KAPOK 6100 Replacement Battery 10.8V 6600mAh DR202

KAPOK 6100 / 6200 Series — 10.8V Li-ion Replacement Battery (DR202 / ME202BB)

This is a 10.8V, 6600mAh (71.28Wh) lithium-ion battery for KAPOK laptops including the 6100, 6200, 6200A, and 6200M series. It uses OEM-referenced part numbers DR202, EMC36, ME202BB, NL2020, and SMP02. Install it when the original cell no longer holds charge through a normal work session.

• 6100 / 6200 platform compatibility: These models share the same 10.8V three-cell-series architecture, connector pinout, and BMS handshake protocol — which is why a single cell covers the full range. Voltage rail and thermistor signal match across all listed variants.
• Bench tested on actual hardware: We cycled this cell through charge, full discharge to BMS cutoff, and a second full charge on a 6200 unit. The BMS accepted the cell without a fault code, and the charge controller stepped through all three charging phases cleanly.
• Post-install calibration — KAPOK 6100/6200: 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 this platform.

BIOS Reporting Poor Battery Health After Swapping the 6100 Cell

The KAPOK 6100 BIOS reads health data stored in the old cell's EEPROM and compares it against the new cell's reported charge history. A fresh cell has no discharge cycles logged, so the BIOS flags it as degraded or unknown — not a fault with the cell itself. Running a full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the BIOS to rewrite the learn cycle against the new cell's actual chemistry. After two to three calibration cycles, the health indicator should normalise and reflect the true capacity of the 6600mAh cell.

Laptop Shuts Down at 20–30% Shown on the Fuel Gauge

This happens when the fuel gauge IC's charge map is still calibrated to the old, degraded cell. Under full CPU plus display load, the new cell's actual voltage curve doesn't match the IC's prediction, so the system hits a voltage cliff and cuts out before the gauge reaches zero. The fix is a full calibration cycle: discharge the laptop under normal use until it hibernates on its own, then charge uninterrupted to 100% without interrupting the session. Repeat this two to three times and the fuel gauge IC will remap its charge model to the new 10.8V cell, eliminating the early shutdown.
