Questions about this item

How often should I replace the 12 V lead-acid cartridges in the SP500DR UPS?

Replace both cartridges every three to five years or when runtime falls noticeably below the original level.

What component limits runtime first during an extended outage on the SP500DR?

The 12 V lead-acid cells deplete first; once their voltage drops the UPS shuts down.
