Important Shipping Notice (Chinese New Year 2026 - Batteries)
During the Chinese New Year 2026 holiday period, laptop battery orders may take longer than usual to deliver. This delay is mainly caused by battery sourcing (most laptop batteries are manufactured in China) and holiday logistics congestion.

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. We will ship as soon as sourcing and logistics allow, keep your order moving, and deliver a high-quality, reliable battery that fits your device properly.

Thank you for your understanding and support.

Installation & Care Tips

Internal Safety: This is an internal battery. Replacing it requires removing the laptop’s bottom case. Ensure the device is fully powered off and use non-conductive tools to avoid static discharge.
Flex Cable Alignment: The Galaxy Book Go uses sensitive ribbon cables. Ensure the battery connector is perfectly aligned and firmly seated into the motherboard socket before securing the screws.
Initial Conditioning: For new polymer cells, charge the battery to 100% and then allow it to discharge to 10% for the first 2-3 cycles to calibrate the system’s fuel gauge.

Frequently Asked Questions

Q: Is this battery compatible with the Galaxy Book Pro or Pro 360?

A: No. This battery is designed exclusively for the Galaxy Book Go series. The Pro and Pro 360 models use a different internal battery architecture.

Q: Why is the voltage 7.72V instead of the common 7.6V?

A: 7.72V is the specific nominal voltage for the high-density cells used in the Book Go. It is fully compatible with systems that originally carried a 7.7V label.
