## Description

Product description

Review: High quality batteries .... truly outstanding US customer support ... and a HUGE tip on ordering - I've bought several of the Might Max batteries over the past few years. They've been used in everything from kid's ride on tractors to alarms to UPS devices. Actually bought this one as a replacement in an APC BE550G. Most people check the length, width, and height of the battery before they order it. But you also have to PAY ATTENTION TO THE TERMINAL SIZE !! The APC BE550G is a perfect example of why that is true. Apparently APC, in its infinite wisdom, produced different versions of the BE550G. Some came with connectors for F1 terminals on the battery and others came with connectors for F2 terminals on the battery. An F1 terminal is 3/16" wide while the larger F2 terminal is 1/4" wide. They are NOT interchangeable. I made that mistake and learned the hard way. If your UPS has F2 connectors, they will NOT correctly attach to a battery with F1 terminals and vice versa. The terminals on the UPS and the battery must MATCH. Might Max is very good about telling you which size is on every battery they sell. Some reviewers have blamed Mighty Max for the fact that the battery they ordered was not identical to the original APC battery. Do NOT blame Might Max, the problem was created by APC. To make matters worse, desertcart does not accept returns on batteries if you discover that the battery you ordered has the wrong terminals. But all is not lost. Might Max is a rare company in the desertcart world. They have a New York based customer service center that actually answers the phone and is ready to help you solve any problems you run into. In my case, they offered to send me two tiny little F1 to F2 adapters for free. Seriously, what other company would ever do something like that for you? They send them by US mail so it takes about 10 days for the terminals to arrive, but hey ... they're doing you a HUGE favor here. One the adapters arrived, they fit perfectly, the battery dropped right into place, and worked like a charm. So, don't hesitate to use Might Max batteries, they're top quality. And please do yourself and Mighty Max a big favor by double checking the size of terminals/connectors you need ... smaller F1 or larger F2 ... BEFORE YOU ORDER. Just because Mighty Max will help you get out of a jam ... let's not abuse their good nature.

### ⭐⭐⭐⭐⭐ Good battery

### ⭐⭐⭐⭐⭐ Great APC BE550G Replacement Battery!
*by A***P on October 7, 2025*

Perfect fit for an APC BE550G replacement battery. It was very easy to install. The connection wires fit into the terminals and snapped into place creating a secure connection without any issues. Other reviews mentioned that the F1 terminal was not the correct size and that it should be an F2 terminal but the connection was just as secure as the original OEM battery. Priced at around $20 for this large 7.2AH battery is a great deal. We purchased a different Mighty Max battery for another APC UPS a while back and it has worked perfectly. Solid quality product at a great price. I'll update this review if either of the Batteries stop working.
