About this replacement
ECS G730 / Green 732 — 14.8V Li-ion Replacement Battery (LIP-X036)
This is a 14.8V, 6600mAh (97.68Wh) Li-ion replacement battery for the ECS G730 and Green 732 laptops. It slots into the original battery bay and connects to the same charge controller the factory cell used. Install it when the original pack no longer holds enough charge for untethered use.
- G730 and Green 732 compatibility: Both models share the same 14.8V four-cell series configuration and the same LIP-X036 connector pinout. The BMS handshake on this replacement matches the charge controller spec on both platforms, so no adapter or firmware workaround is needed.
- Bench tested on actual hardware: We cycled this cell on a G730 unit under sustained CPU and display load. The BMS held the 14.8V nominal rail without triggering an early protection cutoff, and charge termination occurred cleanly at full capacity.
- First-cycle recalibration on the G730: After installing, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the false low-health warning that appears after every cell swap on this platform.
BIOS reporting battery health as poor after installing the LIP-X036
The G730 BIOS reads health data from EEPROM registers on the battery pack. When a new cell arrives, those registers don't match the learned values from the old pack, so the BIOS flags health as poor or unknown. This is not a fault with the replacement cell. Run one full discharge-to-hibernate followed by an uninterrupted charge to 100% — this triggers the battery learn cycle and rewrites the BIOS health registers against the new cell's actual data.
Laptop shuts down at 20–30% charge shown on screen
This happens when the fuel gauge IC hasn't calibrated against the new cell yet. The OS shows 25% remaining, but the actual cell voltage has already dropped below the BMS cutoff threshold under full CPU and display load — so the laptop cuts out. It's a calibration gap, not a defective battery. Complete two or three full discharge-to-hibernate and full-charge cycles to allow the fuel gauge IC to map the new cell's voltage curve accurately. After calibration, the displayed percentage will track the real remaining charge.
