What does CCA / Cold Cranking Amps mean ?

Cold Cranking Amps determine how much power you have to start your car in most climates. The ‘cold’ refers to when the vehicle engine is started from cold – e.g. first thing in the morning or after a period of rest in cold environmental conditions (the engine has cooled to below 5 degrees celsius). A cold engine, as opposed to one that has just been running at optimum temperature, will take more energy to start and thus needs plenty of CCA!
