  1. Jordi

    The deep cycle marine grade battery was difficult to locate in my region since I’m not exactly near water. They’re useful for my solar gate opener and can be used for trolling motor or electric golf cart! The price is equivalent to auto zone/harbor freight. I bought the same brand compatible battery box with vent holes for extra weatherproofing so that I could use python locks to secure my battery to the gate and prevent theft.

  2. Jack McFarland

    The battery appeared to be a good value for the money. It arrived well packaged. It included the terminal bolts to screw into the female posts. However, one post was not threaded properly. Both bolts fit well in one of the terminals but neither fit well in the other. When I screwed it down the terminal top broke off with the bolt in it. I was very surprised but when I contacted customer support they issued a full refund/return. I was very pleased with this service. The battery otherwise seemed to be in good shape. As other reviewers have commented, the bolts were small and I would prefer a larger bolt size to use larger lugs to attach.

  3. Byron G

    This battery was a perfect fit to replace the batteries in a Pride Victory 10 mobility scooter (2 batteries required). After a full charge, the scooter was used for several hours at a theme park and performed very well.

  4. Michael J. Perkins

    Worked fine powering my trailer with a solar panel but this year it stopped holding a charge. Switching to a lithium battery next.

  5. Web Customer

    This unit is exactly as advertised. I have used it to replace the battery in my solar powered CPAP power unit. The product arrived sooner than expected. Very pleased with the price and service.

  6. Rita Rau

    All is good. Came with a warranty, quick ship perfect!

  7. Tony Vu

    Great battery, I used for running my font pump, 4 hours a day .

  8. iluvdrt

    This has been a great second battery for my camping accessories. This, along with a dual battery isolator works very well for all night appliances. Runs my fridge and diesel heater no problems.

    I run a small (24A) trolling motor on my Pit Boss boat. I ran this battery off and on for 3 days with no noticeable drop in output. I ran the motor on low, so I don’t know about charge life running it in high. Size, weight, and shape are great. I put one of my solar panels on the battery for a few hours and it was ready to go again. The only downside is that the terminals are small if the powered device has clips. I am very happy with this purchase. Love the gel, size, and weight!

  11. Jweiser

    good battery for the price

  12. F8Guy

    Perfect for my location video power. Works great with a trip-lite 300w power inverter.

  14. David and Tanya

    We needed a compact deep-cycle battery. The Mighty Max battery meets our needs well, and is a reasonable price.

  15. soaknewe (so can you)

    Installed this battery in each of my two driveway gates. Power for batteries are from a solar panel. Installed in Early June of 2020. Batteries are in a protected (from weather) container for the gate operators. I’ll update here if anything goes amiss. But so far, so good. Looking forward to see how they operate in Winter where we get into the 10’s. Update: December 2020. One battery won’t hold a charge. Won’t even charge to 12volts. Other one (bought 2) is holding up fine. Went to the Might Max website and entered a claim to get the defective battery replaced. Will let you know what happens. Stay safe.

    So far so good. I use 3 together to store solar power. Nice little battery.

  18. Daniel Jerchau

    Works well. I can’t rate longevity yet.

  19. Daniel Uitti

    I use this battery with my Solar panel. It is charged quickly. I use it in an Off Grid building for lights. As soon as I got it configured and insured that it had a 100% charge, I tested with full lights for 4 hours. With modest sun, it was recharged in 2 hours. With this confidence, I will probably add a few batteries, so I can provide power for 1000 Watts of 128 volts, so I can power small hand tools. for an hour or so.

  20. JayP

    Light and easy to carry to my boat. I use this with a 36 pound thrust trolling motor on a small aluminum fishing boat. I can fish 3-4 hours with intermittent trolling motor use without running out of juice. Generally it has 50-60% charge left after a trip. I can fully recharge it during the afternoon and go back out for a second fishing trip in the evening. Your experience may vary depending on size of your boat and amount you use the trolling motor. But for me it is perfect. Gel batteries have a longer life but make sure you have a charger that supports AGM batteries.

