How to find your model, part number, or battery code
The fastest way to buy the correct item is to match what you already have. Use the steps below before ordering.
⚡ Before you start
→Take a clear photo of the label (battery or adapter) under good light.
→Use the wrong part prevention checklist to avoid common mistakes.
→Copy the part number and voltage exactly — including dashes and decimals.
→If you have multiple similar parts, label your photos so you don't mix them up.
🔋
Laptop batteries
1
Turn off the laptop. If the battery is removable, remove it and read the label.
2
Note the battery part number / battery code — examples: "A32‑K55", "GK5KY", "HS04".
3
Match voltage (V) first. Then compare capacity (mAh / Wh). Voltage must match exactly.
4
If the battery is internal, check the laptop underside label for the model or service tag, then confirm the battery code when opened.
🔌
Laptop adapters (chargers)
1
Read the adapter label under OUTPUT — example: 19.5V ⎓ 3.33A.
2
Note the wattage (W) if printed, or calculate it yourself: W = V × A.
3
Match the connector type — USB‑C vs barrel tip, and tip size. Do not assume all round tips are the same.
4
If you have it, also match the adapter part number printed on the label.
📱
Phones & tablets
1
For batteries: match the battery code on the battery label — often starts with EB‑, BP‑, BN‑, etc.
2
For chargers: match the connector type (USB‑C / Lightning / Micro‑USB) and required wattage.

Frequently asked questions
Where can I find the laptop model number?
Check the underside sticker or the system info screen. For many brands, the exact model is printed near the serial number or service tag.
Is the battery code the same as laptop model?
No. Battery codes (like HS04, GK5KY, A32-K55) are printed on the battery label and identify the battery type, not the laptop name.
What if I cannot remove the internal battery?
Use the laptop model/service tag first. If possible, send a clear photo of the battery label after opening the bottom cover, or contact support for verification.
