Questions about this item

How long will the 28 Ah capacity keep my SU3000RMNET running during a power cut?

Runtime depends on the load connected to the UPS; the 28 Ah rating shows the total charge available, so lighter loads run longer while heavier loads draw it down faster.

Does the RBC11 cartridge use a standard terminal type that fits the SU3000RMNET without adapters?

Yes, the cartridge is built as a direct replacement for the APC RBC11, so its terminals match the SU3000RMNET battery compartment exactly.
