Questions about this item

What runtime does the 12 V 43 Ah rating give in an APC SMT3000RMI2U?

The 12 V 43 Ah capacity matches the original cartridge #43 specification, so the UPS will deliver the same backup time it was designed for when both batteries are installed.

Does the cartridge use the standard APC battery connector for the SMT3000RMI2U?

Yes, the replacement cartridge is built to the same connector and form factor as the original RBC43, allowing a direct swap without adapters.
