Your server's been running on battery for twenty minutes and the runtime counter is ticking down fast. This 72V pack slots into your APC Smart-UPS SRT 2.2kVA rackmount unit and buys you the extra hours you actually need before the next shift starts. Lead-acid chemistry, 2U footprint, drops straight into SRTRK3 or SRTRK4 enclosures without re-wiring. Cell-level monitoring tells you exactly when to swap it out – before it's too late. Ships with rack brackets, an install guide, and full documentation. If your current pack is at APCRBC141 spec, this is the direct replacement. Add to cart and we'll get it moving to your site
