About this replacement
Dell Latitude 15 3570 / 3560 Series — 11.1V Li-ion Replacement Battery (0098N0)
This is an 11.1V, 5200mAh (57.72Wh) lithium-ion replacement battery for the Dell Latitude 15 3570, Latitude 3560, and Latitude 3570. It replaces OEM part numbers 0098N0, 451-BBPT, VVKCY, and several cross-reference variants. Fit the battery, run a calibration cycle, and the laptop regains full portable operation away from a wall outlet.
- Latitude 3560 / 3570 platform fit: These two models share the same battery bay dimensions, connector pinout, and BMS handshake protocol. One cell covers both, with no adapter or pin modification needed.
- Bench tested on actual hardware: We ran this cell on a Latitude 3570 and confirmed the BMS handshake completed correctly, charge acceptance reached full capacity, and the protection circuit tripped at the correct over-discharge threshold without nuisance cutoffs.
- First-cycle calibration on Dell Latitude units: After installing this cell, discharge the laptop to automatic hibernate, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity 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 stored in the battery's EEPROM, not from live cell measurements. When a new cell arrives, that EEPROM data does not match the BIOS's accumulated charge history for the old pack. The system flags the mismatch as a fault. One complete discharge-to-hibernate followed by a full uninterrupted charge resets the learn cycle and clears the warning without any firmware changes.
Laptop shuts down at 20–30% battery shown on screen
This symptom points to a voltage cliff — the cell voltage drops sharply under combined CPU and display load before the fuel gauge IC expects it. The gauge IC was calibrated against the old, degraded cell and still expects its flatter discharge curve. After two or three full calibration cycles with the new cell, the gauge re-learns the voltage-to-capacity mapping and the early shutdowns stop. If the problem persists past three cycles, check the cell voltage at the connector with a meter — it should read above 10.5V at the 20% indicated mark.
