What this battery replaces

The RBC48-SLA48-BTI is a sealed lead-acid replacement battery built for APC UPS units rated at 750 VA. It matches the original manufacturer specifications for models including SUA750, SUA750US, SUA750I, SMT750, SMT750I, SMT750TW, SMT750US, DLA750 and DLA750I.

Questions about this item

Will the RBC48-SLA48-BTI battery fit inside my APC SUA750 UPS without modification?

The battery is built as a direct replacement for APC models including SUA750, SUA750I and SUA750US, so it matches the original form factor and requires no changes to the chassis.

What is the correct order for connecting the leads when I install this replacement battery?

Disconnect the UPS from mains power, remove the old pack, then attach the red lead to the positive terminal and the black lead to the negative terminal before securing the cover.

How often should I expect to replace this sealed lead-acid battery in normal use?

Sealed lead-acid UPS batteries typically last three to five years; plan to swap the pack again within that window to keep runtime at spec.
