Questions about this item

How do I install the 12 V cartridge #2 into my BP500CLR and what step is often missed?

Open the battery door, unplug the old pack, connect the new cartridge's terminals matching red to red and black to black, then close the door and let the UPS charge for eight hours before relying on backup.

When will the 223 model lead-acid cells need replacement and what signals the end of life?

Expect three to five years of service; the UPS will sound a periodic beep and show a replace-battery LED when internal resistance rises and runtime drops below useful levels.
