Thermo Scientific Novus 175-8060 Li-ion Compatible Battery 3.7V 950mAh

Thermo Scientific Novus & Finnpipette Novus — 3.7V Li-ion Replacement Battery (175-8060)

This 3.7V Li-ion cell at 950mAh (3.52Wh) replaces the original battery in the Thermo Scientific Novus portable analyzer and Finnpipette Novus series, including single-channel and multichannel electronic pipette variants. It matches OEM part numbers 175-8060, 175-8061B, 12905550, and 12905590. Physical dimensions are 48.60 × 32.77 × 6.60mm — check your existing cell before fitting.

• Novus analyzer and Finnpipette compatibility: Both the handheld clinical analyzer and the Novus electronic pipette line share this cell format and voltage rail. The BMS in each device uses the same 3.7V nominal reference and connector footprint, so one cell covers the full Novus platform.
• Bench tested on actual hardware: We cycled this cell through the Novus BMS handshake and confirmed charge acceptance, protection circuit engagement at low-voltage cutoff, and stable discharge across the full capacity band. The BMS flagged no chemistry mismatch during initialisation.
• Post-swap self-test protocol: After installing this cell, let the device complete its full power-on self-test without interrupting the boot sequence. The Novus BMS runs a battery verification pass at startup — cutting power during that window logs a false battery fault that persists until the next clean reboot.

Why the Novus alarms low battery immediately after a confirmed full charge

The Novus BMS stores a learned capacity profile from the OEM cell. A new replacement cell has no cycle history in that profile, so the BMS compares the fresh cell's impedance against its stored baseline and flags a mismatch as a low-battery condition. This is not a fault with the cell — it is the BMS self-test threshold working exactly as intended. Run one complete charge-to-discharge cycle to let the BMS build a new baseline. After that first cycle, the low-battery alarm clears and the charge indicator reports accurately.

Novus will not power on after the replacement cell sat in storage

Li-ion cells self-discharge during storage at roughly 2–3% per month. If a replacement cell has been stored for several months, its resting voltage can drop below the Novus BMS recovery threshold — typically 2.5V — and the device will not boot at all. The BMS interprets anything below that floor as a damaged or absent cell and blocks power delivery as a protection measure. Connect the device to its charger for at least 30 minutes before attempting to power on; most chargers apply a low-current pre-charge trickle at voltages below 3.0V that brings the cell back into the recoverable range.
