About this replacement
Samsung P200 / P210 / P330 Series — 10.8V Li-ion Replacement Battery (AA-PBAN6AB)
This is a 10.8V, 4400mAh (47.52Wh) Li-ion battery for Samsung P200, P210, P230, and P330 series notebooks, along with 69 additional compatible models. It replaces part numbers AA-PBAN6AB, AA-PLAN6AB, and AA-PLAN9AB. It fits directly into the original bay and connects to the same BMS handshake circuit the Samsung BIOS expects.
- P200 / P210 / P230 / P330 platform fit: These Samsung notebook lines share the same 10.8V three-cell rail, identical connector pinout, and the same EEPROM communication protocol the BIOS uses to read battery state. One cell works across all four model families because the BMS handshake is identical.
- Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on a P210 unit. The BMS initialised correctly on first connection, the BIOS recognised the cell without prompting a firmware warning, and charge current tapered normally at the 4.2V-per-cell ceiling.
- First-cycle calibration on the P-series: After fitting this battery, run the laptop on battery power until it hibernates from low charge, then charge it uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on these models.
Why the Samsung P-series BIOS flags a new battery as poor health
The Samsung BIOS reads capacity and cycle data stored in the original cell's EEPROM. When a new cell arrives, that EEPROM data doesn't match the BIOS's stored baseline, so it reports degraded health even though the cell is new. This is a data mismatch, not a hardware fault. One full discharge-to-hibernate followed by an uninterrupted charge resets the learn cycle and brings the health indicator back to normal.

This happens when the fuel gauge IC hasn't yet calibrated against the new cell's actual voltage curve. The OS reads a state-of-charge percentage based on the old cell's characteristics, but the new cell hits a steeper voltage drop under full CPU and display load at that level. The system interprets the voltage cliff as empty and shuts down before the gauge catches up. Run two to three full discharge-and-charge cycles and the fuel gauge IC recalibrates — the cutoff point will shift back to the correct low-voltage threshold near 3.0V per cell.
