Lights and voltage labels reveal less than runtime and pack health.
The useful question
Lights and voltage labels reveal less than runtime and pack health. The real decision is how the issue changes compatibility, total cost, repair risk or safe use.
Build evidence
Save model data, photographs, seller statements, manuals, part numbers and completed-sale research. Separate what is known from what is assumed.
Use eBay deliberately
Search exact models and parts, compare new and used condition, inspect shipping and return terms and avoid treating one optimistic listing as market value.
Compare exact model numbers, included batteries or attachments, operating condition, photographs, shipping cost, seller history and return terms.
