Installation & Handling Tips
- Expert Tip for Slim Chassis: The Notebook 9 series uses an extremely thin magnesium alloy bottom panel. Use a precision screwdriver and handle the panel gently to prevent any warping or bending during the battery swap.
- Connector Security: Ensure the battery ribbon cable is fully inserted and the latch (if applicable) is secured. A slight misalignment can cause the system to fail to recognize the battery.
- Calibration: After installation, charge the battery to 100% and then discharge to 10% for the first 2-3 cycles. This helps the OS accurately calculate the remaining runtime on these high-density cells.
Frequently Asked Questions
Q: Will this fit the Notebook 9 Spin (940X3L)?
A: No. The **940X3L Spin** (convertible) uses a larger 39Wh battery (AA-PBUN4AR). This **AA-PBUN2LT** (30Wh) is only for the standard clamshell 900X3L/M series.
Q: Why is the capacity 30Wh instead of higher?
A: This is the original specification for the ultra-lightweight NP900X3L series, which weighs only about 1.9 lbs. Samsung prioritized extreme weight reduction, and this 30Wh unit is the exact direct replacement.
