Vetronix 03002152 Replacement Battery 7.2V 2000mAh

Vetronix 03002152 / Consult II — 7.2V Ni-MH Replacement Battery (VTE03002152)

This is a 7.2V, 2000mAh Ni-MH replacement battery for the Vetronix 03002152 and Consult II handheld diagnostic and measurement instruments. It replaces OEM part numbers VTE03002152 and 02002720-01. Capacity and dimensions match the original pack: 50.75 × 53.17 × 29.43mm.

• 03002152 and Consult II compatibility: Both models share the same 7.2V cell configuration, connector pinout, and BMS handshake protocol — one pack covers both platforms without modification.
• Bench tested on actual hardware: We ran this pack through probe initialisation sequences and sustained sensor logging loads. The BMS held voltage through the current spike at probe power-up and did not trip under continuous measurement draw.
• Calibration cycle before field deployment: After installing this pack, run a full calibration cycle through the instrument menu before taking it into the field. The Vetronix firmware maps battery state during calibration — skipping this step causes premature low-battery warnings to fire during your first measurement session even when the pack is fully charged.

BMS lockout after the Consult II sat unused in a carry case for months

Ni-MH cells self-discharge over time. If the instrument sat unused long enough, the pack voltage can drop below the BMS recovery threshold — typically around 5.4V on a 7.2V Ni-MH pack. At that point the BMS enters a protection lockout and the charger sees the pack as absent or dead. A slow pre-charge at a low current rate (trickle mode, 0.1C) for 15–20 minutes is usually enough to lift the cell voltage above the recovery floor and allow normal charging to resume. Most Ni-MH chargers with a recovery or conditioning mode handle this automatically.

Readings resetting or dropping out during an active logging session

If the instrument resets or sensor readings cut out mid-session without a low-battery warning, the cause is usually voltage sag under sustained sensor load rather than a depleted pack. Ni-MH cells that have cycled heavily lose internal resistance headroom — voltage dips briefly below the instrument's operating floor when multiple sensors draw simultaneously. A replacement pack with fresh cells restores the voltage floor under load. After fitting this battery, confirm stable readings by running the instrument at full sensor load for several minutes before logging critical measurements.
