About this replacement
Dell Inspiron Mini 10 Series — 11.1V Li-ion Replacement Battery (J590M)
This is an 11.1V 2200mAh Li-ion battery for the Dell Inspiron Mini 10, Mini 10v, Mini 1011, and PP19S netbooks. It replaces OEM part numbers J590M, 312-0867, 312-0931, F144M, H766N, and K711N. Fit the battery when the original no longer holds a charge or fails to power the unit away from mains.
- Mini 10 series compatibility: The Mini 10, Mini 10v, and Mini 1011 all share the same 11.1V three-cell architecture, connector pinout, and BMS communication protocol — which is why one cell works across the whole lineup.
- Bench tested on actual hardware: We ran this cell on a Mini 1011 and confirmed full BMS handshake, charge acceptance to 100%, and correct voltage reporting at the system board. The protection circuit tripped correctly at low-cell threshold.
- First-cycle reset on the Mini 10: After installing, run the netbook on battery until it hibernates from low charge, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell and clears the inaccurate health warning that appears after every cell swap.
BIOS reporting poor battery health immediately after fitting a new cell
The Dell BIOS stores battery health data in EEPROM on the old cell. When you swap cells, the BIOS reads no recognised history and flags the battery as degraded or unknown — even though the cell is new. This is not a fault with the replacement. Run one complete discharge-to-hibernate cycle followed by a full uninterrupted charge. After two or three cycles, the learn cycle completes and the health flag clears.
Mini 10 shutting down at 20–30% charge shown on screen
The fuel gauge IC on the Mini 10 calibrates against the old cell's discharge curve. A new cell with different internal resistance causes the gauge to misread remaining capacity — the display shows 25% while actual cell voltage has already hit the cutoff threshold under load. The system shuts down to protect the cell, not because the battery is faulty. Complete two full discharge-to-hibernate then charge-to-100% cycles and the fuel gauge IC will recalibrate against the new cell's actual curve. After calibration, shutdown should track accurately to below 5% remaining.
