Questions about this item

When should I replace the two RBC18 cartridges?

Plan to swap both cartridges after 3 to 5 years of service, or sooner if the UPS reports a battery fault.

What runtime limit appears first during a long outage?

The 6 V lead-acid cells will hit their voltage floor and shut down the BAY450 once the stored charge is exhausted.
