## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are best for battery terminal posts in corrosive environments?
**A**: Nickel-plated steel offers excellent corrosion resistance, while copper alloy provides superior conductivity. For marine or industrial applications, nickel-plated options are recommended.

### Q: How do I determine the correct torque rating when installing battery terminal posts?
**A**: Always follow manufacturer specifications, typically 5-15 N·m for automotive applications. Overtightening can damage threads, while undertightening causes poor electrical contact and overheating.

### Q: What factors affect the current rating of battery terminal posts?
**A**: Current rating depends on material conductivity (copper alloy highest), cross-sectional area, and temperature range. Proper installation and corrosion protection maintain rated performance.
