Description
APC Smart-UPS SRT External Battery Pack — 72V, Extended Runtime for 2.2kVA
The SRT72BP is an external battery pack that extends the backup runtime of compatible APC Smart-UPS SRT on-line UPS units. Where the SRT's internal battery delivers minutes of runtime under typical load, attaching external battery packs extends that to hours — critical for environments without standby generators or where transfer time exceeds the standard runtime envelope.
Compatibility
- APC Smart-UPS SRT series at the 72V battery voltage
- Compatible with 2.2kVA SRT models

Right-Sizing Runtime — Talk to a Questyme Specialist
The right number of external battery packs depends on actual connected load, runtime target, and generator coordination plans. Adding too many packs is expensive overhead; too few defeats the purpose. Questyme builds a runtime model for your specific environment before recommending pack count. Contact Questyme for a runtime assessment.
