Questions about this item

When will the RBC18-compatible battery cartridge need replacement?

Plan on replacing the cartridge after three to five years of normal service; the two 6 V 9 Ah cells inside degrade with each discharge cycle.

What limits runtime during a prolonged outage?

The 450 VA rating and the paired 6 V 9 Ah batteries set the energy reserve, so extended loads will exhaust capacity quickly.
