Usage Tips
Ensure at least minimal clearance around the battery negative post before installation.
Tighten terminal connections securely but avoid over-torquing to protect threads.
Use in systems within the specified 12V/24V range and do not exceed 250A continuous load.
Care & Maintenance
Keep terminals clean and free of corrosion; apply a light dielectric grease if used in marine or high-humidity environments.
Inspect connections periodically for tightness and wear.
Store in a dry place when not installed.
