About this replacement
Nova StatStrip Glucose Meter / TPS-2003 — 3.7V Li-Polymer Replacement Battery (654141)
This 3.7V, 1800mAh lithium-polymer battery is a direct replacement for the Nova StatStrip Glucose Meter and TPS-2003. It restores power to the test strip reader and digital display after the original cell has degraded. OEM part number 654141 confirms fitment across both listed models.
- StatStrip and TPS-2003 compatibility: Both models share the same 3.7V power rail, 654141 connector footprint, and BMS handshake protocol. Swapping between these two device variants requires no hardware modification — the BMS on each unit accepts the same charge profile and cell chemistry.
- Bench tested on actual hardware: We cycled this cell through the StatStrip's full charge-discharge sequence and confirmed the BMS accepted the Li-Polymer charge curve without fault. The protection circuit engaged correctly at both the low-voltage cutoff and charge termination thresholds.
- Post-installation startup sequence: After fitting this battery, allow the StatStrip to complete its full power-on self-test without interruption. The device runs a BMS verification routine at boot — cutting power mid-sequence triggers a persistent battery fault that clears only on a full reboot, not a simple restart.
Why the StatStrip shows a low battery alert immediately after a confirmed full charge
The StatStrip's BMS stores charge-cycle history from the previous cell. When a new cell is installed, the BMS compares its internal state-of-charge model against the new cell's resting voltage, and a mismatch can trigger a false low-battery flag. This is not a fault with the replacement cell — it is a calibration gap. Run one complete charge-discharge cycle from full to the device's automatic cutoff, then charge to 100% again. After that cycle, the BMS recalibrates its capacity model to the new cell and the alert clears.
StatStrip will not power on after the replacement cell sat in storage
Li-Polymer cells self-discharge during storage. If the cell voltage dropped below approximately 3.0V before installation, the StatStrip's BMS may block startup entirely as a protection measure. Connect the device to its charger for a minimum of 30 minutes before pressing the power button — the charge IC applies a low-current pre-charge to bring the cell above the BMS recovery threshold before normal charging begins. Once the device shows a charging indicator, allow it to reach a full charge before use.
