    Does not fit an APC BACK-UPS ES 750 without modification. If you dremel down the battery compartment fins it will fit after coercion. It is slightly taller than original RBC 4.

    I wanted to get my first impression here in case I forget to come back. I purchased this for my APC Back-UPS Pro 650 (BP650S) that uses a RBC4 battery, which this claims to be. It’s larger than a standard RBC4. If I feel like getting it out of the UPS, I’ll post measurements. I had to take the rubber feet out of the bottom of the battery compartment to close the door. I also had to to use a hammer to expand the compartment a little for the wires to not be stripped forcing the battery in. It powered up fine and just passed a zero load stood test. I’ll run a small load on it tomorrow

    This is a great battery that is easy to hookup and works great in my backup. It does what it is suppose to do. This battery is very light and fits great.

    Well priced and arrived on time. Seems to have taken a charge nicely and so far so good; time will tell if it lasts like the original.

These batteries were purchased for a razor motorcycle. They work wonderful and were easy to install! Our little man is happy to be back riding
Perfect fit and ready to go.
Arrived in perfect condition
2011 Yamaha Raptor 700R battery, started right up. Has a 1 year warranty. Great deal.
Love mighty max batteries
Arrived well packaged. No information as to original warranty coverage and term, but lots of solicitations to extend the warranty coverage for a whole amazing 90 days - Wow, such product confidence! At least it’s not made in China, but is Thailand any better for quality manufacturing? We’ll see.

Arrived next day and sas very easy to install. They also offer free 3 warrany extension.
I ordered this MightyMax battery through Amazon. The Ad states it works in my GE Simon XT house alarm.
I received my battery from Amazon on March 9, 2026. The box was a little squashed but the battery was packaged well and it it fine. I installed it and finally my gate opener is working properly. I purchased 2 batteries before this and had to return them because they were the wrong battery. This one is working great.
