    So I was pleasantly surprised when Mighty Max sent me another battery on their own volition to fix my terminal problem. The NB terminals for the new battery is oriented exactly as pictured (the original battery that was sent had the terminals oriented parallel to the width of the battery and not parallel to the length of the battery as pictured). I will give it to Mighty Max, very surprised that they listened to comments here on , and made things right. I’m changing my rating to 4 stars, and will update after i install the battery.

  11. Lenwood –

    This battery was an exact fit replacement for the Stanley 700. It came with new bolt& nuts for the terminals and it arrived 90% charged. An easy and inexpensive replacement.

    this was a great option for a replacement battery in my Clore Automotive Jump-N-Carry JNC300XL. it was a bear to reroute the wires and get it closed again, but that is no fault of the battery. saved me from spending $86 on a new jump pack, and saved me quite a bit over the oem replacement battery as well. thus far it has performed as well as the original battery, but im not running intense tests on it or anything. it was installed in feb 2020. if it wears out or fails, ill update this review, but so far so good!

  13. Ron B –

    Bought this for a portable General generator. It fit perfectly and had plenty of power to start the generator.

  14. Jim –

    Like size for my portable generator.

  15. Deborah –

    Perfect fit for my jump starter. Terminals are a little short but it worked fine with the included hardware.

  17. David Alexander –

    Great price and fit.

  18. Rick S –

    The terminal bolt holes need to be altered in order to attach the wire ferrel.

  19. George Covert –

    Battery fit perfectly. Up and running.

  20. Nancy Gorres –

    battery works great but I had to modify the cable terminal ends from the generator because the terminals on the battery were sunk in too short to fit the cable ends,they should spend more time & money on mfg & quality control,maybe less on advertising. on the plus side,i was impressed with inventory&quick delivery.none of the local generac dealers stock a battery!

  21. HunterClan –

    The battery came quickly. When we put it on the generator, it had a pretty good charge on it. I would buy this product again.

  24. Sergei Pepper –

    Is doing great he did better than the original battery that came with my booster pack the booster original battery lasted a month that was it

  25. Adran T. Hanson –

    Looked locally and all I found were batteries set up for slid on clips. I needed bolt on. This was perfect. Generator fired right up.

Purchased a small battery for my pop up camper, I have a heater and it draws 3 amps so I discarded the very heavy battery on the draw bar and added in this 18AH battery to run the heater and LED lights, works a treat for 61-8 hrs, weight only a few kg compared with 20+ for the old battery, I would add another if we had higher draw and run in parallel. Overall a very tidy battery that won't spill as it's a SLAB

Needed a new battery for my ever dependable ATV. So I wanted a dependable battery. From the first start, you can feel the cranking amps turning the 325 cc motor. Day after day,same feel of power. Gives me peace of mind when deep in the woods or plowing my long driveway. Maintenance free factory activated gell battery also !!Thanks MIGHTY MAX. YTX14AH-BS. 210 Cold Cranking Amps
