    It is larger than the designated room inside. BUT this room is made of several thin plastic tabs because 425 box itself is huge inside. Soooo…. For those lamenting that it’s too big, doesn’t fit, fraud etc – take pliers and twist-break a few tabs. Place the battery as it was – with contacts to the side, and see which tabs need to go. Grab the tab and twist, it will break. Takes 30 minutes if you are not mechanically inclined, 5 minutes of you are capable. Fits tight and neatly in the same position as the original battery. Pros – few times cheaper than the correct battery. Cons – you have to do some work. No worries, next battery will likely be same big.

    Slightly bigger than old battery. I just had to break a couple plastic retaining spacers and then the battery fit right into ups case. It charged up and I tested it to make sure it works when the power is cut off. Alot cheaper than buying a new ups. The plastic spacers were easily broken in the ups case with a household pliers.

    Update:The supplier: Mighty Max Battery, reached out to me and sent me a replacement battery, which definitely does have a better run time. I have changed my two star rating that I had originally gave the item, to a 5 star rating. Not so much for the product, because that still may be a hit or miss issue but 5 stars for their customer support/service.The battery’s fully charged run time is not very long, in fact, this replacement battery (Mighty Max) last as long as the dieing original 8 year old Toro battery it replaced (in a weed whacker). I was hoping that a few charging cycles would improve this issue but so far not yet. Not all that happy with the Mighty Max Battery.

We needed a replacement battery for our Game Day Speaker. I chose a Mighty Max 12V2.9Ah battery from Amazon. Ordered and had it here in 2 days. The battery arrived in perfect package and fully charged. We installed it in our speaker and are now ready to use again. Super Great Price! Will definitely use this company again!
Ordered a bundle of Mightymax ML5-12 to replace batteries in my 2200 va kvm. They fit well though the terminals were smaller than the batteries I'm replacing. Test worked fine and I'm satisfied. Thanks MightyMax!
Pleasantly surprised, battery arrived fully charged. Made it for a quick install!
Great experience with Mighty Max Battery. I use the ML35-12 Gel model for my MightyMule electric gate, and it’s a perfect fit. The shipping was fast—arriving a few days early—and the packaging was solid, with high-density cardboard and styrofoam protection.

The battery arrived fully charged at 13.06V and provides reliable cranking power even after the gate has been sitting. I also appreciated that the terminal hardware was included and securely attached. High value and great performance; I'd definitely buy from them again.
Quality product at a great price and received promptly!
Arrived next day, can’t wait to install this on my SSR Bison 200p. I have had so many issues with the 12v atv batteries.
Hope the battery works as good as it looks
Great deal on two of these batteries. Packaged extremely well. Put one on my generator and it started right up.
Works great installed easy and come pre charge.