  21. neilsok001

    Right after it arrived we had a power outage of several hours. I hooked it up to my system, when the lights came back on, I slapped a meter on it again, very little change in charge. Next time I will hook up even more load and see how it goes. Up here we joke about the obligatory bi-monthly outages.

    Lightweight

  23. Anthony Capsalors

    I do not like the handle but for the money you can not beat it but you can count on THANK you

  24. Mr. Wonderful

    Utilized for a powerwheels jeep. Extended the run time tremendously!

  25. C. Fuechsel

    The battery appears well made, and I like the tapped terminals with supplied M5 bolts. Much easier to connect leads than with nuts and bolts. The description is confusing because it reads GEL AGM Battery. Well, these are two different technologies, with different charging requirements. Gel cell batteries do have glass mat separators as do AGM batteries, but I have never seen GEL batteries described as GEL AGM batteries. Technical information for this product is not available on the Mighty Max web site. But there is a specification sheet that I learned about from their parent company, and it took two phone calls to get it emailed to me. Reviewing the spec sheet reveals that this is indeed a GEL battery and the recommended float charge voltage is 13.2 to 13.4 Volts. You can cycle-charge the battery after a heavy discharge using constant voltage set to 14.2 to 14.4 Volts and limiting current to less than 10 Amperes. Note that these voltages are lower than would be used for a flooded cell battery, so only use a charger that has a specific program for GEL batteries. Failure to do this will likely damage a GEL battery. I have not used this battery enough to say anything about performance over many discharge cycles, but its a GEL so it should do well.

  26. Trevor

    Works as it should. I have bought 4 for my wheelers and have had no problems with them.

  27. Russell Ransburgh

    I charged it up but haven’t had a chance to see how it will hold up

    I purchased two of these Mighty Max 12v 35AH gel batteries and build a power station with solar charging for a week long camping expedition into the Colorado mountains. The batteries performed great. I can not find fault in their performance at all. My calculations indicate that they performed at or better then spec. Great quality batteries

  30. Pierre O Paquelier

    Seems to be good batteries and hold the charge Used them with solar panels and charge controller I have them for 6 month

    Keeps good charge

  33. SK

    I received my order quickly. I would have liked for the connections to be at least 5/16 instead of 10 machine screws. I guess I will find out if they can handle the current draw.

  34. T. D. Perry

    Perfect fit for what I needed it for – which was a battery box to use for a telescope. EDIT: Two years later and this battery is still running strong. A LiOn would be lighter, but I don’t think I’d get the length of running from then through the night with all my equipment that I do with this one.

  36. Gregg Roberts

    Running this battery in my Jeep as a secondary in a dual battery set up. Have a smart isolator installed. A 20w solar panel keeps this battery charged at all times. A bit smaller than a standard automotive battery. But that makes it easier to find a mounting location.

  37. Mark R. Gillean

    Excellent product and service

  38. 460 brent

    great product

  39. msr465

    Fantastic product I would give it 10 stars if it was available

  40. Chovis38

    I replaced my existing 20ah batteries with four of these in my hybrid lawnmower…. work fantastic, a definite upgrade. Good price and good quality. Fingers crossed these will last for years.

  41. Beer Boy1953

    Package was secure. Works as it should.

  42. B. G. Nguyen

    Good price, compact, and work as expected. However, it may be under power for certain uses or cloudy days.

  50. Jake

    The customer service is great. I will buy all my solar batteries from this company. This is a quaility product, fairly light weight and meets all my solar needs. I can’t praise the customer service enough. Thank you for sending me a great product in a timely manner. I have not one complaint.

  51. Julio C Collazo

    Got two of this battery’s for my Harbor Freight 100 watt solar kit, they work great, lot of power in a little package. Will buy more, thanks

  52. Frederick C. Johnson

    Perfect for use a field kit battery for my Yaesu FTM-100D amateur radio transceiver. Steady power, small footprint, relatively lightweight and well built. Paired with a good battery charger (I use the NOCO Genius GEN1), it’s a great combination.

  53. Boris Romanov

    Installed this Deep Cycle battery on December 2016, for my solar project (remote/on-site power for surveillance cameras). Battery still works without any problems even in a cold climate.

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
