IвЂ™m going to cover how many amp-hours a car battery is estimated to have based on its Cold Cranking Amps, why car batteries are rated in Cold Cranking Amps and not amp-hours, and how many amps it takes to charge a battery up.ДЇeel free to open this in a new tab to access my easy to use calculators to figure out how long it will take you to charge any car battery with any charger. Still, that didnвЂ™t stop me from doing some research to see if we could get a relatively comfortable ballpark estimate of a car batteryвЂ™s relationship between the two. Maybe you can draw a few correlations but correlations do not mean causation. It would be like trying to compare the efficiency of one car by seeing how one can go from zero to 60mph with another car by using average miles per gallon. There is no hard-and-fast rule for converting amp hours to cranking amps or cold cranking amps (or vice versa). Typically, car batteries are rated in CA or CCA (Cranking Amps, or Cold Cranking Amps) and not in AH (Amp Hours) like a deep cycle battery for powering appliances or electronics. Larger vehicles, such as trucks, can have batteries around 75 amp-hours. Mid-sized batteries for larger cars and SUVs are around 50 amp-hours. Small car batteries are around 40 amp-hours. If youвЂ™re in a pinch and donвЂ™t have a marine or deep-cycle battery around, you might find yourself wondering just how many amps (amp hours) a car battery has to power something. It has a lot of energy but it is best at delivering that energy in small but high amperage bursts. That 40-pound car battery under your hood is generally rated in cold cranking amps - not amp-hours.
