The Cold Cranking Amps, or CCA, of a battery lets the owner know how much of a surge capacity a battery might have. IOW: How much power can a battery provide over a short period of time. Amp Hours, or AH, of a battery lets the owner know how long the battery should be able to provide power at a certain rate.
You can turn Cold Cranking Amps (CCA) into Ah to be better able to find battery capacity. A large number of batteries use CCA to present the battery’s ability to start an engine at certain temperatures, usually ranging between 30-32 degrees Fahrenheit.
Now, get back to the cold cranking amps and amp hours. The quick and short answer on this question is that it depends. While there is no direct correlation between CCA (cold crank amps) and Ah (Amp Hour) some companies tend to give their exact formulas on how they get this relations.
cold cranking amps are related mainly to plate surface area amphours are related mainly to amount of material in the plates. So two batteries with the same amount of plate material, one with a lot of thin plates and the other with a few thick ones, could easily have the same amphour rating and wildly different cold cranking amps.
you cant. my car has a 45Amp hour battery. this means if i leave the door open the 1 amp the dome lights take will kill the battery in 45 hours. the 300 cranking amps 45amp hours /300amps =.15 ...
How to Convert Reserve Capacity to Amp Hours. The reserve capacity of a battery is the number of minutes for which it can run at 25 amps of current without its voltage dropping below 10.5 volts. It roughly describes the amount of energy the battery effectively stores and technically specifies the battery's charge ...
Cold Cranking Amps (CCA) Reserve Capacity & Amp Hour (C20) Battery Applications; Cold Cranking Amps (CCA) CCA is a rating used in the battery industry to define a battery's ability to start an engine in cold temperatures. Generally speaking, it is easier to start an engine in a warm environment than in a cold one.
The amp hour rating is cumulative, so in order to know how many constant amps the battery will output for 20 hours, you have to divide the amp hour rating by 20. Example: If a battery has an amp hour rating of 75, dividing by 20 = 3.75.
Answer 1 No difference, but cold cranking amps is what is in battery to start. Answer 2 Answer 1 is correct so far as amps are amps. However, the ambient temperature to which the battery is ...
Cold Cranking Amperes (CCA)/Marine Craking Amperes (MCA) CCA and MCA measure the power capacity of a battery. CCA is the discharge load in amps which a battery can sustain for 30 seconds at 0°F/–18°C without falling below 1.2 volts per cell (7.2V on 12V battery).
