If the UPS has only a single string, taking the battery out of service for cell replacement (i.e., possibly requiring that the UPS be switched to bypass) puts the critical load at risk. The owner might decide that full replacement makes more sense than enduring multiple downtimes for remedial maintenance and cell replacement.
UPS batteries should never be installed outdoors where they can be exposed to the damaging effects of sunlight. IEEE 1635/ASHRAE 21 is a good engineering reference for designing properly ventilated battery rooms and cabinets. Lead-acid batteries contain substances that are not good for the environment in which we live.
Open-rack battery rooms must be adjacent to the UPS room. Battery cabinets must be adjacent to the UPS equipment. Cable lengths from multiple cabinets should be kept as nearly identical as possible to prevent voltage drop variations. One cabinet should be able to hold at least one complete string of cells.
Smaller UPS systems (e.g, up to 250 kVA) are commonly installed directly in the computer room along with their respective battery cabinets. The UPS and/or battery cabinets might be configured to look like standard computer equipment racks. There are two primary hazards of concern: electrical and fire.
