A fit label requires an exact part, exact model, and a traceable source.
Verified fit
The manufacturer lists the exact model for the exact OEM part number. The reader still checks the machine label and current product page.
Check before buying
The source gives a condition, such as a pack number or voltage. We do not turn an unresolved condition into a confirmed recommendation.
Does not fit
The manufacturer explicitly excludes a model or documents a conflicting specification.
Compatibility not verified
The relationship has no adequate primary evidence in our catalog. This is not a claim that the part cannot fit.
Battery rule
We require exact pack and machine labels, voltage, and generation details where relevant. A shared series name is never enough.
