  1. Nick

    Not sure how long are these batteries suppose to last, but mine is dead in 4 years. Used for my home security system.

  2. Caesar Acosta

    Great product , it works as expected, I used on a Battery back up Chamberlain garage opener with no issues. Great price compare to the regular hardware store.

  3. Dennis Bentley

    Worked as advertised. Thank you.

  4. Barbara L

    Replaced a defunct battery backup in my home security system. Don’t know what the longevity of this battery will be, but previously I was getting about 5 to 6 years of battery life. Priced reasonably and fit right in existing enclosure.

  5. Web Customer

    perfect replacement for my spotlight

    Working great for my Honeywell Vista 20P from Protection One. Existing connectors on the panel popped right on. It is lower capacity than what I had originally from the security company but I’m not too concerned and it’s no fault of this battery.

    Its pretty simple. …your battery died on the alarm system…The security company wanted $$$$$$ to come and basically replace a battery. …Great buy…saved serious $$$$$…no brainer plugging it in…works fine ….will definitely buy again …

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
