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 IdeaPad G460 — 11.1V Li-ion Replacement Battery (121000935)
This 11.1V, 6600mAh (73.26Wh) Li-ion battery replaces the original cell in the Lenovo IdeaPad G460 and its close variants, including the B470, B470A, and B470G series. It matches the OEM voltage rail and connector spec. Install it when the original cell can no longer hold a useful charge through a normal work session.
- G460 and B470 series fit: These models share the same 11.1V three-cell-series battery bay, connector pinout, and BMS communication protocol. That's why one cell covers all of them. Compatibility is electrical, not cosmetic.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on an IdeaPad G460 unit. The BMS handshake completed without error flags, charge termination triggered correctly at full voltage, and the protection circuit tripped at the expected undervoltage threshold.
- Post-install calibration cycle: After fitting this battery, run the laptop down until it hibernates on its own, then charge it uninterrupted to 100% without using the machine. This resets the BIOS battery learn cycle and clears the false health warning that appears after every cell swap.
BIOS reporting poor battery health immediately after replacement
The IdeaPad G460 BIOS reads EEPROM data written by the previous cell — cycle count, charge history, and health estimates stored in the old battery's firmware. When a new cell arrives with fresh EEPROM values, the BIOS flags a mismatch and displays a health warning. This is not a fault with the replacement cell. Run one full discharge-to-hibernate followed by a single uninterrupted charge to 100%, and the BIOS learn cycle will overwrite the stale data with readings from the new cell.
Laptop shutting down at 20–30% charge shown on screen
This happens when the fuel gauge IC still references calibration data from the old cell. The percentage shown on screen is calculated from a capacity model that no longer matches the new chemistry. Under full CPU and display load, the actual cell voltage drops faster than the gauge predicts, and the system hits the low-voltage cutoff before the display reaches 0%. Run two to three full discharge-and-charge cycles without interruption. After that, the fuel gauge IC recalibrates against the new cell's actual voltage curve and the shutdowns stop. Target a resting voltage of 12.5–12.6V at the "full" reading to confirm the gauge has settled.

Frequently Asked Questions
Why does my IdeaPad G460 say "consider replacing your battery" straight after I put in a new cell?
The BIOS reads EEPROM data embedded in the battery's firmware — cycle count, charge history, and rated health from the previous cell. A new cell arrives with values the BIOS doesn't recognise as "healthy" yet, so it throws the warning immediately. Run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. That single learn cycle rewrites the BIOS health estimate against the new cell and clears the warning.
The battery percentage in Windows is jumping around — it shows 60%, then skips to 35% without warning. What's wrong?
The fuel gauge IC inside the laptop is still using its calibration map from the old cell. The new cell has a slightly different voltage-versus-capacity curve, so the percentage readings are inaccurate until the IC recalibrates. Run two to three full discharge-to-hibernate and uninterrupted full-charge cycles. After those cycles the fuel gauge IC builds a new internal model against the actual cell, and the percentage readout stabilises.
System information shows the wrong Wh rating — 48Wh instead of 73Wh. Is this cell defective?
The Wh figure in system info is pulled from the EEPROM on the battery itself, not measured live. Some replacement cells ship with EEPROM values that reflect a different capacity variant in the same product family — the physical cell chemistry is correct, but the stored metadata doesn't match. Confirm the actual cell is performing normally by checking that resting voltage reads between 12.4V and 12.6V at full charge. If voltage is in that range, the cell is fine and the Wh display discrepancy is a metadata mismatch only.
