Questions about this item

Will this 12 V 7.2 A battery fit the APC Smart-UPS SC 1500 VA unit I already own?

Yes, the RBC59-SLA59-BTI is a direct replacement for the APC Smart-UPS SC 1500 VA, matching the original 12 V 7.2 A specification and four-cell sealed lead-acid design.

How can I confirm the battery is operating correctly once installed in the UPS?

After installation, run the UPS self-test from the front panel or management software; a passed test and normal runtime during a brief power pull show the 12 V 7.2 A pack is working as intended.
