Questions about this item

Does the 12 V lead-acid cartridge generate noticeable heat or noise during continuous UPS operation?

The sealed lead-acid design runs silently and produces only minimal warmth under normal load.

Must the APC BE359R UPS already be installed for these two cartridges to work?

Yes, they are direct replacements for the BE359R unit, so that UPS must be in place first.
