Questions about this item

How long will the 12 V 9 A battery keep a 350 VA UPS running under full load?

Runtime depends on the load attached to the UPS; at maximum rated draw the battery typically supplies power for several minutes, giving time to save work and shut down safely.

Does the sealed lead-acid cell generate noticeable heat or fan noise during continuous float charging?

The battery itself is silent and produces only mild warmth during float charge; any audible fan noise comes from the UPS enclosure, not the cartridge.

Will the cartridge fit my Liebert PSA350MT3-120U without extra cables or mounting brackets?

Yes, the kit is built as a direct drop-in replacement for the PSA350MT3-120U and includes the original connector and hardware.
