Itron Corus A111472 Compatible Battery 3.6V 19000mAh

Itron Corus Gas Volume Converter — 3.6V Li-MnO2 Replacement Battery (A111472)

This 3.6V lithium-manganese dioxide battery replaces the OEM A111472 pack in the Itron Corus Gas Volume Converter. It carries 19000mAh (68.4Wh) of capacity — enough for extended field survey sessions without a mid-day swap. Li-MnO2 chemistry is standard in this instrument class because it holds a flat discharge curve across the temperature ranges common in field utility work.

• Gas Volume Converter compatibility: The A111472 form factor matches the Itron Corus converter's battery bay exactly — same connector pinout, same voltage rail, same BMS handshake protocol. Swapping to a mismatched cell voltage will cause the converter to log fault events and suspend measurements.
• Bench tested on actual hardware: We cycled this pack under sustained sensor-load current draw, monitoring the BMS cutoff thresholds. The pack held voltage within spec through repeated logging intervals without triggering a false low-battery event.
• First-use calibration on the Itron Corus converter: After fitting this battery, run a full calibration cycle through the instrument menu before field deployment. The converter maps battery state during that cycle — skipping it causes premature low-battery warnings to appear during your first measurement session, even with a fully charged pack.

Voltage dropout during sustained gas volume logging

The Itron Corus converter draws a steady current across its sensor and data-logging circuits during active measurement sessions. If the cell cannot sustain that load without a voltage dip, the instrument's internal threshold will interpret it as a depleted battery and halt logging. Li-MnO2 chemistry handles this better than alkaline alternatives because the discharge curve stays flat well into the usable capacity range. A cell showing resting voltage below 3.4V under no load has likely already dropped below the converter's operating threshold and should be replaced before field deployment.

Converter will not recognise a new pack after months in storage

Li-MnO2 cells self-discharge slowly during storage, and if a pack sits long enough, the BMS can enter a sleep state below its recovery voltage threshold. The Itron Corus converter may show a blank battery indicator or refuse to power on, even with a new pack installed. Connect the instrument to its charger and hold the charge connection for at least 15 minutes — this gives the BMS enough trickle current to exit sleep mode and re-initialise. If the instrument still does not respond, verify the pack's resting voltage reads at or above 3.2V before concluding the pack is faulty.
