Purpose-built backup power

The APC SUA48XLBP is a 48 V external battery pack rated at 1632 VAh, designed to extend runtime for compatible Smart-UPS units. It uses maintenance-free sealed lead-acid chemistry with suspended electrolyte for leakproof operation. The pack is built in a tower or rack-convertible form factor measuring 17.5" x 8.7" x 19.5" and weighing 146.00 lbs. It ships as a single 91065L assembly ready for integration.

Voltage and capacity match

The single specification that decides fit is the 48 V DC output combined with the 1632 VAh rating. Only UPS models designed for a 48 V battery bus and this capacity step will recognise and charge the pack correctly. The supplier data lists compatibility with APC Smart-UPS SUA models rated at 2200VA and 3000VA. Connecting it to a unit with a different DC bus voltage or capacity expectation will prevent proper operation.

Runtime extension limits

At 1632 VAh the pack comfortably handles extended runtime for the listed 2200VA and 3000VA Smart-UPS models during typical loads. It runs out when the connected load exceeds the UPS inverter rating or when the discharge duration surpasses the pack’s stored energy. The sealed lead-acid design delivers a service life of three to five years before replacement is required. Buyers needing longer autonomy than a single pack provides must add further compatible units.

Questions about this item

How long will the 1632 VAh capacity keep my Smart-UPS running?
