About this replacement
Lenovo V330-14IKB / V130-14IKB Series — 7.7V Li-Polymer Replacement Battery (L17M2PB1 / 5B10P53997)
This is a 7.7V, 3900mAh (30.03Wh) Li-Polymer replacement battery for the Lenovo V330-14IKB and V130-14IKB notebook series. It matches the OEM voltage rail, connector, and BMS communication protocol of the original cell. Direct fit for models including V130-14IKB-81HQ00ENGE, V130-14IKB-81HQ00MNGE, and V130-14IGM-81HM009NGE.
- V330 and V130-14 series fit: These models share the same 7.7V two-cell Li-Polymer architecture, identical 5-pin connector pinout, and the same BMS handshake protocol — which is why one cell part number (L17M2PB1) covers the entire platform.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a V130-14IKB unit. The BMS accepted the cell without fault codes, charge termination triggered correctly at 8.70V, and the fuel gauge IC communicated state-of-charge data to Windows without error.
- Post-install calibration on Lenovo IdeaPad: After fitting this battery, run a full discharge down to automatic hibernate cutoff, then charge uninterrupted to 100% without unplugging mid-cycle. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on IdeaPad firmware.
Why the V330-14IKB shuts down at 20–30% remaining after a battery swap
The V330's EC firmware maps shutdown thresholds against a learned voltage-versus-capacity curve from the previous cell. A new Li-Polymer cell has a slightly different discharge curve, so the firmware triggers a low-battery shutdown before the actual state of charge hits zero. The fix is a full battery learn cycle: discharge to hibernate cutoff, then charge to 100% without interruption. After two to three of these cycles, the fuel gauge IC recalibrates against the new cell's curve and the early shutdowns stop.
BIOS reporting 0% or "unknown" battery immediately after installing the replacement
This is an EEPROM mismatch — the embedded controller is reading authentication data from the old cell's memory and getting no valid response from a new cell. It does not mean the battery is faulty. Boot into the Lenovo BIOS, navigate to the Power settings, and run the Battery Reset or Gauge Reset function if available; otherwise boot into Windows and let the cell charge fully to 100% before the OS fuel gauge registers a valid reading. If the BIOS still shows 0% after one full charge cycle, reseat the battery connector to ensure pin contact at all five positions.
