About this replacement
Dell Inspiron Mini 10 / 1011 / 10v — 11.1V Li-ion Replacement Battery (312-0867)
This is an 11.1V, 4400mAh (48.84Wh) Li-ion battery for the Dell Inspiron Mini 10, Mini 1011, Mini 10v, and PP19S netbook series. It replaces OEM part numbers 312-0867, 312-0931, 312-0935, F144M, H766N, J590M, J658N, M457P, and K711N. Physical dimensions are 203.71 × 46.97 × 36.19mm — verify against your existing cell before installing.
- Mini 10 series compatibility: The Mini 10, Mini 1011, and Mini 10v all run the same 11.1V three-cell architecture with an identical connector pinout and BMS handshake protocol. That shared platform is why one cell covers the full range.
- Bench tested on actual hardware: We ran this cell through charge, discharge, and BMS communication checks on a Mini 10 unit. The BMS handshake completed without fault codes, and charge acceptance held steady across three consecutive cycles.
- First-install calibration on the Inspiron Mini 10: After fitting this cell, run one full discharge to hibernate cutoff — do not interrupt it. Then charge uninterrupted to 100%. This single learn cycle resets the BIOS fuel gauge against the new cell chemistry and clears the false "poor health" flag that almost always appears after a cell swap on this platform.
BIOS reporting poor battery health after swapping the Mini 10 cell
The Mini 10 BIOS stores learned capacity data in EEPROM from the previous cell. When a new cell goes in, that stored data no longer matches actual cell behaviour, so the BIOS flags health as poor or unknown. This is a firmware state, not a defect in the replacement cell. Running one complete discharge-to-hibernate followed by an uninterrupted full charge forces the BIOS to rewrite its learned capacity values against the new chemistry. After that cycle, health status should read normal.

This happens when the fuel gauge IC has not yet calibrated against the new cell — its state-of-charge map still reflects the old, degraded cell's voltage curve. Under combined CPU and display load, the new cell hits a voltage profile the uncalibrated gauge misreads as near-empty, triggering an early shutdown. The fix is the same learn cycle: discharge fully to hibernate, then charge to 100% without interruption. After two to three of these cycles, the gauge recalibrates and the cutoff point moves back to the correct low-voltage threshold near 10.5V.
