I’m trying to replace the battery in my mom’s APC BN4001 UPS, but the red wire that connects to the battery won’t come out (the black wire came out just fine). Would using a pair of needle nose pliers be a good next step or should I try something else? Should I just look for a replacement UPS? I’ve never had a problem swapping batteries in the past, but this thing will not budge.
I’d ask APC but their support is M-F.
