BDifficulty 2/5

On a conventional 12 V starter battery, whether or not electrolyte maintenance is required, should the terminals be kept clean?

Correct answer

Yes, on both types of starter battery.

Yes. Dirt or corrosion and poor connections can impair contact and make starting difficult. Follow the manufacturer’s safety and tightening instructions; a maintenance-free electrolyte design does not mean connections may be neglected. Do not treat high-voltage systems as conventional starter batteries.
