Important Shipping Notice (Chinese New Year 2026 - Batteries)

Estimated Battery Delivery Time
Please allow up to 30 days for delivery during this period.

If You Need a Battery ASAP
We completely understand that a working laptop is time-sensitive. If you need a battery urgently, please order with caution. For the fastest solution, you may prefer a local seller or another supplier that is not impacted during the holiday season. While we are sorry we may not be the quickest option for urgent cases, we will be genuinely happy if you can get your problem solved sooner.

If You are Not in a Hurry
If you can wait, you can place your order with confidence. It is very common to keep using a laptop with reduced battery runtime by plugging it in when needed.

Installation & Maintenance Guide

Internal Security: This is an internal battery. Replacing it requires unscrewing the bottom panel. Use a precision screwdriver and non-conductive prying tools to protect the internal motherboard and magnesium-aluminum chassis.
Connector Precautions: Ensure the battery flex cable is perfectly aligned with the motherboard socket before pressing it down. A slanted connection can result in the system failing to recognize the battery.
Battery Calibration: For optimal performance, charge the new battery to 100% and then allow it to discharge to 10% for the first 2-3 cycles. This helps the system accurately calibrate the 15.4V fuel gauge.

Frequently Asked Questions

Q: Will this fit the standard Galaxy Book Pro or Ultra?

A: No. Pro and Ultra models use different high-capacity batteries (63Wh or 76Wh). This AA-PBSN4AF (54Wh) is designed for the standard Galaxy Book and Flex Alpha series.

Q: My original battery color is black, but this one is white. Is it compatible?

A: Yes. Samsung uses both black and white casing for the internal cells depending on the manufacturing batch. As long as the AA-PBSN4AF part number matches, it is 100% compatible.
