Two-battery UPS replacement kit

This pack contains two 12V 18Ah sealed lead-acid batteries built with AGM technology. They are designed as a direct replacement for APC SU3000RMNET, AP1250 and AP1400 units. The maintenance-free design requires no water checks during its service life.

12V 18Ah AGM specification

The 12V 18Ah rating determines whether this kit matches your UPS model. Each battery uses absorptive glass mat construction to prevent electrolyte leakage. Gas recombination exceeds 90% during normal operation. Position-free sealing allows installation in any orientation without spill risk.

Sealed maintenance-free operation

AGM construction keeps the electrolyte absorbed in glass-fibre separators for steady service. Over 90% of generated gas recombines internally during normal use. No water top-ups or specific-gravity checks are needed throughout the expected 4-7 year floating life. Non-spillable classification meets air-transport requirements.

Questions about this item

How long will the 18Ah capacity actually keep my SU3000RMNET running?

Runtime depends on the load connected to the UPS; the 18Ah rating gives the total energy stored, so lighter loads run longer and heavier loads run shorter.

What connection standard do these batteries use inside the APC unit?

They use the standard faston terminal layout that the SU3000RMNET, AP1250 and AP1400 expect, so no adapter or rewiring is needed.

Will the two batteries fit the existing tray and mounting points?

Yes, each 12V 18Ah block matches the OEM dimensions for the SU3000RMNET, AP1250 and AP1400, so they slide into the original tray and secure with the existing hardware.
