About this replacement
Dell Precision 15 3580 — 11.4V Li-Polymer Replacement Battery (GRWKG)
This is an 11.4V, 3650mAh (41.61Wh) Li-Polymer battery for the Dell Precision 15 3580 mobile workstation. It replaces OEM part numbers GRWKG, NKXK7, and V7TXF. The 3580 is a professional workstation built for engineering and design work — battery health matters when you're unplugged on a deadline.
- Precision 15 3580 compatibility — all three sub-models: The base 3580, the 5CHPK, and the JHH2C variants all run the same 11.4V three-cell Li-Polymer battery with identical connector pinout and BMS handshake. No hardware differences affect fitment across those sub-models.
- Bench tested on actual hardware: We ran charge and discharge cycles on the 3580 platform. The BMS communicated correctly over SMBus, the fuel gauge IC updated state-of-charge without error flags, and the cell held stable voltage through sustained CPU and display load.
- BIOS learn cycle after installation: After fitting this battery, run a 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 battery health as poor after replacing the cell on the 3580
The Precision 3580 BIOS reads health data from the battery's EEPROM. When a new cell goes in, the EEPROM values don't match the charge history the BIOS expects. This triggers a false "battery health poor" or "consider replacing" alert immediately after swapping. It is not a fault in the replacement cell. Run one full discharge-to-hibernate then a full uninterrupted charge — this allows the BIOS learn cycle to write new baseline data and the alert clears on the next boot.
Laptop shuts down at 20–30% remaining on the 3580 after battery swap
This happens when the fuel gauge IC hasn't calibrated against the new cell's actual voltage curve. The OS reads 25% but the cell voltage has already crossed the cutoff threshold under sustained CPU and display load — the workstation shuts down to protect the cell. The fuel gauge needs two to three full discharge-and-charge cycles to map the new cell's voltage profile accurately. Run those calibration cycles before drawing heavy load in the field. After calibration, the shutoff point should align with the displayed percentage at roughly 3.2V per cell.
