Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Lenovo ThinkPad X13 Yoga G2 — 11.58V Li-Polymer Replacement Battery (5B11A13107)

This 11.58V, 4500mAh (52.11Wh) lithium-polymer cell replaces the internal battery in the Lenovo ThinkPad X13 Yoga G2 convertible laptop. It fits all X13 Yoga G2 variants, including the 20W8000TGE, 20W8001JCK, and 20W8001WAU, among 49 additional sub-models. Cross-references include OEM part numbers 5B11A13107, 5B11M90077, L20M3P71, and SB11A13105.

  • X13 Yoga G2 platform fit: All X13 Yoga G2 variants share the same 11.58V three-cell Li-Polymer configuration, connector pinout, and BMS communication protocol — so one cell covers the full model spread without modification.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on a ThinkPad X13 Yoga G2 unit. The BMS handshake completed correctly, charge termination triggered at full capacity, and the fuel gauge IC reported the correct Wh rating in Lenovo Vantage after two calibration cycles.
  • Post-install calibration step: After fitting, run the laptop down to hibernate cutoff on a real workload — not idle — 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 ThinkPad firmware.

BIOS reporting poor battery health immediately after replacement

ThinkPad firmware stores battery health data in the EEPROM of the original cell. When a new cell is fitted, the BIOS reads no prior cycle history and flags the battery as degraded or unknown — this is a firmware artefact, not a fault with the replacement. The fix is a full battery learn cycle: discharge to hibernate, then charge to 100% without interruption. After one to two full cycles, the BIOS recalibrates its health estimate against the new cell's actual voltage curve and clears the warning.

Laptop shuts down at 20–30% charge shown on screen

This happens when the fuel gauge IC has not yet mapped the new cell's voltage-to-capacity curve. The old cell's discharge profile is still cached, so the reported percentage does not match the actual cell voltage — the laptop hits the low-voltage cutoff while the gauge still shows charge remaining. Run two full discharge-to-hibernate cycles to force the IC to recalibrate against the new chemistry. After calibration, the shutdown threshold aligns with the displayed percentage, and the gauge stabilises at roughly 3.0V per cell at the true cutoff point.

Frequently Asked Questions

Why does Lenovo Vantage show the wrong Wh rating after I installed the new battery?

The Wh figure displayed in Lenovo Vantage is pulled from EEPROM data written by the original cell's BMS. When the new cell is first installed, the fuel gauge IC has not yet completed a learn cycle against the actual chemistry, so it reports the rated value from the old cell's stored profile rather than the true capacity of the new one. Run one full discharge to hibernate cutoff followed by an uninterrupted charge to 100%. After that cycle, Vantage will read 52.11Wh, which matches the new cell's actual rating.

The X13 Yoga G2 stops charging at 80% — is the battery faulty?

This is almost always a BIOS-controlled charge threshold, not a cell fault. Lenovo ships ThinkPads with a Conservation Mode enabled by default in Lenovo Vantage, which caps charging at 80% to reduce long-term cell stress. Open Lenovo Vantage, go to Power, then Battery, and switch from Conservation Mode to Normal Mode. The battery will then charge to 100%.

The fuel gauge jumps around wildly for the first few charges — what is causing that?

The fuel gauge IC on the X13 Yoga G2 builds its capacity model from the first few discharge cycles. Until it has enough data points from the new cell's voltage curve, percentage readings will be erratic — jumping from 60% to 40% or spiking briefly before settling. This is not a wiring or BMS fault. Complete two full discharge-to-hibernate cycles with a consistent workload, such as video playback at full brightness, then recharge to 100% each time. The gauge stabilises once the IC has mapped the new cell's curve.
