Can a battery be installed horizontally?

Models installed horizontally may not be mounted on the end (shortest side), should not rest on the cover or case/cover seam, and must be supported fully on the long side of the case. Use caution not to cover or apply pressure to valves located on the top of the batteries when using strapping to install or secure cells as damage may occur.

Can a VRLA battery leak acid?

Does laying a ups on its side work?

Laying the UPS on its side works only until someone else goes "wtf is this" and "fixes" it. Don't do it. It's an accident waiting to happen. Orientation-wise, laying the UPS on its side works for the batteries, but it is awkward, takes up space, and also blocks some vents, so I don't think this is reasonable.
