A: You can confirm compatibility through three simple steps:

1. Check the Model/Part Number: Find your original battery's part number or your Surface model name and match it against our "Compatibility List" above.
   Tips: You can find these details in our Identification Guide.
2. Visual Match: Compare your original battery with our high-resolution product photos, paying close attention to the connector interface and shape.
3. Voltage Check: Ensure the voltage of the new battery matches your original one.

Note: If you are still unsure, please contact our support team or leave your model name in the order notes. We will perform a final compatibility check before the package leaves our warehouse.

A: Yes. Battery swelling (bulging) is a known issue for aging Surface devices due to thermal stress. Our replacement battery is built with upgraded thermal-resistant Grade A cells and a premium control chip. It prevents localized overheating, effectively eliminating the risk of swelling while restoring your screen to its perfect, flush position.

A: This is standard for newly installed batteries as the Surface EC (Embedded Controller) needs to recalibrate. For the first 3 cycles, charge the battery to 100% and keep charging for 2 more hours, then use it until it drops to 5%. This "trains" your Surface to recognize the exact capacity of the new cells.

A: We are a specialized parts supplier. Currently, we do not provide in-house installation services due to the high logistical costs and time required for two-way shipping.
Since Surface devices often require specific tools for disassembly (such as heating the adhesive), we recommend replacing the Surface BOOK2 KEYBOARD battery yourself if you are tech-savvy, or seeking assistance from a local repair professional. If you have questions during the installation, our support team is happy to provide technical guidance.

A: Yes, for most items. We stock and ship our inventory directly from our domestic US warehouses to ensure the fastest possible local delivery.

• Standard Shipping: Usually takes 3–7 business days to arrive at your doorstep.
• Tracking: A trackable USPS/FedEx shipping number will be emailed to you as soon as your order is dispatched.

Note: In the rare event of a temporary local stock shortage, our team will proactively contact you to confirm the shipping timeline before your order is processed.

A: To ensure you receive the correct battery and the best service, please follow these tips:

1. Verify Your Model: In the "Add a message to seller" box at checkout, please double-check and leave your Surface model or battery part number (e.g., Surface BOOK2 KEYBOARD). Our team will manually verify compatibility before shipping.
2. Shipping Address: Please ensure your delivery address is 100% accurate. If you are paying via PayPal, ensure your PayPal-associated address matches your intended destination to avoid processing delays.
3. Contact Email: Use a frequently checked email address for your order. This is how we send tracking numbers and order confirmations.
