    This battery was about 1/16 too big to fit in my APC BE750BB. I had to use a Dremel tool to sand down the thin ribs in the battery compartment in order to insert the battery. I would not buy again.

    Slightly smaller than the OEM battery which as it turned out is a plus. The OEM battery removal was a struggle to say the least. Chances are the OEM had expanded over time. The replacement with the new battery was a no problem. Also I like the fact that the batteries I ordered came with a full charge.

    Arrived in very short order and was swiftly lodged inside my UPS where it continues to function exactly like the OEM part five months later and counting. My Kill-A-Watt electricity meter reports precisely the same readings for both input and output current as I recorded when I first bought my UPS, so I have no reticence whatsoever in encouraging others to use this battery in theirs.

    I didn’t know the location of the seller until I got the invoice and shipping info – completely across the country from me. Since estimated delivery dates were rather wide spread, figured I’d have a wait. I ordered Sunday, it was shipped Tuesday – and much to my pleasant surprise arrived Friday via Priority Mail. Put it in the unit last night, saw to start with charge was at around 20% capacity – and short while I was on computer it gained 3%. This morning checked and it was at 100%. Now to see if it last the 6 years my original did.One problem not to do with the battery but with the unit design. The original battery was in so snug I just couldn’t get it out – had to ask a younger neighbor of mine to try – and with a lot of groaning and grunting he finally got it out. This new battery is exactly the same size – so it took more groaning and grunting to get back in. The fit is just too snug. APC could have just allowed 2-3mm leeway to make it easier to remove and install the battery. Other than that, very happy with it.

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.
