APC SU48XLBP compatible battery pack

This two-pack supplies 12 V sealed lead-acid cartridges built to fit the APC SU48XLBP UPS. Each unit is a direct replacement for the original battery module, restoring backup runtime without modification. The set is sold new and covered by a one-year replacement warranty.

Replaces ageing or failed SU48XLBP cells

Swap the pack when the UPS reports a battery fault, runtime drops sharply, or the existing modules reach the end of their service life. The upgrade is worthwhile whenever the current batteries no longer hold sufficient charge to protect connected equipment during an outage.

Questions about this item

Will the 12 V cartridge numbered 11 slide into my SU48XLBP without modification?

Yes, the two-pack is built to match cartridge 11 dimensions so it fits the SU48XLBP bay directly.

What is the wiring step that causes a no-power fault on the SU48XLBP?

The two cartridges must be linked in series to reach the 48 V string; omitting the interconnect cable leaves the UPS dead.
