Questions about this item

How do I install the PowerWarehouse 12 V lead acid cartridge in my APC Back UPS Pro BP420C?

Power down the UPS, open the battery door, disconnect the old cartridge, insert the new 2XRBC2SLA219 cartridge matching the polarity, close the door and power the unit back on.

What replacement schedule should I plan for the two cartridges in this pack?

Replace both 12 V cartridges together when the UPS runtime falls noticeably below the original backup time; a typical cycle is three to five years under normal load.
