Batteries often used in battery rooms are the flooded lead-acid battery, the valve regulated lead-acid battery or the nickel–cadmium battery. Batteries are installed in groups. Several batteries are wired together in a series circuit forming a group providing DC electric power at 12, 24, 48 or 60 volts (or higher).
Generally, the larger the battery room's electrical capacity, the larger the size of each individual battery and the higher the room's DC voltage. Battery rooms are also found in electric power plants and substations where reliable power is required for operation of switchgear, critical standby systems, and possibly black start of the station.
The rooms are found in telecommunication central offices, and provide standby power for computing equipment in datacenters. Batteries provide direct current (DC) electricity, which may be used directly by some types of equipment, or which may be converted to alternating current (AC) by uninterruptible power supply (UPS) equipment.
Stationary type batteries, placed in special rooms used to generate direct current with groups of batteries in series or parallel batteries, in order to supply voltage and current appropriate with the specific needs of the plant.
Common applications of these batteries are UPS devices, alarms, toys, wheelchairs, and so on. The popular models commonly come in the form of smaller capacities, usually up to 30-35Ah, and normally come with a standard Group U1 and U1R batteries as the most common choices.
Separate battery rooms may be provided to protect against loss of the station due to a fire in a battery bank. For stations that are capable of black start, power from the battery system may be required for many purposes including switchgear operations. Very large utility batteries may be used for grid energy storage.
Ventilation is crucial for the battery room, as the standards listed above clearly demonstrate. BHS equipment ensures compliance with all relevant battery room ventilation codes — and, most importantly, a safer battery room overall. References: "29 CFR 1910.178 - Powered industrial trucks."
