About this replacement
Lenovo ThinkPad E470 Series — 10.95V Li-Polymer Replacement Battery (SB10K97568)
This 10.95V lithium-polymer battery replaces the original cell in the Lenovo ThinkPad E470, E470C, and E475 notebooks. Capacity is 4100mAh (44.9Wh), matching the stock specification. It covers OEM part numbers SB10K97568, SB10K97569, 01AV411, 01AV412, and 01AV413.
- ThinkPad E470 and E475 platform fit: The E470, E470C, and E475 share the same battery bay dimensions, connector pinout, and BMS communication protocol. One cell revision covers all three chassis variants without modification.
- Bench tested on actual hardware: We ran this cell on a ThinkPad E470 and confirmed the BMS handshake completed correctly. The BIOS recognised the battery, charge current ramped normally, and no error flags appeared in Lenovo Vantage diagnostics.
- First-cycle calibration after install: After fitting this cell, run one full discharge until the laptop hibernates, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on ThinkPad hardware.
BIOS reporting poor battery health immediately after replacement
ThinkPad firmware reads battery health from EEPROM data written by the previous cell. When a new cell installs, that stored data does not match the fresh chemistry, so the BIOS flags poor health before any charge cycle runs. This is a data mismatch, not a fault with the new cell. Running the full discharge-to-hibernate then charge-to-100% sequence lets the fuel gauge IC write fresh calibration data to memory. After one or two full cycles, Lenovo Vantage and the BIOS health readout will reflect the actual cell state.
Laptop shuts down at 20–30% charge shown on screen
This happens when the fuel gauge IC is still calibrated against the old, degraded cell and does not yet know the voltage curve of the new one. Under full CPU and display load, voltage drops faster than the uncalibrated gauge predicts, and the laptop reaches the low-voltage cutoff before the percentage reaches zero. The fix is the same calibration cycle: discharge fully to hibernate, then charge to 100% without interruption. After two full cycles the gauge maps the new cell's voltage curve correctly and the premature shutdown stops. Check that the battery percentage at hibernate sits below 5% before starting the second cycle.
