Long story short, I recently came in to enough money that I was able to properly build and connect two high-end gaming machines (one for me, one for wife/step daughter) and I'm wondering if the ESD from a vacuum cleaner can negatively affect a battery backup system. Once, a while back, she was vacuuming near a computer that was sitting mostly on the floor and running, and the vacuum actually popped the PSU right there. Since these battery backups also sit on the floor, it just occurred to me that the same thing could happen. Or could it?
