it!
satisfy with price and easy installation.
Arrived in great condition comes with the bolts to attach the wire over all very satisfied
