What is CCA (Cold Cranking Amps)?
CCA measures how much current a car battery or jump starter can deliver for 30 seconds at -18°C while maintaining a minimum voltage, indicating its ability to start an engine in cold weather. A higher CCA rating generally means more reliable cold-weather starting power, so jump starters and replacement batteries are commonly compared using this figure.
What Does pH-Neutral Mean for Car Shampoo?
A pH-neutral car shampoo is formulated to clean without stripping wax, sealant or ceramic coating protection from the paintwork, unlike household detergents or older-style alkaline car shampoos. This makes it the safer everyday choice for maintaining any existing paint protection, while stronger, non-neutral cleaners are generally reserved for occasional deep-cleaning or paint prep before reapplying protection.
