Vortech battery backup repair.


New member
Anyone have any experience with the older Ice Cap battery backup? It does not seem to hold a charge. If the backup itself is plugged in and I kill power to the pump it will switch to flashing green but if I then kill power to the backup everything shuts down after about 3-4 seconds. The backup hadn't been used in a couple years. Anyone have any experience with these. Is the a way to do dome type of diagnostic? If I open the case (it's riveted) should I look for anything in particular? Given that the pass through works I assume it's the cells and not wiring and I didn't think the backup had any circuitry on board. I guess it could be a wire for the charge lead. Anyway, thought I'd ask and give it a couple days before I open it up. Thanks
