Accessibility
A reference platform is only useful if it can be read. World Battery Hub aims to keep its content usable by people with a wide range of abilities and with the assistive technology they use.
1. Our approach
- Semantic structure. Pages use headings in order, landmarks, lists and tables with header cells, so screen readers and keyboard navigation can move through a page logically.
- Keyboard access. Navigation, links, form-free interactions and our calculators are operable without a mouse where they are interactive.
- Text alternatives. Meaningful graphics and diagrams carry text alternatives; purely decorative elements are marked so assistive technology can skip them.
- Readable presentation. Content is written in plain language with expandable definitions in the glossary, and pages are built to remain usable when text is enlarged or the layout reflows to a narrow screen.
- Colour. Information is not conveyed by colour alone, and we aim for contrast between text and background that meets the AA threshold.
- No motion traps. We do not use autoplaying media, and we do not rely on animation to convey information.
2. Known limitations
- Dense data tables. Some specification and comparison tables are wide and information-dense. On small screens they may require horizontal scrolling; if a particular table is hard to use with your setup, tell us the page and we will look at an alternative presentation.
- Calculator tools. Our calculators are designed to be keyboard-operable and to announce their results, but their usability with every assistive-technology combination has not been exhaustively tested. Feedback here is especially useful.
- Third-party content. External sites we link to are outside our control and may not meet the same standard.
- Older pages. Pages written before this statement may not yet fully meet it; they are brought into line as they are reviewed.
3. Report an accessibility barrier
Email [email protected] and include:
- the page address (URL);
- what you were trying to do;
- what happened instead — including any error, or the assistive technology, browser and device you were using;
- your preferred way to receive a reply (for example, a description by email rather than a link).
We treat accessibility reports as editorial issues: we aim to acknowledge them and to fix or work around a barrier as part of our normal review cycle. If we cannot fix it quickly, we will tell you what we can do in the meantime — for example by providing the information in another form.
4. Standards reference
We use the Web Content Accessibility Guidelines (WCAG) 2.1, Level AA as our working target. This page is a statement of intent and practice, not a certification, and it does not claim conformance for every page at every moment.
