Direct-fit UPS battery replacement

This two-pack supplies 12 V lead-acid cartridges built to match APC cartridge #6 specifications. Each unit is guaranteed 100 % compatible with the original equipment so the UPS recognises the battery immediately. The pack suits administrators who need a ready-to-install swap for ageing cells in rack or tower units. No extra wiring or firmware steps are required.

Sealed lead-acid thermals and draw

The sealed construction prevents electrolyte leakage and keeps gas recombination internal during normal float charging. Self-discharge stays low so stored spares hold voltage for months without a top-up charge. Under typical load the cells run at ambient temperature with no audible fan noise from the battery itself. Power draw is limited to the UPS charger current, adding negligible heat to the rack environment.

Questions about this item

How do I install the 12 V cartridge #6 batteries in my APC UPS, and which step do people often miss?

Power down the UPS, open the battery compartment, disconnect the old cartridge, connect the new 12 V cartridge #6 units observing the red-to-red and black-to-black polarity, secure the compartment door, then turn the UPS back on and let it charge for the recommended period before relying on backup power.

What maintenance or replacement will the 12 V lead-acid cartridge #6 pack need later?

The sealed lead-acid cells in cartridge #6 typically last three to five years; plan to replace the pair when runtime drops noticeably or the UPS signals a battery fault, and keep the units at room temperature with a full charge during storage to maximise service life.
