Questions about this item

How do I install the two 12 V cartridges into my Dell Smart UPS DLA1500J and what step is often missed?

Power down the UPS, open the front battery door, disconnect the old cartridge, insert the new PowerWarehouse 2XRBC6SLA637 pair in the same orientation, reconnect the wiring harness, close the door, then run the UPS self-test so the firmware recognises the fresh cells.

What ongoing maintenance does this 12 V lead-acid pair need and when should I plan replacement?

Run the built-in self-test every three to six months; keep the unit in a cool, ventilated area; expect roughly three to five years of service before runtime falls off and the cartridges need swapping.
