Installation & Care Tips
- Internal Safety: This is an internal battery. Accessing it requires removing the bottom panel. Use a high-quality screwdriver and plastic pry tools to avoid damaging the premium aluminum or magnesium-lithium chassis.
- Precise Fitting: The Galaxy Book Ion and Flex series have extremely tight internal tolerances. Ensure the battery lies perfectly flat and the connector is securely seated before replacing the back cover.
- Initial Calibration: After installation, charge the battery to 100% and then allow it to discharge to 10% for the first 2-3 cycles. This synchronizes the Windows power management system with the new 15.44V cells.
Frequently Asked Questions
Q: Will this fit the newer Galaxy Book Pro or Book2 series?
A: No. The Pro and Book2/3/4 series use different battery part numbers (like AA-PBMN4VN). This AA-PBRN4ZU is specific to the original Flex and Ion generation.
Q: Is it safe for the Ion 15.6-inch model which has a second SSD slot?
A: Absolutely. This battery is designed to fit the 15.6″ Ion (NP950XCJ) without interfering with the secondary storage expansion slots.
