Battery Care Tips
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
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 720-13IKB / 730-13IKB — 7.68V Li-Polymer Replacement Battery (L16L4PB1)
This 7.68V, 6000mAh (46.08Wh) lithium-polymer cell replaces the original battery in the Lenovo Yoga 720-13IKB and Yoga 730-13IKB 13-inch convertible ultrabooks. It fits the full compatibility range including 80X6006QAU, 81CT007CAU, 81CT005NMZ, and 81C3002MGE variants. OEM part numbers covered include L16L4PB1, L16M4PB1, L16C4PB1, 5B10M52211, 5B10M52740, 5B10Q38238, 5B10W67229, and SB10W6727.
- Yoga 720 and 730 shared battery platform: Both the 720-13IKB and 730-13IKB series use the same 7.68V two-cell Li-Polymer configuration, identical connector pinout, and the same BMS handshake protocol — so one cell fits the entire platform without modification.
- Bench tested on actual hardware: We ran this cell on a Yoga 720-13IKB. The BMS accepted the new cell without fault codes, charge current stepped correctly from bulk to CV phase, and the fuel gauge IC began tracking state-of-charge within one full cycle.
- Post-install calibration tip for Yoga convertibles: After fitting, run the laptop off battery until it hibernates at 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 on this platform.
BIOS reporting battery health as poor immediately after replacement
The Yoga 720 and 730 store battery health data in EEPROM on the old cell. When a new cell goes in, the BIOS reads zero charge cycles and a full-capacity rating it hasn't verified yet — so it flags health as unknown or poor. This is not a fault with the new cell. Run one full discharge-to-hibernate cycle followed by a full uninterrupted charge. The BIOS battery learn cycle rewrites the EEPROM baseline against the new cell chemistry and the health warning clears.
Laptop shutting down at 20–30% shown on the fuel gauge
This happens when the fuel gauge IC hasn't calibrated against the new cell yet. The gauge is estimating state-of-charge based on the old cell's discharge curve, so it reads 25% while the actual cell voltage has already hit the BMS cutoff floor near 6.0V under load. The fix is two to three full discharge-and-charge cycles so the fuel gauge IC maps the new cell's actual voltage curve. After calibration, the percentage readout and the real cutoff point will line up correctly.

Frequently Asked Questions
My Lenovo Yoga 720 shows the wrong Wh rating in the battery info screen after fitting this replacement — is the cell actually smaller than advertised?
No. The Wh figure shown in Windows or Lenovo Vantage pulls from EEPROM data written to the original cell at the factory. The new cell's EEPROM carries its own rated chemistry values, which may differ slightly from the old cell's logged data. The actual capacity is 46.08Wh as rated. Run one full calibration cycle — full discharge to hibernate, then full charge to 100% — and the reported figure will stabilise against the new cell's real chemistry.
The replacement battery charges to about 80% then stops — the Yoga 720 won't charge past that point no matter how long it stays plugged in.
This is almost always the BIOS-controlled charge limit in Lenovo Vantage, not a fault with the cell itself. Lenovo ships many Yoga units with "Conservation Mode" enabled, which caps charging at 55–80% to reduce long-term cell stress. Open Lenovo Vantage, go to Power, then Battery Settings, and switch from Conservation Mode to Normal Mode. The battery will then charge to 100%.
The fuel gauge on my Yoga 730 jumps wildly — showing 60%, then 45%, then 70% within minutes of unplugging.
The fuel gauge IC recalculates state-of-charge using discharge curve data from the original cell. A new cell has a slightly different voltage-to-capacity curve, so the IC loses tracking and the percentage reading bounces. This settles after two to three complete discharge-and-charge cycles that let the IC map the new curve. Do not interrupt the cycles mid-charge — run each one fully from hibernate cutoff back to 100%.
