This battery is a great replacement or substitute for any other smaller 12 volt utility battery. Same as others you need to watch your dimensions. I thought this battery would fit in a 5 million candle power spotlight I have, but it wouldn't. Instead, I decided to use hook it up to my 2500lb utility winch and make it a portable utility winch. Same as any other sealed battery, recharge after uses and you should get a good long lifespan from this battery.

Nice battery. The low profile makes it very convenient to use for just about any project. I use these weekly for many different DIY solar projects. The oldest Mighty Max battery I have installed is still operating as it should after 7 years.
I am very please with the size of this battery. A little wider rather than taller allows me to use this in places others would not fit.

We use this battery to power our rough cut mower that we pull behind our riding mower. It needs its own power source as it's completely separate from our mower and this battery does the job. It is a rechargeable battery which really works in this application. It is a 12V, 15 amp sealed battery. It is a compact size and will fit in many items that need a battery of this size and voltage (mower, electric start power washer, etc.)

I will be replacing my Alarm Panel battery with this Mighty Max 12 volt 15 amp/hour battery for backup when power is lost. This Mighty Max battery will give my alarm system nearly triple the amount of stand-by power than the battery that came with the Alarm Panel. This battery can also be used for UPS systems that are physically big enough to incorporate this battery. One can never have to much back up power !

The Mighty Max 12v 15Ah rechargeable sealed lead acid battery Is a good fit for my granddaughters electric scooter. While it is a little smaller in size it is perfect in voltage and amps hours. If it’s in the compartment with a little room to spare and the connector snap snapped into place easily. Since it came charged my granddaughter ran it around the yard until it died. Then we recharged it and tried it two more times. Going through the same cycle each time. The scooter is about three years old and it’s battery has been dead for about a year. This is the toy that my granddaughter really enjoys. By the way, she is five years old.

The MightyMax 12 volt battery is utilized in my enclosed construction trailer as power storage in a solar lighting system. The solar system was installed with a battery regulator to protect the battery against over charging. This isn’t my first Mighty Max battery. I’m confident this battery will perform and provide the same longevity and service as the previous unit.

Might max batteries continue to impress and this one has continued to live up to the hype. The price point with this battery is competitive at every level. Battery has a great charge and for me has outlasted the use of other brands. The Mighty Max battery works like any typical battery, you just charge it and it is ready to go. This battery will not leave in the dark lol pun intended.

Perfect for a smaller electric start generator, or, small side by side or Smaller CC 4 four wheeler or ATV. It DOES NOT have normal screw in Posts for the terminals, but it can be easily modified. It is a fully sealed battery and has a 15 amp hr rating. you don’t have to worry about Any fluid set up or making sure the battery sits level during storage. Well packaged for shipping. Would like to see a post adapter set for this unit.
This Mighty Max battery 12-volt 15 ah Rechargeable F2 Terminal sealed lead battery at first posed a little bit of a problem at first due to the F2 terminals which this battery provides. But after purchasing connectors at Home Depot under $3.00 dollars that will work with my system it was simple to make a small rechargeable system to perform simple electrical needs up to 350 watts on this particular setup. Until I get another Solar Charge Controller I will simple recharge this battery when needed by a battery tender which is running off one of my other solar panel off grid systems. This Mighty Max Battery works perfectly and recharge quickly and always ready when I need it. This one is of the smallest I have tried of their battery line but work equally as hard as the larger models. There are so may possible uses for this battery I love it and am sure it will last me for a long time. It never needs refilling of water and never leaks harmful gas which is perfect when stored in a shed such as I am doing for this application.

A great sealed battery for your high power needs.
After arriving just charge the battery and you are ready to go.
I use this in my fishing kayak for lights, sonar, GPS, radio and charging other devices.
It works perfectly and lasts an entire weekend of fishing with no charge.
This is also perfect for scooters, wheelchairs, anything that requires a 12 volt sealed battery with spade connectors.
See review pics for exact dimensions and power limits as posted on the battery.
Since this is a sealed battery it can be installed in any position you require.
Slow charge this for best long term performance, but it can be fast charged as well if needed.
