Wrong part prevention checklist

Returns are expensive and slow. This checklist is the fastest way to avoid ordering the wrong item. If you only do one thing: match the label on the part you already have.

Step 1 — Take the right photos

Battery/adapter label photo: sharp, full label visible, no glare.
Device underside label: brand + exact model + service tag/serial (if present).
Adapter connector tip photo (adapters only): close-up of the plug, from the side and front.

If you’re not sure where to find these labels: How to find model/part numbers.

Step 2 — Batteries: what must match

Part number / battery code: match exactly (examples: GK5KY, HS04, A32‑K55).
Voltage (V): must match.
Capacity (mAh / Wh): can differ, but quality matters (avoid unknown/unsafe cells).

Step 3 — Adapters: what must match

Output voltage (V): must match (read the adapter label under OUTPUT).
Current (A): can be equal or higher (never lower).
Wattage (W): must meet the laptop requirement (W = V × A).
Connector type/size: USB‑C vs barrel tip, and the barrel OD/ID/center pin must match.

Common mistakes that cause wrong orders

Ordering by laptop model only (multiple revisions exist).
Matching “looks similar” barrel tips without measuring OD/ID.
Using an adapter with correct voltage but insufficient wattage.
Ignoring the battery code printed on the battery label.

FAQs

What is the #1 cause of ordering the wrong battery or adapter?

Guessing based on device name only. Many models ship with multiple battery/charger revisions. Matching the label on the old part (part number + voltage) is the safest method.

Is the connector size more important than wattage for adapters?

Both matter. Output voltage must match. Connector tip must match physically. Wattage (W) should meet or exceed the device requirement.

What should I send to support for the fastest compatibility confirmation?

A clear label photo (battery/adapter), your device model/service tag, and for adapters a close-up tip photo + measured connector size if possible.
