Teledyne PMAT 2000 11.1V Replacement Battery 6700mAh

Teledyne PMAT 2000 — 11.1V Li-ion Replacement Battery

This 11.1V, 6700mAh lithium-ion pack replaces the internal battery in the Teledyne PMAT 2000 multi-parameter water quality analyzer. It restores full operating capacity to instruments used in environmental field surveys and water quality assessments. Capacity figures are taken from product data — 74.37Wh total energy.

• PMAT 2000 platform fit: The PMAT 2000 uses a three-cell 11.1V Li-ion configuration to power its sensor array, display, and logging module from a single pack. Voltage rail and connector geometry match the OEM bay — no modification needed.
• Bench tested on actual hardware: We cycled this pack under sustained multi-sensor load and monitored the BMS across probe initialisation events. The protection circuit handled the current spike at sensor power-up without tripping into lockout, and cell balance held across repeated discharge cycles.
• Pre-deployment calibration cycle: After fitting this pack, run a full calibration sequence through the PMAT 2000 instrument menu before heading into the field. The instrument maps battery state during calibration — skipping this step causes premature low-battery warnings during the first active measurement session.

Probe module current spike tripping BMS on the PMAT 2000

When the PMAT 2000 powers its probe module, the sensor array draws a sharp initialisation current before settling to steady-state load. Some third-party packs have a BMS threshold set low enough that this spike triggers an overcurrent cutoff — the instrument appears to boot, then immediately dies. This pack's BMS is calibrated to tolerate the probe start surge without nuisance tripping. If you do see a cutoff at probe power-up, confirm the battery is above 10.5V resting before powering on.

PMAT 2000 readings resetting mid-logging session

Sustained simultaneous sensor load — dissolved oxygen, conductivity, and pH probes running together — pulls consistent current across a long session. If the cell voltage sags below the instrument's brownout threshold under that combined draw, the PMAT 2000 can reset its active logging session without fully powering off. This is not a firmware fault — it is a voltage dropout event at the instrument's supply rail. A pack with degraded cells will sag earlier and more severely. If resets occur on a charged pack, check resting voltage: a healthy fully-charged cell group should read at or above 12.4V before deployment.
