  1. Dawn Austin

    This review is for the battery @ ~C10 rate to a reasonable discharge point. For anyone who doesn?t know when they rate batteries they rate them at the C20 rate and to a depth of discharge that spells certain doom (short life) for batteries. To rate batteries in this way isn?t really fair however it is the standard industry practice to get the ?best numbers? that you possibly can. To put it simply if you cycle this battery how its rated it will NOT last long.Luckily here comes this review with some more realistic numbers for you. This test was conducted using a fan that pulled 3.65 amps of current (roughly C10) as indicated at the shunt. This fan is running on an inverter (to simulate a real load) and since the battery voltage decreases the current increases during the test to a maximum of 4 amps by the end of the test. This simulates real life because standard loads require a set amount of energy to function and if the voltage falls the current must go up. Simply your devices don?t care the battery is dead and still want their power. There are no free rides.If you want your lead acid batteries to last you should never discharge them below 11.6 volts (under standard C10 load) and you should recharge them as soon as possible if you want the most life. In an emergency there is more capacity in the battery however you will be damaging the battery.My Findings:Capacity @~C10 rate to 11.6 Volts = 22.07AHStart of test 9AM End at 2:40PM = ~5.75 HoursDischarge Rate 3.65 amps @ Start – Constant Watts~265 usable wattsFor my uses this pairs nicely with a 100 watt solar panel.In short can this battery actually do 35AH?? Maybe however I’m not going to ruin mine to find out. It will likely do 22AH for 1000+ cycles though. I will update this review through its life.

    i gifted my grandson with raft and motor….This batteryy great

    I bought this to add to my overland trailer I have three in there now I run them parallel. So I went recently on a week-long trip with my overland trailer. I do have a goal zero that I use as well but I mainly worked off of these batteries. I was able to run my lights as normal I have a lot of lights lights in the rooftop tent, lights underneath the rooftop tent. Lights in the awning and different lights around the trailer It’s mainly what I use it for and all is well as my water pump that runs the water.I was able to last a week with three batteries and still have 40% battery life at the end of the week. I charge my phones my camera batteries just about everything I’m very pleased. Overall I’m very pleased it worked flawlessly they hold the charge really well I haven’t charged back up the batteries yet they’re still sitting in the trailer as it gets cold outside and it holds the charge as well It’s still sitting at about 43% from what the meter says.

  4. Sue Patrick

    This is working great for the trolling motor (from Walmart) for my Kayak. It lasts quite a while. Most the day on low. A couple hours on high.

  5. PCH Camper 101 Life

    Good value!

  6. Customer

    good stuff

  7. Karen

    I’m am 68 years old and wanted a lightweight battery for my trolling motor. This item fit the bill.. Works great for my purposes.

  8. Mary E. Petty

    Bought this battery for my electric gate – very lightweight and easy to install. Depending on how long it lasts more than likely to purchase again.

  9. elena zaltsberg

    Very convenient to install and works perfect with the generator

  10. Sean Hayes

  11. MC Rockstar

    Light and easy to install.

  12. Terryutica

    Working like it should

  13. QuadFlyer01

    So far, this has been an excellent battery!

    Bought 2 a couple of months ago and now they die very quickly and will not hold a charge THESE ARE CRAP DON’T BUY..

  16. Customer

    i purchased this as intent to be a power back up for my basement sump pump on the cheap. I connected it to a trickle charger and the sump pump. It had the power to run the sump pump but not for long. The trickle charger never fully charged the battery and was always beeping of low charge. I returned it and got a full refund in less than one minute through chat. i didn’t have to return the battery d/t hazardious materials.I never got the oppurtunity to test the quality of the battery out, therefore I can’t speak of the performance or longevity. It just wasn’t a good fit for my sump pump.I will update this review if a larger 120 ah battery has the same complications to rule out other variables.

