TAA-Compliant 12 V Lead-Acid UPS Battery

This replacement battery uses four sealed lead-acid cells to deliver 12 volts of backup power. It is built for IT managers who need a TAA-compliant spare that fits directly into supported APC Smart-UPS rack-mount units. The pack arrives new and ready for installation without additional configuration.

Steady Output During Extended Runtime

The lead-acid chemistry maintains a consistent voltage curve throughout the discharge cycle rather than dropping sharply after a short burst. This behaviour keeps connected equipment running predictably during prolonged outages. The sealed design also limits gas release, so the battery operates safely inside enclosed rack cabinets.

Direct Fit for Listed APC Smart-UPS Models

Compatibility is limited to the specific APC model numbers supplied by the manufacturer, including the SU1400 and SUA1500 rack-mount families. Units not appearing on that list will not accept this pack mechanically or electrically. Verify the exact model label on the UPS before ordering.

Questions about this item

How much heat does the 12V 4-cell lead acid battery generate during continuous UPS operation?

The sealed lead acid chemistry produces minimal heat under normal float charge; the UPS enclosure handles thermal management.

Which APC Smart-UPS models must I already own for this RBC24-SLA24-TAA to be compatible?

It fits SU1400R2BX120, SU1400RM2U, SUA1500RM2U and the other listed 1400 and 1500 series rack-mount units.

Will this replacement battery work alongside the original RBC24 cartridges already installed in my SUA1500RM2U?

Yes, it directly replaces the RBC24 cartridge and is TAA-compliant for use in the same APC Smart-UPS RM chassis.
