SKU CH-J9DH-BRBTQ

12 V, four-cell lead-acid replacement battery for compatible APC Smart-UPS X 1500 RM models

  • TypeBattery
  • Designed for APC Smart-UPS X 1500 RM models
  • Direct replacement for APCRBC115 and RBC115 part numbers
  • 12 V 4-cell lead-acid chemistry for reliable backup
  • TAA-compliant for government and regulated purchases
  • Ready-to-install cartridge restores UPS runtime quickly

Compatible UPS Models

This 12 V lead-acid replacement battery fits select APC Smart-UPS X units including the SMX1500RM2U, SMX1500RM2UNC, SMX1500RMI2U, SMX1500RMI2UNC, SMX1500RMNCUS and SMX1500RMUS. It replaces the APCRBC115 and RBC115 cartridges. The four-cell pack restores runtime for rack-mounted UPS systems in server rooms and network closets. Buyers who need a different form factor or voltage should verify their UPS model first.

Installation Notes

The battery cartridge slides into the front-access compartment of the listed Smart-UPS X models without tools. Polarity is keyed so the connector mates one way. A common issue is forgetting to remove the protective terminal covers before insertion, which prevents the UPS from recognising the new pack. Another is seating the cartridge incompletely, leaving the latch unlatched and causing an alarm.

Pre-Order Checks

Confirm the exact UPS model number on the rear label matches one of the six SMX1500 variants above. Verify the existing battery carries the APCRBC115 or RBC115 part number. Ensure the UPS firmware is current so the self-test recognises the replacement pack. This battery is not suitable for UPS units that require a different cartridge size, cell count or chemistry.

Questions about this item

How can I confirm the APCRBC115-TAA is working correctly after installing it in my SMX1500RM2U?

After installation, power on the UPS and let it charge for the recommended period. Then run a self-test from the front panel or management software; a passed test and normal runtime during a simulated outage show the 12V 4-cell pack is operating as intended.

What comes with the APCRBC115-TAA and what must I source separately?

The package contains the 12V 4-cell lead-acid battery cartridge that replaces APCRBC115 and RBC115. No cables, mounting hardware or management software are included; reuse the existing connectors and rails from your SMART-UPS X unit.

Which version should I choose for a SMART-UPS X SMX1500RMI2UNC?

The APCRBC115-TAA is the direct replacement for every listed SMART-UPS X model, including the SMX1500RMI2UNC. No alternative capacity or version exists for these units; select this SKU for all 1500 VA rack-mount models shown.
