Replacement Battery for SU and DL UPS

The BTI SLA12-BTI is a new sealed lead-acid battery designed to restore runtime in compatible APC Smart-UPS units. It replaces OEM part RBC12 and fits models including the SU2200RM3U, SU3000RM3U, SU5000RMT5U, DL2200RM3U and DL3000RM3U series.

Direct OEM RBC12 Equivalent

This battery carries the RBC12 OEM number, confirming electrical and mechanical parity with the original cartridge. Installing it returns the UPS to factory-rated backup time without firmware changes or configuration steps.

Hot-Swap Cartridge Installation

The pack slides into the front-access battery bay of the listed rack-mount and tower UPS models while the unit remains online. No tools are required, but the UPS must recognise the new cartridge before the replacement-battery indicator clears. It does not suit UPS units outside the SU, DL or NS families listed above.

Questions about this item

How often will the SLA12-BTI battery need replacing under normal UPS duty?

Typical sealed-lead-acid UPS batteries last three to five years; plan a replacement cycle in that range for the SLA12-BTI.

What runtime limit appears first when the SU5000RMT5U runs continuously on this battery?

The battery's amp-hour capacity sets the runtime ceiling; once the stored charge is depleted the UPS will shut down.

How much heat does the SLA12-BTI generate during an all-day power outage?

Sealed-lead-acid chemistry releases modest heat during discharge; normal cabinet ventilation handles it without extra cooling.
