6 Frequently Asked Questions about “Where are the lead-acid batteries in the computer room installed ”

Where should lead acid batteries be located?

Vented lead acid batteries shall be located in rooms with outside air exchange, or in well-ventilated rooms, arranged in a way that prevents the escape of fumes, gases, or electrolyte spray into other areas. Ventilation shall be provided to ensure diffusion of the gases from the battery, to prevent the accumulation of an explosive mixture.

What type of battery is used in a battery room?

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).

Why do datacentres use lead acid batteries?

Initial Purchase Price: the greater the runtime of the UPS, the larger the battery set. This is one reason why larger datacentres install only a 10-30minute battery and use a standby generator for longer autonomies. Lead acid batteries can be up to 70% lower in cost than than a comparable lithium-ion UPS battery.
