Introduction to Cold Cranking Current

Cold Cranking Current (CCA) is a rating that defines the ability of a battery to start or crank an engine at low temperatures. We usually see CCA (Cold Cranking Current) or MCA (Marine Starting Current) etc. on batteries, CCA’s usually range from 100 to 1000 or higher, depending on the vehicle, and for people who use their vehicles or boats in cold areas, they need the Cold Cranking Current to be high enough to start the vehicle or boat.

The CCA rating best describes the amount of amperage it takes to make sure that won’t interfere with starting the engine in cold weather, letting you know specifically how many amps the battery will support for 30 seconds while maintaining at least 7.2 volts in temperatures from -18°C to 0°C.

The Importance of Cold Start Current

For those who live in cold areas, cold start current is indeed important, due to the cold weather, it will reduce the performance of the battery, and the life of the battery will shrink, when we use the vehicle we will find that the vehicle cannot be started, this may be caused by the lack of cold start current or damage to the battery itself and the related wiring, after checking on the battery, that is the cold start current is too low to start the engine, so you need to choose a slightly higher cold start battery to avoid too high and dangerous accidents.

Even if we live in a warm area, we will encounter insufficient cold start current, we’d better choose a starting battery that meets the automotive standard to avoid battery damage or not being able to start the vehicle.
