    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 5436 reviews
Llegaron muy bien y cargadas listas para colocarse
This battery was half the price as a comparable battery from the local farm store and the same size, voltage, and composition.
I have used the Mighty Max replacement batteries in all my UPS’s for years. I’ve never had a problem with them being in use for at least 4-5 years.

Why pay more when Mighty Max is so reasonably priced.
Perfect fit
I am using these two 12V batteries to repack my 24V drop-in battery unit for my electric lawnmower. After installing the replacement cells I was able to try out my mower to my satisfaction.
Original battery had a problem and a new replacement was sent out. That's Great Service and excellent customer relations!!
This battery is for a Stanley Jump box. Perfect replacement. To help future customers I've included some pics of the replacement process. The battery is accessed via the back panel. Remove all the Phillips head screws (2 sizes) and the back panel to access the battery. I used an 8mm wrench to disconnect the wires on the battery.
Poseidon came properly packaged and arrives fast I purchased from Home Depot for my 2018 turbo s dual battery setup going to try these two batteries out and I'll keep you updated on the status and how long they last big system fast car running the dunes it's dune season let's go
Very Heavy Battery with excellent fit & finish. Arrived with full charge.
You receive this paper slip with your new battery- register online and receive an additional 3 months of warranty! You register online and then told - oh! you also have to post an online review with a photo to get those extra months! So, here ya go.
I ordered the batteries from Home Depot. They arrived sooner than expected. They were a performance replacement, and Granny is up and running the seats again!
