Dell Inspiron 11 3000 7.6V Replacement Battery 0JV6J 4000mAh

Dell Inspiron 11 3000 Series — 7.6V Li-ion Replacement Battery (0JV6J)

This is a 7.6V, 4000mAh (30.4Wh) Li-ion replacement battery for the Dell Inspiron 11 3000 series. It fits the Inspiron 11 3162, 3153, 3148, and over 40 additional models in the 3000 line. The battery restores portable operation when the original cell can no longer hold a usable charge.

• Inspiron 11 3000 platform fit: Every model in this line runs the same 7.6V two-cell architecture with a common connector and BMS handshake protocol. OEM part numbers 0JV6J, PGYK5, GK5KY, and 8NWF3 all cross to this cell — Dell used multiple part numbers across production runs of the same physical battery.
• Bench tested on actual hardware: We ran this cell in an Inspiron 11 3162 and monitored BMS communication through the charge cycle. The protection circuit engaged correctly at full charge and the fuel gauge IC recognised the cell without a manual reset on first boot.
• BIOS learn cycle after install: After fitting this battery, run the laptop on battery until it hits hibernate cutoff, then charge uninterrupted to 100%. This single full cycle resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.

BIOS reporting poor battery health immediately after replacement

Dell's BIOS reads health data from EEPROM stored in the old battery's BMS — not from the new cell's actual charge state. When the old cell is removed, that EEPROM data is gone. The BIOS then flags the new battery as unknown or degraded because it has no historical data to reference. Run one full discharge-to-hibernate and one uninterrupted charge-to-100% to let the BIOS write a fresh baseline to the new cell's EEPROM.

This happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The IC is still using discharge tables from the degraded original battery, so it miscalculates the remaining capacity and triggers shutdown well before the cell is actually depleted. The fix is two to three complete discharge and charge cycles — each one gives the IC more accurate data points. After the third cycle, the reported percentage and actual cutoff voltage should align within a few percent.
