The power and longevity of a battery is noted by its Amp Hour (Ah) rating.
Cold cranking amps (current) is the amount of power that can be discharged and sustained for 30 seconds at a temperature at or below 0 degrees Fahrenheit or -18 degrees Celcius without dropping below 7.2 volts for a 12v battery.

It is a battery industry rating used to determine the ability of the battery to start or crank up an engine when the weather is cold.

A dual purpose/deep cycle battery does have an AH rating which should help you determine if it will suit your needs as a deep cycle battery.



In simple terms, the higher the CCA, the easier it will be to start the vehicle.
HCA, CA, or MCA numbers may look higher than the CCA number, but because these tests take place at 32 degrees and 80 degrees Fahrenheit, they are not equal to CCAs. Cranking amperages (CCA, CA, MCA, HCA) Cold cranking amperes (CCA): the amount of current a battery can provide at 0 °F (−18 °C). When a car battery has voltage but is not cranking amps, how many should a chart read and how to test for it—12.5 volts, perhaps? The cranking amps are rated at 32 degrees Fahrenheit. The higher the CCA, the better a battery can perform at start-up. Basically, this denotes how long a battery will last if it isn’t recharged. CCA is the current that a battery … If a battery is rated as 100Ah, it will produce 100 Amps for 1 hour. For example, with a flat starter battery, there is no reason why a deep cycle battery could not be used to crank the engine but any long term use will shorten the battery’s life. Cold Cranking Amps (Current) Explained. See, cold, cranking amps – CCA, cranking amps – CA. But, don’t get that confused with cranking amps – CA. For an automobile battery with six cells, each capable of generating 2 volts for a total of a 12 volts, the measurement of cranking amps (CA) represents the number of amps the battery can produce for 30 seconds at 32 degrees Fahrenheit while generating 1.2 volts per cell, or 7.2 volts for the battery.

On the other hand, Cold Cranking Amps (CCA) refers to the number of amps that a battery can push out for 30 seconds at 0° F without dropping under 7.2 Volts. Cold Cranking Performance (Amps) The Cold Cranking Performance (CCA) measures the starting performance of the battery. Note that some batteries use hot cranking amps (HCA), cranking amps (CA), or marine cranking amps (MCA) numbers.

Cold cranking amps (CCA) directly correlate with battery performance. ... – Susceptibility to cold weather and temperature, even at a standard 12.4-volts or 12.5-volts in a standard voltage reading. For example if a battery is rated as, say 8Ah, it will be able to provide 4 amps for 2 hours. h) is a unit related to the energy storage capacity of the battery. CCA stands for Cold Cranking Amps.

A dual purpose/deep cycle battery operates at a low amp level to run electrical components, but also has the cranking amps to start an engine. This rating is required by law in Europe. And the higher the cold cranking amp rating of the battery, the better it is for your car.

Specifically, it refers to the amps that can be delivered by a 12-volt battery for 30 seconds at 0°F or -18ºC and at the same time maintain a minimum voltage of 7.2 volts. SAE (J537 Jun 1994 American Standard) This is the starting test according to the SAE (Society of Automotive Engineers). Choose a battery based on CCAs instead. A. Remember that a jump starter is really another battery supplying power to your car’s battery.
