About this replacement
Acer TravelMate C213Tmi Series — 11.1V Li-ion Replacement Battery (LC.BTP03.013)
This is an 11.1V 6600mAh Li-ion battery for the Acer TravelMate C213Tmi and related C200/C210 series convertible notebooks. It replaces OEM part numbers LC.BTP03.013, 3UR18650H-QC207, and 3UR18650F-3-QC151. Swap it in when the original cell no longer holds a charge or the system refuses to boot on battery alone.
- TravelMate C200/C210 series compatibility: The C213Tmi, C203ETCi, C210, and C200 share the same battery bay dimensions, connector pinout, and BMS communication protocol — that is why one cell covers the full range. The EEPROM data embedded in the replacement matches the original charge profile these systems expect.
- Bench tested on actual hardware: We cycled this battery through charge and discharge on a TravelMate-class system, confirmed the BMS handshake completed without fault codes, and verified the fuel gauge IC registered capacity within expected tolerance after three calibration cycles.
- First-install calibration on TravelMate notebooks: After fitting this cell, run the laptop down to hibernate-cutoff on battery alone, then charge uninterrupted to 100% without using the machine. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears routinely after a cell swap on this platform.
BIOS reporting battery health as poor immediately after replacement
The TravelMate BIOS reads health data from the battery's EEPROM, not from a live capacity measurement. When a new cell arrives, its EEPROM reflects factory-rated values that do not yet match the BIOS's stored discharge history from the old pack. The system flags this mismatch as poor health even though the new cell is fully functional. One complete discharge-to-hibernate followed by an uninterrupted full charge resets the learn cycle and resolves the false warning.
Laptop shuts down abruptly while the gauge still shows 20–25% remaining
This is a voltage cliff event — under combined CPU and display load, the cell voltage drops faster than the fuel gauge IC can track, and the BMS trips a hard cutoff before the displayed percentage reaches zero. It is most common in the first few cycles on a new cell because the fuel gauge IC has not yet calibrated its internal model against the new chemistry. Run three full discharge-to-hibernate cycles with normal workload active, then recharge to 100% each time. After calibration, the gauge and cutoff threshold will align and the premature shutdowns will stop.
