Gravity is a tough law to break. Batteries and mechanical equipment are heavy, and must go where the floor is strongest. Which tends to be the core of the building. As always consult a licensed structural engineer. Protecting against an airplane crashing into the side of the building is hard (although the Empire State building survived). Pick your risks and mitigate those within commercial reason. Lloyds of London exists for the rest. Sometimes the best commercial solution is putting your equipment around the outside. You loose one rack of routers to wayward tree, a few customers are down. Loose your electrical plant, and everyone is S.O.L. Triage is never a pleasant experience. Another note about battery rooms in high-rise buildings. There is/was a proposal before the NFPA to prohibit battery rooms above the third floor in high-rise structures after the L.A. CO fire. I haven't been keeping close watch on it, but Bellcore/Telcordia was fighting it tooth&nail.
