Lenovo IdeaPad 710S L15L4PC0 Replacement Battery 7.6V 6050mAh

Lenovo IdeaPad 710S Series — 7.6V Li-Polymer Replacement Battery (L15L4PC0)

This is a 7.6V, 6050mAh (45.98Wh) lithium-polymer replacement battery for the Lenovo IdeaPad 710S ultra-thin notebook. It fits the 710S-13ISK and related 13-inch variants, including the i5-7200U configurations. OEM part numbers L15L4PC0, L15S4PC0, and L15M4PC0 all cross to this cell.

• 710S series compatibility: All IdeaPad 710S-13 variants share the same slim 6.70mm battery bay, connector pinout, and BMS handshake protocol. The voltage rail and cell count are identical across the i5-7200U SKUs, which is why one cell covers multiple build configurations.
• Bench tested on actual hardware: We ran this cell on a 710S-13ISK unit and logged the BMS charge cycle from 0% to full. The protection circuit held charge termination at the correct voltage ceiling and passed current draw under CPU and display load without tripping the cutoff.
• First-cycle conditioning on the 710S: After installing, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.

BIOS reporting poor battery health after replacement on the 710S

The 710S BIOS stores battery health data tied to the original cell's EEPROM profile. When a new cell goes in, the BIOS compares the fresh cell against the stored degraded baseline and flags it as unknown or poor health. This is not a fault with the replacement cell — it is a data mismatch. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the BIOS to rewrite the learn cycle against the new cell's actual capacity.

This symptom means the fuel gauge IC has not yet calibrated against the new cell's voltage curve. The IC uses stored data from the old, degraded cell to predict cutoff, so it calls shutdown too early. The fix is two to three full discharge and charge cycles — no partial top-ups. After calibration cycles complete, the gauge tracks the new cell accurately and the early shutdowns stop. Confirm the cell voltage reads above 7.0V at the point the laptop previously shut down to verify calibration is working.
