LG 13Z980 Replacement Battery 7.7V 9350mAh LBS1224E

Up to 18% off
New arrival
From $113.99 USD $136.99
Shipping calculated at checkout.
Fits LG 13Z980, 13Z990, and related ultrabook models; replaces OEM part number LBS1224E.
7.7V and 9350mAh (72Wh) capacity restores full charge cycles to aging packs that no longer hold voltage under sustained CPU and display load.
Connector and orientation match the original battery slot; no adapter needed, no mechanical modification to the ultrabook chassis required.
We bench tested the LBS1224E pack through five full discharge cycles; the BMS held voltage stable until cutoff and accepted charge without fault codes or throttling.
After installation, run one full discharge to hibernate cutoff, then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears inaccurate health warnings.

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.

LG 13Z980 / 13Z990 Series — 7.7V Li-Polymer Replacement Battery (LBS1224E)

This is a 7.7V, 9350mAh (72Wh) lithium-polymer replacement battery for the LG 13Z980 and 13Z990 ultrabook series. It uses OEM part number LBS1224E and fits a wide range of 13Z990 variants including the AA33C and AA53C configurations. If your original cell is no longer holding charge or the OS reports degraded health, this replaces it directly.

  • 13Z980 and 13Z990 platform fit: Both models share the same 7.7V Li-Polymer cell format, connector pinout, and BMS communication protocol. The battery management system handshakes over the same SMBus line, so the same cell works across the full 13Z990 variant range without modification.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the 13Z990 platform. The BMS accepted the cell without rejection errors, charge terminated correctly at 100%, and the protection circuit responded accurately to load spikes during CPU stress testing.
  • Post-install calibration on the LG 13Z series: After fitting this cell, run the laptop down to hibernate-cutoff under normal use, 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 poor battery health immediately after fitting the LBS1224E

The LG 13Z series stores battery health data in EEPROM on the old cell. When a new cell is installed, the BIOS reads zero cycle history and flags it as degraded or unknown — this is a data mismatch, not a fault with the new cell. The fuel gauge IC has not yet calibrated against the new cell's actual chemistry. Run one complete discharge-to-hibernate cycle followed by a full uninterrupted charge to 100%. After two to three cycles, the health indicator normalises and the BIOS learn cycle completes.

Laptop shuts down at 20–30% shown on the LG 13Z990

This happens when the fuel gauge IC is still calibrated against the old cell's voltage curve. The new LBS1224E cell has a different discharge profile, so the gauge misjudges remaining capacity and triggers shutdown early. It is not a cell defect — the IC needs to relearn the cutoff voltage, which sits at approximately 6.0V under load for this 7.7V nominal cell. Force a full discharge to hibernate, then charge uninterrupted to 100% twice in a row to let the gauge IC recalibrate against the new curve.

Frequently Asked Questions

The LG 13Z990 shows the wrong Wh rating in system info after fitting the new battery — it says 57Wh instead of 72Wh. Is the cell faulty?

The Wh figure shown in system info is read from EEPROM data stored on the original cell, not measured from the new one. After a cell swap, the OS often pulls the old cell's rated Wh from cached firmware data until the fuel gauge IC recalibrates. Run two full discharge-to-100% charge cycles and the system will update its reading to reflect the actual 72Wh capacity of the LBS1224E.

The new LBS1224E stops charging at 80% and won't go higher — is this a defective cell?

This is a BIOS-controlled charge limit, not a battery fault. LG's firmware on some 13Z series units ships with a battery care setting enabled that caps charge at 80% to reduce long-term cell wear. Open the LG Control Center application, navigate to the battery section, and disable the charge limit or switch to full charge mode. The cell itself charges to 100% — the 80% ceiling is enforced entirely in firmware.

The fuel gauge on the LG 13Z980 reads 100% for a long stretch then drops suddenly to 15% — why is it so inaccurate right after the swap?

The fuel gauge IC on the 13Z980 stores a charge model built from the old cell's impedance and voltage curve data. A new LBS1224E cell has a different internal resistance profile, so the IC's predictions are wrong until it collects new data. This erratic reading is normal for the first two to three cycles. Run the laptop down to hibernate-cutoff under real workload — not sleep — then charge fully to 100% without interruption, and repeat once more to let the gauge IC rebuild its model against the new cell.
