Direct Replacement for APC SMT750I UPS

This two-pack of 12 V lead-acid cartridges is built to match the original RBC48 specification for the APC Smart-UPS SMT750I. Each unit is guaranteed 100 % compatible so the UPS recognises the batteries immediately and resumes backup operation without configuration. The pack suits administrators who need a like-for-like swap to keep critical loads protected.

Sealed Valve-Regulated Construction

The maintenance-free cells arrive pre-charged and ready to install in the existing battery tray; no acid handling or venting is required. Standard F2 faston terminals align with the UPS wiring harness for a secure, tool-free connection. The sealed design prevents leakage in any orientation, making the cartridges suitable for rack or tower deployments where space is tight.
