Questions about this item

How much heat does the 12 V lead-acid cartridge generate when the UPS runs continuously?

The sealed 12 V lead-acid cells produce only modest warmth under normal float charge; the host UPS handles any heat through its own ventilation.

What must I already own for these two cartridges to work?

You need an APC SU1400RMBX120 UPS that accepts cartridge #8; the pack contains two direct replacements for that model.
