What This Hub Is For

This hub provides technical documentation to help engineers, fleet managers, distributors and buyers specify the right truck battery:

• Battery standards (JIS, DIN/EN, BCI, SAE J537)
• Cold Cranking Amps (CCA) and Reserve Capacity (RC) explained
• Selection guides and comparison tables
• Maintenance and troubleshooting
• Application scenarios (long-haul, cold-chain, mining, semi-trailer, generator)

Our Editorial Standards

1. Sourced specifications — all CCA, capacity and dimension values come from Chengguang Power Tech Co., Ltd. technical documentation under an IATF 16949 quality system.
2. No unverifiable claims — where a value depends on the vehicle, we say so and direct you to your manual.
3. Named authorship — content is written and reviewed by Martin Wong, Sales Director at Chengguang Power Tech Co., Ltd., with 14 years in battery manufacturing. We attribute to a real, named expert. We never fabricate an individual expert; Martin Wong is the actual person responsible for this documentation.
4. Transparent dates — every article carries publication and update dates.
