About this replacement

Lenovo IdeaPad Flex 3 11IGL05 — 11.52V Li-Polymer Replacement Battery (L19C3PF8)

This is an 11.52V, 3150mAh (36.29Wh) Li-Polymer battery for the Lenovo IdeaPad Flex 3 11IGL05 series. It fits the 11-inch 2-in-1 convertible chassis and connects using the original three-cell BMS handshake. OEM part numbers L19C3PF8, L19M3PF8, SB10X02592, SB10X02595, 5B10X02593, and 5B10X02604 all cross to this cell.

Flex 3 11IGL05 series fit: Every variant in this series — from the 82B20024IV to the 82B2001MUK and 119 additional sub-models — shares the same connector pinout, BMS communication protocol, and 11.52V three-cell rail. One cell covers the full range.
Bench tested on actual hardware: We ran this cell in an 11IGL05 chassis and confirmed the BMS authenticated without fault codes. The charge controller accepted the cell and climbed to full capacity without triggering a protection cutoff.
Post-install calibration on the Flex 3: After fitting, run the laptop down to hibernate cutoff under normal load — screen on, browser active — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after a cell swap.

BIOS reporting poor battery health immediately after replacement

The Flex 3 BIOS reads health data from EEPROM values stored on the previous cell. When a new cell is installed, the BIOS compares live readings against the old cell's stored profile and flags a mismatch as poor health. This is a data conflict, not a fault with the new battery. Run one complete discharge-to-hibernate followed by an uninterrupted charge to 100%. That single learn cycle overwrites the stale EEPROM baseline and clears the warning.

Laptop shuts down at 20–30% remaining after battery swap

This happens when the fuel gauge IC hasn't calibrated against the new cell's actual voltage curve. The IC still maps percentages against the old cell's discharge profile, so it calls 20–30% as the cutoff point when the new cell still has usable capacity. Under full CPU and display load, the voltage sag accelerates the miscalculation. Two to three full discharge-and-charge cycles recalibrate the IC — after that, the gauge tracks accurately and shutdowns stop well above 15V.
