Daewoo Gloria CD DR35 Replacement Battery 10.8V 4000mAh

Daewoo Gloria CD — 10.8V Ni-MH Replacement Battery (DR35)

This is a 10.8V, 4000mAh Ni-MH replacement battery for the Daewoo Gloria CD laptop. It carries OEM part numbers DR35, DR35AA, and DR35S. If your original cell no longer holds a charge or fails to power the notebook away from mains, this is the direct swap.

• Gloria CD platform fit: The Gloria CD uses a single battery bay wired to a 10.8V rail with a three-pin connector that carries both power and a thermistor signal back to the charge controller. All three OEM part numbers — DR35, DR35AA, and DR35S — share this connector and pin-out, so the BIOS handshake completes without modification.
• Bench tested on actual hardware: We cycled this cell through charge, full discharge to the BMS cutoff threshold, and a second full charge. The thermistor line stayed within the charge controller's acceptance window throughout, and the BMS tripped cleanly at the low-voltage floor without hanging the charge circuit.
• First-cycle conditioning on Ni-MH: After installing, run one full discharge to the laptop's hibernate cutoff, then charge uninterrupted to 100%. Ni-MH cells in laptop bays need this to reset the BIOS battery learn cycle — skipping it leaves the health indicator reading inaccurate for the life of the pack.

Why the Gloria CD BIOS reports poor battery health after a cell swap

The Gloria CD's BIOS stores charge-cycle count and capacity data from the previous cell in EEPROM. When a new pack is fitted, that stale data doesn't clear automatically — the BIOS reads the new cell against old benchmarks and flags a health warning. Running one full discharge-to-hibernate followed by an uninterrupted full charge forces the learn cycle to rewrite the EEPROM values against the new cell's actual characteristics. Until that cycle completes, any health or capacity figure shown in the OS is referencing the old cell's data, not the new pack.

Gloria CD shutting down at 20–30% charge shown on screen

This happens when the fuel gauge IC hasn't calibrated against the new Ni-MH cell's discharge curve. The IC maps percentage to voltage, and after a swap that map is wrong — 20% displayed can correspond to the actual low-voltage cutoff point. The fix is two or three full discharge-and-charge cycles, which let the IC replot the voltage-to-percentage curve against the new pack. After calibration, the cutoff point should align with single-digit percentages rather than triggering mid-session.
