Replacement Battery for APC BR1200

This 12V 7.0AH AGM pack replaces the APC RBC33 cartridge number 33 in the BR1200 UPS and compatible Back-UPS models listed by the supplier. It is built for owners who need a direct 100 percent OEM replacement that fits the existing battery compartment without modification. The leakproof design uses advanced AGM technology and requires no maintenance during its service life. Buyers who need a different voltage, capacity or form factor should look elsewhere.

Compatibility Limits

The cartridge fits units that contain exactly two internal batteries; systems with a single battery require a different RBC2 unit instead. Verify the battery count by opening the battery door before ordering because the same UPS family uses different cartridge configurations. The pack also replaces a long list of BK, BP, BE, SU, SC and SP model numbers supplied by the manufacturer. Installers who cannot confirm the internal battery quantity cannot use this cartridge.

Decisive Specification

The 7.0AH capacity at 12 volts determines whether this pack matches the runtime and load requirements of your specific UPS. If your application demands a higher ampere-hour rating or a different voltage, this cartridge will not meet the need. The expected service life ranges from four to seven years under normal operating conditions. Choose this pack only when the 7.0AH rating aligns with the original specification.

Questions about this item

Which APC UPS models does the RBC33 cartridge #33 replace?

The pack fits APC models including BR1200, BK250B, BK280B, BP280, BP350, BK300, BK350, BK400, BK500, BP420, BP500, BE500R, BE500U, BE500V, SU420VS, SU420NET, SC420 and the F6C550-AVR Rev A unit.

What runtime can I expect from a 12 V 7.0 Ah AGM pack in my BR1200 UPS?

Runtime depends on the connected load; at a typical 100 W draw the 7.0 Ah pack will supply roughly 40–50 minutes, while lighter loads extend it proportionally.

Does the RBC33 cartridge use a standard connector that plugs straight into the BR1200?

Yes, the cartridge is a 100 % OEM replacement with the same terminal layout as the original APC battery, so it connects directly without adapters.
