APC Smart-UPS 1400 Battery Kit

This replacement kit is designed for the APC Smart-UPS 1400 SU1400INET uninterruptible power supply. It contains two 12V 18A batteries pre-fused with a harness installed for direct cartridge exchange. The kit is factory fresh and ready for immediate installation in compatible UPS units.

Sustained Load Performance

Under continuous discharge the matched 12V 18A cells deliver stable voltage until the UPS initiates its controlled shutdown sequence. The fused harness limits fault current during extended runtime events, protecting both the battery string and the UPS electronics. Internal resistance remains consistent across the pair, preventing cell imbalance that would shorten service life during repeated deep cycles.

Questions about this item

How much heat does the SU1400INET battery kit generate when running continuously?

The two 12V18A batteries produce heat typical for sealed lead-acid cells under load; ensure the UPS ventilation slots stay clear and ambient temperature remains within the unit's rated range.

What existing UPS hardware is required for this replacement kit to work?

It fits APC Smart-UPS 1400 models using the RBC7 cartridge; the harness is pre-fused and installed so you only need the UPS chassis and its original battery compartment.
