    I was pleasantly surprised to get this ahead of the time it was promised. I am replacing the original battery in a 15 year old jump box.

    I needed a replacement for the battery in my portable vehicle jump starter (the original battery was finally dying). This was the closest I could find (slightly higher capacity) and the dimensions listed were slightly larger than the original, but I figured I could make it fit. It arrived well packed and protected, and when I checked it against the original battery it was exactly the same size. I installed it, charged it, and it has restored the operation of the jump starter to like new.

    Ordered as replacement battery for my cordless mower. Much cheaper than if purchased original brand, yet seems to hold the charge very well and to put out pretty good power for an electric mower.

    I bought it as a replacement for a NAPA jumper box. Exact fit, put it on charge overnight and used it the next day. I saved at least $75 by replacing the battery rather than a new jumper box. Totally happy with it.

    Time will tell, but so far so good. I bought a pair of these for my APC battery backup. The OEM batteries tend to go five years or more so I’m hoping for the best. The dimensions were right on and they were fully charged out of the box.

    Batteries brought new life to my mower and it became all powerful – well at least enough to comfortable mow my entire yard. The batteries came in good shape and well packed; they fit exactly in my Black and Decker cordless lawnmower; and they work great. I need to find out how to recycle my old batteries for free and it would have been nice to have received four strips of foam tape so the stacked batteries didn’t clatter and vibrate against each other.

Excellent
Mighty Max Battery
Based on 3434 reviews
Ordered from Amazon it Arrived fully charged for my grandsons ATV for Christmas it's already wrapped so this is the best picture I can do at this time.
The batteries arrived on time. They were securely packaged. I especially appreciated that they arrived fully charged. I was able to install them immediately.
Mighty Max reported to alarm backup duty today. I have always had long life from Mighty Max.
Fit perfectly.
So far so good I bought it for my 99 Sportster XL 1200 S I've only had it installed for a day and I've been riding the bike all day long made half doesn't stops and fired right up no problems every time keeping my fingers crossed it stays like that for next year or so
Perfect sized battery for my atv, I’ll update my review as time goes
Unloaded and installed. It fired right up. Thanks a lot !!
If you want great batteries at a great price, look no further than Mighty MAX on Amazon. I will definitely purchase again.
Battery arrived packaged well and in great shape. I just got my deer corn feeder for Christmas. I did plug it in and made sure it worked great. I will not start using it in Sept of 2026. So looking forward to a better and easier way to feed my deer during season next year.
It's good quality, I just need to try it out. I bought it at Home Depot.