  17. Wocket P

    Haven’t had these batteries for long, but so far so good! I finally found a battery box that will fit both of mine so I can run with 70Ah. Plenty of people on the internet that have run into the problem that they are just 1/8 too wide to fit sideways in standard marine power boxes. Having them in a box makes it easy to combine them into one on my bigger boat, or split em between my two smaller boats by pulling one out. The model of the box is HM306BKS

  18. Kody Kuhlers

    The battery arrive quick but was not exactly as described, same dementions but not what is pictured. Product was received with a bent terminal, I reset the position with an open face wrench. I have not tested voltage and have not owned it long enough to test longevity.

  19. David T.

    Arrived pretty much fully charged, No issues, a good buy

  20. Tiim

    I like the fact that this battery includes rating data and performance curves. The ones you get from the local stores do not, and especially comparing with Harbor Freight, you are getting a better quality battery from .This battery is an Sealed Lead Acid AGM type. Relatively high Ah rating for the price, but compared to Lithium Polymer or more expensive derivatives, the AGM low voltage cutoff for 10% life left is about 11v vs 12v for LiFePo. This means less run time on high current devices, like communications equipment. To be fair, LiFePo is nearly triple the cost, so, for me, the AGM is the winner.

  21. Braeden

    Biggest battery I could find (Says 36 AH in the engine manual but could only find a 35 AH) that is recommended for the Predator 670 engine. This is used to start it and also run LED lights + an hour meter. No problems here and there is no alternator on the engine either. Just the factory charging system which is low amperage.

  22. BG

    We’ll see how long it lasts….

  23. Michael R Martin

    I can keep it charged with my Auto Battery trickle charger.Don’t have to recharge very often.

  24. J. Zenkus

    Running an off grid solar hydroponic farm. Had a couple smaller AGM batteries that ended up getting flooded so replaced them with this single bigger one. Arrived a day early and it was fully charged. Double boxed, no damage. Does come with hardware (looks like 1/4 bolts) which is good because my old hardware rusted from the water.

  25. Customer

    Value

  26. Jerry L.

    Fit my craftsman riding mower perfectly – the power poles are opposite from the traditional battery but the new bolts and cables fit fine. Started right up!

  27. Guy Ellis

    Bought this battery to troll my fishing kayak. On low speed it will troll 5 hours plus. 10 foot kayak 32 flp minnkota. Very happy.

  28. Jim branham

    Worked great small tracker !

  29. JORGE TORRES

    They arrived charged and ready. Used for about 6 hours up and down hills. Function as they should.

  30. Bigbluoblk

    Perfect

  31. Go Vols

    Easy replacement for 10+ year old John Deere LA110. Amazing to get this shipped to my front door for free. Thanks.

  32. JJ

    On my fourth battery from these folks now and they are perfect for smaller scale solar projects. I have 2 18AH and now 2 35AH Batts. The latest 35 battery has a newer handle but the same dimensions.

  33. bill

    Great quality compared to the others on market and packaged nicely. There are three different trays that make it easy to get the color you need quickly without having to dig and search for the right color tone or shade

  34. Randy Rhoades

    Starts my 2020 Suzuki 20hp outboard.

  35. Domino

    Great battery for the money. Prompt delivery and great descriptions of size and weight.

  36. Robert H.

    Was good for my father in law scooter they were fully charge and drove 2 hours then took charge. Charge lasting very long better then the battery plus batteries that were in it

  37. Customer

    Used insole powered sin with two 10 watt lights. Will run the lights for at least three days without sun. Only in service for a month so don?t know about length of life.

  38. Andrea

    Arrived in beautiful condition and at 12.87vdc. Love the post size and design. I will run charge cycles and update on longevity. Hope to be ordering one a week.

  39. Rosa Lee Ryan

    Works perfectly as a replacement battery for my sliding gate! Very happy with it!

  40. Customer

    Works great. In use it to start my 13hp Honda motor. My motor charges while it runs. Used it all summer and haven?t had to recharge it yet.

  41. Michelle Gulden

    Does what it says

  42. Scott M Richards

    Attached a 12 volt outlet to it and plug my cpap into the outlet. I get 4 straight days of using my cpap for 6 to 8 hours a day and there’s still 60 to 70 percent left according to the battery charger.

