Questions about this item

How long will the sealed lead-acid cells last before capacity drops under daily cycling?

The cartridge uses six 12 V 5.5 Ah sealed lead-acid batteries rated for 0–40 °C operation; typical service life is three to five years depending on depth of discharge and ambient temperature.

Does the battery pack generate noticeable heat or fan noise during continuous float charging?

Sealed lead-acid chemistry produces minimal heat while on float charge and the cartridge has no moving parts, so it adds no audible noise to the UPS.

Which UPS models accept this 3.0 × 8.25 × 15.75 inch, 24.5 lb cartridge without modification?

The APCRBC141-CP is a direct user-replaceable fit for CyberPower UPS units designed for the RBC141 form factor; verify your UPS manual lists RBC141 as the compatible replacement cartridge.
