How to Find Acer Battery Part Number？

By HP-BATTERY Updated on 2025-10-23

In this guide, we'll show you various ways to find the battery part number for your Acer laptop, including through the manual, label, or official Acer tools.

Acer laptops are known for their extensive product line and diverse model range, but they can also present some challenges for users, especially when it comes time to replace or repair the battery. Replacing or repairing an Acer laptop battery can be challenging if you don't have the correct part number.

First, let's understand the naming convention for Acer battery identification codes: Acer battery identification codes typically consist of letters and numbers, such as "AP18D7J," "ap17c5p," and so on. The purpose of the identification code is to ensure that the battery is compatible with the laptop. Additionally, it's best to verify the battery's appearance, voltage, capacity, and image to ensure complete accuracy.

Below, we'll introduce four methods to help you accurately locate your laptop battery part number.

Method 1: Consult the original manual (the most direct source of information).

The user manual or repair guide that came with your laptop is the most authoritative source of information. The "Hardware Specifications" and "Battery Maintenance" sections of the manual typically clearly indicate:

• Supported battery models and part numbers;
• Battery physical specifications (capacity, size, connector type);
• Replacement precautions (such as power-off procedures and anti-static precautions).

Tip: If you've lost your manual, you can enter your model number in the "Support" section of Acer's official website to download an electronic version.

Method 2: Directly inspect the battery (the most intuitive physical identification).

• Remove the battery (some ultrathin laptops require disassembly; be sure to disconnect the power and discharge static electricity before handling). Check the following areas:
• Label area: The white/silver label on the bottom or side of the battery usually has "P/N:" (Part Number) or "Part Number:" followed by the full battery number.
• Model identification: If the label is worn, look for the "Model" or "Model:" field and record the battery model (e.g., "Acer 4820mAh") to later reverse-check the battery number on the official website.
• Identification code: A string of characters separate from the part number (e.g., "CN12345678") used for official compatibility verification.

Method 3: Official website/Acer official tool assisted query (the most convenient digital solution)

• ​​Official website support page​​: Visit Acer's official website, go to "Service and Support" → "Enter Product Information", enter the notebook serial number or model, the system will automatically jump to the "Hardware Details Page", where the "Battery" item will list the original part number;
• ​​Acer Care Center application​​: Download the official management tool from the Microsoft App Store or Mac App Store, open it and go to "Hardware Information" → "Battery", you can directly read the current battery model and compatible part number.

Method 4: Contact Acer's official customer service (the most reliable manual backup)

• If the above methods cannot confirm, you can call Acer's customer service hotline (1 (866) 695-2237) or consult through the official website online chat. What needs to be prepared in advance:
• Complete notebook model (check on the bottom of the body or in Settings → System → About);
• Serial number (SN code, usually affixed to the bottom of the body or inside the battery compartment);
• Current battery usage status (such as whether it is swollen or the battery life is abnormal). Customer service will provide the officially certified battery part number and purchase channel recommendations based on the model information.

Summary: The key to replacing an Acer laptop battery is "precise matching." By consulting the manual, inspecting the physical markings, using the official website's tools, or consulting with customer service, users can efficiently identify the correct part number and avoid performance issues or warranty disputes caused by mismatches.
