Compatible Replacement for APC Smart UPS SU24XLBP

This two-pack of 12V lead-acid battery cartridges is built to fit the APC Smart UPS SU24XLBP. Each unit is guaranteed 100% compatible with the original equipment. The product is supplied new and carries a one-year replacement warranty on all batteries. It is designed for users who need a direct drop-in power source for that specific UPS model.

Thermals Noise and Power Draw

Lead-acid chemistry runs without active cooling so the cartridges produce no fan noise during normal operation. Heat output is low under typical float-charge conditions and the sealed construction prevents electrolyte leakage. Power delivery matches the original 12V specification for the supported UPS. Buyers who need a different voltage or form factor should look elsewhere.

Questions about this item

How do I install the two 12 V cartridges into my APC Smart UPS SU24XLBP, and what step is often missed?

Power down the UPS, open the battery compartment, disconnect the old cartridges noting the red-to-red and black-to-black leads, insert the new pair in the same orientation, then secure the cover before turning the UPS back on.

When will these lead-acid cartridges need replacement, and what indicates it?

Expect three to five years of service; the UPS will signal replacement when runtime drops sharply or a battery-fault alarm sounds during self-test.