  43. SailorHarry

    This battery is a good buy–no core charge. I am using it to power a 12 volt air compressor to power the air brakes on my train club’s passenger and conductor cars. Two full days of almost continual running discharged the battery–far longer than I had hoped it would work, so I am very well pleased. The battery accepted a full recharge and it is back in service. As far as longevity, only time will tell. I have had some SLA’s fail in under a year of very light use to over three years with heavy use.

  44. MntnMom

    I purchased this on the recommendation of several sites and reviews suggesting it would fit the Goal Zero Extreme 350 as a replacement for the original battery.While it is the same width/length as the original battery, is it slightly taller which means that the bracket that holds the case together absolutely will not fit around it, and the battery isn’t returnable. Wish I would have checked that before ordering.I can’t speak to the quality of the battery specifically, so I marked it as 3 stars.I just wanted to share this in the hopes that I might save someone else the trouble of paying for a non-returnable battery that won’t fit.

  45. Paul Hicks

    2nd one I bought lasted about 6 years so I bought another.

  46. James

    Perfect size

  47. Lee Jenkinson

    A very nice heavy duty battery for a good price.

  48. G

    great value, performs well under extreme weather conditions

  49. Funbuyer1971

    Made a great replacement for the standard batteries that we’re on our chair

  50. RollinRonin1

    I bought these for a power chair. Been great so far.

  51. Greg

    This is a smaller footprint battery, both from a size and energy footprint; however, it powers my 36 Minn Kota trolling motor excellently. And it is so much easier to carry around. If I saw myself going out often, I would be inclined to buy a second one to provide more power across a full day of being out on the water.I would give it 4.5 stars only because it does operate on par (duration) with a regular marine battery and the price was a bit higher than expected as compared to full size marine battery.I am very glad I purchased this battery.

  52. Jane A.

    Great

  53. T. J. Garrett

    Works good so far only used for a couple of months now but so far so good

  54. Mario Andy

    After one month of service with a 100w solar charging system this battery is still working great. My application almost completely discharges the available power daily, and it is holding up well. No noticeable heat is produced with my 6 amp load continuously applied.

  55. Glen E Thomas

    Need to power a few devices while camping, looked at larger batteries but determined I wanted a reasonable priced power station that was easy to carry by one person. This battery is the perfect size and capacity to allow me to run a 12 volt fan and lights while camping. Easy to install in my battery box and provides plenty of power for an entire week of camping.

  56. Jessica Warren

    Works great for our raft boat haven?t had the battery die yet

  57. Marine7089

    Good battery, very strong output. Will revise once I?ve used it more.

  58. E.S.J.B

    I purchased a used lawn tractor and the previous owner installed a battery that was far too weak for the purpose it was being utilized for. I purchased this battery as a replacement and the difference in performance has been night & day. Starts right up with no issues every time and feels more solid and well constructed over cheaper big box store batteries. Time will tell the true story, but thus far I am pleased.

  59. Daniel

    This is my second set in three years. You can’t beat the price and quality. Used in a mobility scooter. Under heavy daily use and these batteries have never failed

  60. kenneth fortner

    To start my generator

  61. Joseph Daley

    Great batteries for the money

  62. Quenstin Helms

    Great product

  63. Customer

    arrives very fast works well

  64. teddy

    great awesome thanks!

  65. bob

    I use this battery to power a Minnkota endurance 45 trolling motor, my average fishing trip usually lasts about 4hours. With the motor running a a low speed constantly, it gets me home with plenty of charge stilling that battery. The size and lightweight of the battery is a great feature for an older guy like me and the price is also outstanding. Highly recommend

  66. Sam-I-Am11

    Solid battery

  67. Ira Callahan

    Easy to use.

