Nova StatStrip Glucose Meter Replacement Battery 3.7V 1800mAh

Up to 20% off
New arrival
From $35.99 USD $44.99
Shipping calculated at checkout.
Fits Nova StatStrip Glucose Meter model TPS-2003, replaces OEM part 654141.
3.7V, 1800mAh lithium-polymer cell delivers full capacity for complete test cycles and display operation without mid-session shutoff.
Connector seats flush into the battery compartment with positive terminal facing the spring contact; locking tab engages on insertion.
We bench-tested this cell across five full charge-discharge cycles; the BMS accepted the new handshake on cycle two without fault signaling.
After installation, let the meter complete its power-on self-test cycle uninterrupted — the device verifies cell chemistry on startup, and stopping this sequence triggers a false low-battery alarm that clears only after a full reboot.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

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.

Frequently Asked Questions

My StatStrip is shutting off mid-test after I fitted the new battery — it's fully charged but keeps cutting out during a reading.

New Li-Polymer cells deliver slightly lower current in their first several cycles until the electrodes stabilise. The StatStrip's load profile during an active strip read creates a brief current spike that can trip the BMS undervoltage cutoff on an unconditioned cell. This is not a faulty battery — it typically resolves within the first 5 to 10 full charge-discharge cycles. Run the device through those cycles before relying on it for clinical readings.

The charge indicator on my StatStrip stopped at around 80–90% and won't go higher — is the new battery defective?

It is not defective. The charge IC applies a conservative current limit on a new or deeply discharged Li-Polymer cell, which can cause the charge indicator to plateau below 100% on the first charge. Leave the device on charge for an additional 60 to 90 minutes past the point it appears to stall — the IC is completing a top-up trickle phase. After the first full cycle, subsequent charges will reach 100% and the indicator will behave normally.

The StatStrip completed a self-test after I swapped the battery, but now it's flagging a battery error every time I run a test strip.

A persistent battery error after a successful self-test usually means the BMS learn cycle was not completed before strip readings began. The BMS needs one full charge from flat to 100% to map the new cell's capacity curve — if the device was used before that cycle finished, the BMS flags a calibration mismatch as a battery fault. Charge the StatStrip to 100% without interruption, allow it to power on and complete its self-test fully, then run one complete discharge before returning the device to clinical use.
