Question UPS Battery Stuck

[IUseAComputer]

Hello. I need help replacing a battery in my CyberPower 1500VA UPS. There are two batteries, and I have the replacements. I was able to remove 3 of the connectors, but the 4th won't come off. The wire is too short to pull it out of the housing enough to work on it better. The connector will move side to side slightly, but that's it. With the cable cover, I can't see if it's corroded or rusted. Any suggestions?

The wire is too short to pull it out of the housing enough to work on it better.

There are battery replacement guides on the YT.

E.g CP1500AVR/CP1500C;

Just find the correct guide to your UPS and follow the video.

The connector will move side to side slightly, but that's it.

Battery terminal connections are one of the hardest to remove. (Akin to separating two MOLEX connectors.)

Just wiggle it left-to-right while at the same time, applying pulling apart force. Eventually, it comes loose.

Pull harder.

If it is a connection you can get to the wire, is a connector that you can replace, and are familiar with properly splicing wire you could attempt to lengthen and add a new battery side connector. F blade?
The other aspect would be to make sure there is room for additional anything to go back in the enclosure. Also KISS and make sure you are taking it out correctly as, things happen.
