Questions about this item

Does the APC SC420 UPS need any extra cables to install these 12 V 273 cartridges?

The 2-pack is a direct cartridge swap for the SC420; no additional cables or adapters are required.

Will the 12 V lead-acid cells in this 2-pack run hotter than the original batteries in an older SC420 unit?

They match the original 12 V specification, so thermal behaviour inside the SC420 stays the same.
