APC BK300X116 compatible battery pack

This 2-pack of 12V lead-acid cartridges is built to fit the APC BK300X116 uninterruptible power supply. It restores backup runtime for home-office networking gear, entry-level servers or point-of-sale terminals. The pair arrives new and ready to install without tools.

Drop-in replacement frees the original chassis

Each cartridge slides into the existing battery bay so the UPS enclosure stays sealed and no extra cabling is required. The 100% compatibility guarantee means the unit will self-test and charge normally after the swap. Buyers needing extended runtime beyond the standard BK300 capacity or a different form-factor battery should look elsewhere.

Questions about this item

What is the voltage limit of the 12V lead-acid cells under sustained UPS load?

Each cartridge delivers 12 volts nominal; the UPS electronics manage the discharge curve and low-voltage cutoff, so the cells themselves do not expose a separate sustained-use limit.

Do the sealed 12V lead-acid cartridges produce audible noise or measurable heat during continuous all-day operation?

Sealed lead-acid chemistry has no moving parts; the batteries remain silent and only warm slightly under normal float or discharge cycles inside the APC BK300X116.
