Compatible UPS Models

This 12V 2-cell lead-acid replacement battery fits several APC Smart-UPS rack-mount units including the SU700R2BX120, SU700R2IBX120, SU700RM2U and SU700RMI2U. It also supports the SUA750R2IX38, SUA750R2X122 and SUA750R2X338 models.

Questions about this item

How often does the 12V 2-cell lead-acid battery need replacement under normal UPS operation?

Plan to replace the RBC22-SLA22-TAA every three to five years; runtime loss and swelling are the first signs it is nearing end of life.

What limits runtime first during a prolonged outage on a Smart-UPS RM SU700RMI2U?

The 12V 2-cell capacity is the limiting factor; once the cells reach deep-discharge voltage the UPS shuts down to protect the battery.

Does the RBC22-SLA22-TAA generate noticeable heat or fan noise when the UPS runs all day on mains?

The sealed lead-acid cells produce minimal heat during float charging, so the UPS fan typically stays at low speed or remains off.
