About World Battery Hub

World Battery Hub is a battery knowledge and data platform. It is informational, not a store.

Editorial method

• Cross-verified, not translated — content is synthesized from multiple independent sources, including Chinese and English, not translated from a single source.
• Every number carries its standard — a CCA value states whether it is JIS, EN, SAE or DIN; a capacity states its rate (C20, etc.).
• Conflicts are explained — where sources disagree, the disagreement and its likely cause are stated rather than a single number being silently chosen.
• No fabrication — if a figure cannot be traced to a source, it is stated qualitatively or marked as unknown.

Source hierarchy

Primary sources (manufacturer documentation, standards organizations, government data) are preferred over industry publications, which are preferred over community sources. Community sources are used to discover real-world questions, not as evidence.
