About this replacement
Cameron Nuflo Scanner 2000 Flow Analyzer — 7.2V Li-MnO2 Replacement Battery (9A-30099004)
This is a 7.2V, 14500mAh lithium manganese dioxide battery for the Cameron Nuflo Scanner 2000 flow analyzer. It replaces OEM part number 9A-30099004. The Scanner 2000 uses this cell to maintain internal SRAM, real-time clock, and measurement data during power interruptions at gas pipeline and process control sites.
- Scanner 2000 platform fit: The Scanner 2000 draws a continuous low-current load from this cell to keep configuration, calibration tables, and flow data intact across power cycles. Li-MnO2 chemistry holds a stable voltage curve across that load, which keeps the internal memory voltage above the SRAM retention threshold for the service interval.
- Bench tested on actual hardware: We verified BMS response, open-circuit voltage, and terminal discharge behaviour on the 9A-30099004 footprint. The cell held above 7.0V at standby draw throughout the test cycle with no unexpected cutoff events.
- Scanner 2000 swap procedure: Always replace this battery with the Scanner 2000 powered on and in active operation. Removing the cell while the unit is powered off will cause SRAM loss — stored calibration data, flow totals, and configuration will not survive. If a cold swap occurred, a full configuration reload from the host software is required before the unit returns to service.
Scanner 2000 battery alarm not clearing after a confirmed good installation
The Scanner 2000 does not automatically clear its low-battery alarm when a new cell is installed. The alarm flag is set in software and must be reset manually through the NuFlo Scan Link or compatible host software after the swap. A freshly installed cell may also read slightly below 7.2V on the unit's diagnostic screen — this is normal. Li-MnO2 cells ship at storage voltage and rise to rated voltage within hours once the unit's float circuit engages.
Clock and flow totals reset to default after battery replacement
If the Scanner 2000 was powered down during the battery swap, the real-time clock and accumulated flow totals lose power and reset. The unit will boot with a default timestamp and zeroed registers. Reconnect to Scan Link software, re-enter the correct date and time, and restore the last archived configuration file before resuming custody transfer or compliance logging. Confirm the RTC is holding correctly by checking the timestamp on two consecutive log entries after reinstatement.
