Dell Latitude 7200 2-in-1 Replacement Battery 7.6V 4650mAh

Dell Latitude 7200 2-in-1 — 7.6V Li-Polymer Replacement Battery (09NTKM)

This 7.6V, 4650mAh (35.34Wh) lithium-polymer cell replaces the original battery in the Dell Latitude 7200 2-in-1 and Latitude 12 7200. It matches the OEM voltage rail, physical footprint (194.16 × 102.90 × 4.25mm), and connector pinout exactly. Install it when the original cell no longer holds charge or the system reports degraded battery health.

• Latitude 7200 2-in-1 and Latitude 12 7200 fit: Both models share the same chassis depth, battery bay dimensions, and SMBus communication protocol. The BMS handshake uses the same five-pin connector and EEPROM data structure, so a single cell works across the full platform without wiring changes.
• Bench tested on actual hardware: We ran this cell on a Latitude 7200 2-in-1 and confirmed full SMBus communication, correct voltage recognition at 7.6V nominal, and stable BMS charge cycling from cutoff through to 100% without thermal events or mid-cycle drops.
• Post-install calibration on Dell Latitude hardware: After fitting this cell, run one full discharge to hibernate-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 Dell SMBus-managed platforms.

BIOS reporting battery health as poor immediately after replacement

Dell's BIOS reads health data from EEPROM registers stored on the battery controller, not from live cell voltage. A new cell ships with factory EEPROM values that the BIOS interprets as a mismatch against its stored history for the old cell. The result is a "Battery health is poor" or "Consider replacing your battery" alert even when the new cell is fully functional. Running a complete discharge-to-hibernate followed by an uninterrupted full charge forces the BIOS to write a new baseline and clears the warning.

System info shows wrong Wh rating after battery swap

Windows and Dell's own diagnostics pull the Wh figure from the battery's EEPROM design-capacity register, which may differ slightly from the real-world chemistry capacity of the replacement cell. This is a data-field discrepancy, not a fault with the cell itself. The fuel gauge IC recalibrates its Wh tracking against actual charge throughput over two to three full cycles. After those cycles, the reported Wh figure stabilises and aligns with the 35.34Wh rating of this cell.
