About this replacement
Clevo W970KLQ — 14.8V Li-ion Replacement Battery (W950BAT-4)
This is a 14.8V, 2200mAh (32.56Wh) Li-ion replacement battery for the Clevo W970KLQ and W950KU series notebooks. It also fits the W970SUW, W970 LUQ, and sixteen additional Clevo models sharing the same OEM part number W950BAT-4. Install it when the original cell no longer sustains voltage under load.
- W950/W970 platform fit: These models share the same 14.8V four-cell battery bay, connector pinout, and BMS communication protocol — the W950BAT-4 part number covers the full platform without hardware modification.
- Bench tested on actual hardware: We ran this cell through charge, discharge, and BMS handshake verification. The protection circuit tripped correctly at low-voltage cutoff and the BIOS recognised the battery as a known cell on reconnect.
- Post-install calibration cycle: After fitting, run the laptop down to hibernate cutoff under normal workload, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the false health warning that appears after every cell swap on Clevo firmware.
Why the W970KLQ shuts down at 20–30% after a battery swap
The fuel gauge IC on the Clevo motherboard stores learned discharge curves from the previous cell. A new cell has different internal resistance and voltage characteristics at low charge. The BIOS maps the old curve onto the new cell and calls shutdown far too early. One full calibration cycle — discharge to hibernate, then a clean full charge — rewrites that curve and corrects the cutoff point.
BIOS shows battery health as "poor" or capacity as 0% after fitting new cell
This is an EEPROM data mismatch, not a faulty battery. The firmware holds cycle count and health metrics from the old cell in non-volatile memory. Until the BIOS completes a learn cycle against the new cell, it reports stale data. Run one full discharge-to-hibernate followed by an uninterrupted charge to 100%. After that cycle, the health indicator should reset to normal.
