Questions about this item

What are the exact dimensions of the APCRBC155-PW cartridge so I can confirm it fits my SRT1000XLA UPS?

The cartridge measures 17.75 inches long, 7.25 inches wide and 3.00 inches high, matching the original Battery Cartridge #155 form factor for the listed SRT models.

How do I install the replacement cartridge in my SRT1500RMXLI and what step is commonly missed?

Power down the UPS, remove the front bezel, slide out the old cartridge, insert the new APCRBC155-PW until it seats firmly, replace the bezel, then run the UPS self-test to reset the battery timer.

When will the sealed lead-acid cells in this 25.45 lb cartridge need replacement again?

Expect a typical service life of three to five years; the UPS will signal replacement when runtime drops or the battery alarm sounds, at which point you swap in a fresh cartridge.
