Lookup

What it is

Lookup is the public side of a passport. The address /p/ followed by the battery's id shows the fields its owner has published.

The public page names the fields it is withholding instead of leaving them silently blank. Condition data, such as state of health, opens only after the reader declares why they need it, and each request is recorded.

A reader can save the page as a PDF from their browser.

Who it is for

• Buyers of used batteries.
• Recyclers sorting packs on arrival.
• Regulators and inspectors checking a record.

How it works

1. Scan or type. Scan the QR on the label, or enter the battery id on the lookup page.
2. Read the passport. The published fields appear. A battery that is not published is never shown: it answers not found.
3. Declare a purpose for condition data. Choose purchasing, recycling, inspecting or owner to see state of health and cycle count. Readings behind it are stored with their source.

What it does not do yet

• The declared purpose is asserted, not verified. It is a record, not a login.
• Condition data requests are rate limited. The published passport is not.
• Condition figures come from the battery's own management system, not an independent estimate.
