What to Check Before Buying a Used Eaton 5PX/9PX UPS System in 2026

Battery health: Measure individual cell voltage with a multimeter. Reject if any cell is below 2.3V (nominal 2.4V for 12V batteries).
Capacitor ESR: Use an LCR meter to test bulk capacitors. ESR above 30mΩ indicates failure risk.
Inverter output stability: Load-test with a power analyzer. THD must stay <3% at 50% load.
Firmware version: Systems with revision <5.1 lack IEC 62040-3 compliance for modern grid fluctuations.
