Lenovo ThinkPad Yoga 460 Replacement Battery SB10F46459 11.4V

Up to 20% off
New arrival
From $71.99 USD $88.99
Shipping calculated at checkout.
Fits Lenovo ThinkPad Yoga 460, ThinkPad P40 Yoga models; replaces SB10F46459, 00HW021, 00HW020, SB10F46458.
11.4V, 4200mAh Li-Polymer delivers 47.88Wh — restores full charge cycles on the Yoga 460's dual-mode display and CPU load.
Connector seats vertically into the undercarriage slot with a single locking tab; orientation is fixed, no rotation possible.
We cycled this cell on a Yoga 460 with BIOS 1.28; the BMS accepted the new pack after first insertion and held voltage stable under sustained keyboard-plus-display draw.
After installation, discharge fully to hibernation cutoff, then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.

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 ThinkPad Yoga 460 — 11.4V Li-Polymer Replacement Battery (SB10F46459)

This is an 11.4V, 4200mAh Li-Polymer replacement battery for the Lenovo ThinkPad Yoga 460 and ThinkPad P40 Yoga series. It replaces OEM part numbers SB10F46459, 00HW021, 00HW020, and SB10F46458. Capacity is 47.88Wh, matching the original cell specification.

  • ThinkPad Yoga 460 and P40 Yoga platform fit: These models share a common 11.4V three-cell Li-Polymer architecture with the same physical connector and BMS handshake protocol. The P40 Yoga variants — including 20GQ0004GE and 20GR — draw from the same battery bay specification, so one part number covers the full range.
  • Bench tested on actual hardware: We cycled this cell on a ThinkPad Yoga 460 and confirmed the BMS completed charge handshake without error. The fuel gauge IC registered capacity correctly after two calibration cycles. No thermal events or cutoff trips during discharge.
  • Post-install calibration cycle: After fitting this battery, run one full discharge to hibernate cutoff, then charge uninterrupted to 100% without unplugging mid-cycle. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on ThinkPad firmware.

Why the ThinkPad Yoga 460 reports poor battery health immediately after a cell swap

The ThinkPad BIOS stores learned charge data in EEPROM tied to the old cell's cycle count and internal resistance profile. When a new cell appears, that stored data no longer matches the actual chemistry, and the system flags it as degraded. This is not a fault with the replacement cell. Running a full discharge-to-hibernate then a full uninterrupted charge forces the BIOS to rewrite the learn cycle against the new cell. After one or two cycles, the health indicator normalises.

ThinkPad Yoga 460 shutting down at 20–30% charge shown on screen

This happens when the fuel gauge IC's stored discharge curve no longer matches the new cell's actual voltage profile. The system predicts 20–30% remaining based on old data, but the cell voltage drops below the BMS cutoff threshold sooner than expected. The fix is the same calibration sequence: discharge fully to hibernate, then charge to 100% in a single uninterrupted session. Repeat for two cycles and the fuel gauge recalibrates to the new cell's actual voltage cliff, which on this chemistry sits around 9.0V under load.

Frequently Asked Questions

My ThinkPad Yoga 460 shows "0%" or "unknown" battery immediately after fitting the new cell — is the battery dead?

No. The ThinkPad BIOS reads charge state from EEPROM data tied to the old cell, and a new cell presents values that don't match what's stored. The system cannot reconcile the difference and reports zero or unknown. Plug the laptop in, let it charge uninterrupted to 100%, then run a full discharge to hibernate — after that cycle the BIOS rewrites its stored data against the new cell and the reading normalises.

Windows says my replacement battery has a 38Wh capacity when the spec sheet lists 47.88Wh — which is correct?

The Wh figure Windows reports comes from EEPROM data the BMS carries over from the old cell, not from measuring the new cell directly. The actual rated capacity of this cell is 47.88Wh. After one full discharge-to-hibernate and a complete recharge, the fuel gauge IC recalibrates against the new chemistry and the reported Wh figure updates to reflect the actual cell rating.

The ThinkPad Yoga 460 stops charging at 80% and won't go higher — is this a fault with the replacement cell?

Almost certainly not. Lenovo ThinkPad firmware includes a BIOS-controlled charge threshold called Conservation Mode, which caps charging at 80% to reduce cell stress during long periods on AC power. Check Power Manager or Lenovo Vantage under Battery settings and confirm Conservation Mode is off. Once disabled, the next charge cycle will run to 100%.
