Ease of use is one of the principle selling points for battery cabinets. It is convenient to service the equipment when the UPS and the battery (ies) are right next to each other. Conversely, it is inconvenient to have to go to a separate room when open-rack batteries are installed.
Because cabinets can have locked doors, the cabinets do not have to be in battery rooms; they can be installed directly adjacent to the UPS system and/or the information technology equipment. This eliminates the need for long dc cabling. Battery cabinets can be made to be indistinguishable from IT equipment cabinets.
In our introductory unit we pointed out that lead-acid batteries are the preferred method of energy storage for UPS systems in about 95% of all data center applications. We also stated that lead-acid batteries can be split into two main categories or technology types: valve-regulated or vented.
Valve-regulated lead-acid (VRLA) batteries can be mounted on racks or in cabinets. The remainder of this paper will address considerations for VRLA placement. Size Generally speaking, the larger the battery (both physically and ampere-hour rated), the more likely a rack configuration will be considered.
Battery cabinets must enclose the batteries behind locked doors accessible only to authorized personnel. As long as the cabinets are kept locked, they can be located in a computer room or other rooms accessible by non-battery technicians.
Re: Lead acid batteries in a confined space -- Any lead acid battery which includes flooded, gel and AGM batteries, will evolve H2 and O2 if overcharged too much. Sealed batteries use recombinant technology but are valve regulated, meaning that they will vent if the internal pressure exceeds the set pressure.
