Compatible UPS Models

This battery pack fits the SRT1000XLA, SRT1000XLI, SRT1500XLA and SRT1500XLI Smart-UPS units. It supplies 48 V DC power to keep those systems running during an outage. The pack is designed for network administrators and small-business IT managers who need reliable backup for critical servers or network gear.

Thermals Noise and Power Draw

The sealed lead-acid cells are spill-proof and maintenance-free, producing no audible fan noise during normal float operation. They accept a steady charge current from the UPS without generating excess heat in typical office environments. Low self-discharge keeps the pack ready for extended periods between discharge events.

Build Quality and Mounting

The enclosure measures 21.1 in x 3.4 in x 17.0 in and weighs 82.0000 lb, housing two lead-acid batteries in a black metal chassis. Hot-swappable design allows replacement without powering down connected equipment. Multiple packs can be chained together to increase runtime for longer outage protection.

Questions about this item

How is the SRT48BP battery pack installed and what step is often missed?

The pack slides into the UPS enclosure and connects via the built-in DC plug; the step often missed is securing the front mounting brackets before powering on.

What maintenance or replacement will the SRT48BP need later?

The sealed lead-acid cells are maintenance-free; plan to replace the entire pack after three to five years when runtime drops below your load requirement.

What limit appears first on the SRT48BP during sustained discharge?

The 48 V DC string voltage sags as the lead-acid chemistry depletes, so the UPS low-voltage cutoff triggers before thermal limits are reached.
