# SNMP UPS OIDs: UPS-MIB Battery, Input & Output Reference

The SNMP OIDs for a UPS — UPS-MIB (RFC 1628) battery status, charge, runtime, input/output voltage and load, plus the APC PowerNet-MIB, with examples.

## Frequently asked questions

### What is the OID for UPS battery status?

upsBatteryStatus at 1.3.6.1.2.1.33.1.2.1 from the UPS-MIB (RFC 1628). It's an enum — batteryNormal, batteryLow, batteryDepleted, or unknown. It sits in the battery group at 1.3.6.1.2.1.33.1.2 alongside charge percentage, runtime, voltage, and temperature.

### What OID is UPS runtime remaining?

upsEstimatedMinutesRemaining at 1.3.6.1.2.1.33.1.2.3 — the estimated minutes of runtime left on battery. Pair it with upsEstimatedChargeRemaining (.4, percentage) and alert when the minutes drop below the time your systems need for a clean shutdown.

### Standard UPS-MIB or APC PowerNet — which should I use?

Use the standard UPS-MIB (1.3.6.1.2.1.33) for portability; it works across UPS vendors and covers battery, input, and output essentials. Use the APC PowerNet-MIB (1.3.6.1.4.1.318) on APC gear when you need richer diagnostics, self-tests, or outlet-group control the standard MIB doesn't expose.

### How do I detect that a UPS is on battery?

Read upsOutputSource (1.3.6.1.2.1.33.1.4.1) — a value indicating battery means it's running off the battery rather than mains. You can corroborate with upsSecondsOnBattery (1.3.6.1.2.1.33.1.2.2), which is 0 on mains and counts up once the UPS transfers to battery.
