Wondering if anyone has any experience or knowledge on these UPS Battery units.... basically like that size of a desktop computer tower. 230V input/output on them... i've found replacements for them but they cost a few thousand new... I have 3 that are not working, tried replacing batteries but that still didn't do it. before I scrap them for the batteries and parts i'm wondering if anyone has any info on a spot that repairs them or if anyone has had experience with these units?