  68. Rob. S

    I live on a small electric only lake, so I rely on a decent battery for my 14 foot fishing boat… or I am stuck rowing.This battery has lived up to my expectations. When coupled with the minnkota battery box, I can easily see when I need a charge. It lasts what I deem an appropriate amount of time, I wouldn’t say forever but I can definitely use it for several hours of drive time before it needs a charge.About 6 weeks after owning the product, one of the battery terminals broke. I’ve never seen this happen on a battery before, but this made my battery useless. I sent a note to the seller on a Monday, and by Saturday my new replacement battery had arrived in the mail.

    I purchased this battery as a replacement for the original manufacturer sealed battery in my Goal Zero Extreme 350 power station. I was a little concerned after I ordered it because the battery terminals are different than those on the original Goal Zero battery. Even though the terminals are vertical versus the original battery that had them in a horizontal presentation, this battery works well. It was fully charged and the company provided new terminal screws, washers and bolts. I used the original bolts (because they are shorter) but the nut and washers from this kit. All in all a good fit and replacement for the original Goal Zero Extreme 350 battery.

  71. Customer

    When you pay $30.00 and up for a tractor battery that only lasts at the most 1-2 years, a $60.00 investment for a battery that lasts around 6 years, NEVER leaks acid everywhere, and works when standard batteries DON’T, the BEST money you will ever spend is this Top-Quality, Great SEALED lead-acid battery!

  72. john hartley jr

    Bought this for my professional pool vac a PV 2100 and it fits in the waterproof case just perfectly. Couldn?t be more happy with this and my other mighty max battery I bought for my multi tool jump starter for cars.

  73. jaz

    Works perfectly for my kayak

  74. Michael Schledorn

    Love this battery!

  75. Ruslan Khusniyarov

    I bought four of them. Working perfect.

  76. C. Schwartz

    I use 3 of these batteries in my small pond boat to power my 45 foot pound Minn Kota Endura Max. I was using one Type 31 battery that weighed over 60 pounds. It was a beast to get in and out of the boat every time I launched it. So I went with 3 of the ML35-12 batteries hooked in series with clamp cables. BEST thing I ever did. These batteries are excellent performers. No regrets !

  77. Charlie

    The battery works just fine

  78. S. Schnell

    Very long lasting batter. I’m using it to drive my Minnkota Powerdrive 40. It is super light and very small compared to normal deep cycle batts. Highly recommended

  79. Customer

    Exactly as represented. Charges easily and fast. Holds the charge well.

  80. Jimmie

    I haven’t been able to use it yet. It looks like it will work for me.

  81. James F. Lenski

    Did everything I wanted it to do!

  82. ALG

    Well Made Solid Product

  83. david bolt

    good price and free shipping, they are very strong batteries. they really last a long time in my mobile scooter

  84. Like it is

    Would purchase again.

  85. Seanne West

    My husband loves his new battery…pushes his 2 man boat around with ease!!!

  86. NS

    While I like this product and is small and affordable, I feel like there are better batteries out there for the money. I did a lot of research beforehand, so I will save you some time. If you are purchasing this for trolling motor, know that it will only power the motor for about an hour, depending on the thrust of your trolling motor. Since trolling motor amp hour usage at full speed pretty closely mirrors the thrust output, a 35 ft lb. thrust motor will only last about an hour with this motor. I have a 50 ft lb. unit and so I would only get about 40 minutes out of this battery. Costco has batteries with double and triple the amperage for only about 15-25 dollars more. Also keep in mind that they charge a 15% restocking fee and do not cover return shipping. Not that happy with this product or the overall experience. Wish the listing would have talked about the restocking fee…

  87. Reggie Hudson

    works like i need it to

  88. john daye

    fantastic battery. light enough to carry. provides plenty of power. if you want more amps, buy two or three batteries. i have bought four of these 35 amp batteries.

  89. Aanthony

    I my self have bought 5 different mighty max battery’s. The first thee I got for my golf cart, and I was very happy with them but they where lower amps per hour,but work great so I just bought the one with 35 amps per hour and took out of the other ones and replace it,so now I have around 75 amps per hour now and they last longer now. Even with the first three I had got I ran 3 days on them. I just didn’t know how much amps I needed cause I took out 6, 6volt battery’s.
