Lenovo IdeaPad Yoga 11 L11M4P13 Compatible Battery 14.8V

Up to 18% off
New arrival
From $125.99 USD $152.99
Shipping calculated at checkout.
Fits Lenovo IdeaPad Yoga 11 and Yoga 11S models, replaces OEM part L11M4P13.
14.8V and 2840mAh capacity sustains the Yoga 11's hybrid convertible operation under CPU plus display load.
Connector seats flush into the battery slot with a single locking tab — no adapter needed.
We bench-tested this cell on a Yoga 11S; the BMS accepted full charge without cutoff and held voltage under sustained draw.
After installation, run one full discharge to hibernation-cutoff then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears the inaccurate health warning.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,
Michael

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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 IdeaPad Yoga 11 Series — 14.8V Li-Polymer Replacement Battery (L11M4P13)

This is a 14.8V, 2840mAh Li-Polymer replacement battery for the Lenovo IdeaPad Yoga 11 and Yoga 11S convertible notebook line. It uses OEM part number L11M4P13 and fits the hinge-based 360° convertible form factor where the battery sits flat across the lower chassis. Voltage and capacity match the original Lenovo specification exactly.

  • Yoga 11 and 11S platform fit: These models share the same 14.8V four-cell Li-Polymer battery rail, connector pinout, and BMS handshake protocol. The Yoga11S-IFI and Yoga11S-IFI(U) variants use the same L11M4P13 cell configuration, so one part number covers the full series without modification.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on Yoga 11S hardware. The BMS negotiated correctly with the Lenovo EC firmware, reported accurate State of Charge data, and held stable voltage under combined CPU and display load without tripping an early cutoff.
  • BIOS battery learn cycle after install: After fitting this cell, run the laptop down to hibernate cutoff under normal load, then charge uninterrupted to 100%. This forces the BIOS to run a full learn cycle against the new cell and clears the inaccurate health warning that appears after every cell swap.

Yoga 11 shutting down at 20–30% remaining after battery swap

This happens because the fuel gauge IC is still calibrated to the discharge curve of the old, degraded cell. When the new cell hits a voltage zone the IC associates with depletion, it signals a forced shutdown — even though real capacity remains. The fix is two to three full discharge-to-hibernate and uninterrupted-charge cycles. After that, the fuel gauge IC recalibrates its curve to the new cell chemistry and the early shutdowns stop.

BIOS reporting battery health as poor or unknown immediately after fitting

The Lenovo BIOS reads health data from the EEPROM embedded in the battery's BMS circuit. A new cell ships with factory EEPROM values that do not match the accumulated cycle data the BIOS was tracking on the old cell, so it flags the reading as poor or unknown. This is not a fault with the replacement cell. Run one full discharge-to-hibernate followed by a complete charge to 100% — the BIOS learn cycle will write fresh baseline values to the EEPROM and the health warning will clear.

Frequently Asked Questions

My Lenovo Yoga 11S shows the new battery as 0% or "plugged in, not charging" right after fitting — what's wrong?

The Lenovo EC firmware occasionally loses handshake with a new cell if the old battery was fully depleted before removal. Hold the power button for 30 seconds with the battery seated and the charger disconnected to drain residual capacitor charge, then reconnect the charger before powering on. This forces the EC to re-initialise the charge circuit and recognise the new cell. If the reading stays at 0%, check that the flat cable connector on the battery is fully seated — a partial connection on the Yoga 11 chassis is a common install error.

The Wh rating shown in Windows Battery Report says 38Wh but the replacement battery is listed as 42Wh — is the cell faulty?

The Windows Battery Report pulls the Wh figure from the EEPROM on the battery's BMS board, which stores the factory design capacity of the original Lenovo cell. Until the BIOS completes a full learn cycle against the new cell, it continues reporting the old EEPROM rated value rather than the actual chemistry capacity. Run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. The reported Wh figure in Windows will update to reflect the new cell after the learn cycle completes.

After two weeks of use the Yoga 11 fuel gauge reads differently every morning — jumping between 60% and 85% on startup — is the battery defective?

This is fuel gauge IC drift, not a cell defect. The IC loses its voltage-to-capacity reference point when the laptop is put to sleep at a mid-state charge repeatedly without completing a full cycle. The IC has not had enough full-range data to build an accurate discharge curve for the new cell. Run two consecutive full discharge-to-hibernate cycles followed by uninterrupted charges to 100%, and the gauge will stabilise. After calibration, the variance on startup should drop to within 2–3%.
