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,

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 Yoga S740 14 / IdeaPad S740-14IIL — 15.36V Li-Polymer Replacement Battery (L19L4PD2)

This is a 15.36V, 3950mAh (60.67Wh) Li-Polymer battery for the Lenovo Yoga S740 14 and IdeaPad S740-14IIL (81RT) ultrabook. It replaces OEM part numbers L19L4PD2, L19M4PD2, SB10W67348, SB10W67352, 5B10U97772, 5B10U97773, 5B10W67253, and 5B10W67424. If your original cell has degraded or swollen, this swap restores portable operation at the correct voltage and capacity.

  • Yoga S740-14IIL platform fit: The S740-14IIL shares one battery bay layout and connector pinout across its IIL variants. The 15.36V nominal rail and four-cell Li-Polymer configuration are fixed by the motherboard's charging IC — this cell meets that spec exactly.
  • Bench tested on actual hardware: We ran this cell in a Yoga S740-14IIL and confirmed the BMS handshake completed, charge current initiated within 30 seconds of plug-in, and the EC recognised the pack without flagging an unknown battery error.
  • Post-swap BIOS learn cycle: After fitting this cell, discharge the laptop to automatic hibernate, then charge uninterrupted to 100% before unplugging. This single cycle lets the BIOS fuel gauge IC recalibrate against the new cell and clears the false "poor health" warning that appears after every cell swap on this platform.

BIOS reporting battery health as poor immediately after replacement

The Yoga S740-14IIL stores battery state data in EEPROM on the original pack. When a new cell is fitted, the BIOS reads no charge history and flags health as poor or unknown — this is an EC firmware response, not a fault with the replacement cell. The fix is a full learn cycle: run the laptop on battery until it hibernates on its own, then charge straight to 100% without interruption. After one complete cycle, the fuel gauge IC rewrites its baseline and the health warning clears. If it persists after two cycles, check that battery conservation mode is disabled in Lenovo Vantage.

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

This is a voltage cliff issue. Under combined CPU and display load, the cell voltage drops faster than the fuel gauge IC expects — the EC reads the drop as imminent cutoff and triggers shutdown before the displayed percentage reaches zero. It happens most often in the first few cycles when the gauge hasn't mapped the new cell's discharge curve. Run two full discharge-to-hibernate cycles and the IC recalibrates its voltage-to-percentage table. After calibration, shutdowns at 20–30% shown stop; if they continue, check that the display brightness and CPU performance profile aren't both set to maximum simultaneously, which pushes draw above 25W and steepens the voltage drop.

Frequently Asked Questions

Why does Windows show the Yoga S740 battery as 0% or "unknown" right after I put the new one in?

The fuel gauge IC on this platform reads charge state from EEPROM data stored on the old pack — when a fresh cell arrives with no history, the EC reports 0% or unknown until it maps the new cell. Plug in the charger, let it reach 100%, then discharge to hibernate once without interrupting the charge. After that first full cycle, the gauge has enough data to report accurately and the unknown state clears.

Windows says my Yoga S740 battery is 60Wh but the system info screen is showing a different Wh figure — which is correct?

The EEPROM on the replacement cell holds the rated design capacity from the cell manufacturer, while Windows calculates full-charge capacity from what the charging IC actually measures during the first charge cycle. These figures diverge by a few Wh until the fuel gauge IC completes one or two calibration cycles. The physical cell in this pack is rated at 60.67Wh — trust what Windows reports after two full charge-discharge cycles, not the design capacity shown in the first few minutes after installation.

The Yoga S740 charges to 80% and then stops — is the replacement battery faulty?

Not a cell fault. Lenovo Vantage includes a "Battery Conservation Mode" setting that caps charge at 60% or 80% to reduce long-term cell stress — it stays active after a battery swap. Open Lenovo Vantage, go to Power, find Battery Settings, and switch Conservation Mode off. The laptop will then charge to 100%. If Vantage isn't installed, check the BIOS under Config → Power for a charge threshold setting and set the upper limit to 100%.
