Questions about this item

How often should the two 6V9Ah batteries inside the RBC18-compatible cartridge be replaced?

Plan to swap the cartridge every three to five years; the sealed lead-acid cells lose capacity gradually and a fresh kit restores the original runtime.

What is the first limit reached when the Smart-UPS C 450 runs continuously at full load?

The 450 VA output rating is the ceiling; once the connected equipment draws that much apparent power the UPS cannot supply more and will switch to battery until the 18 Ah reserve is exhausted.
