Let’s try to find the battery capacity needed to run a pair of 55 watt halogen headlights for a total of 110 watts in 4 hours. Note that we’re using a 12 volt car ...Feb 20, 2023 · There is no way to convert CCA to Ah directly because there is no correlation between them. But for a rule of thumb, you can divide the CCA by 7.25 to get the calculated Ah. For instance, if your battery is marked with a 1450 CCA, it represents 200 Ah. A battery of this rating should last for 25 hours while producing power of 8 amps.The amount of power drawn from the battery in one hour is called watt hours and is the product of the two. For example, an AGM battery with 60Ah and 12 volts will have the capacity to produce 720watt-hours (60Ahx12v=720watt-hours). On the other hand, a 60Ah 6 volts battery will have the capacity to produce 360 watt-hours (60Ahx6v=360watt-hours)For example, a battery rated at 100amps multiplied by 7.25 is 725 CCA, cold cranking amp. Cold-cranking amps can be measured by the amps hours you can get from your car batteries based on their cold-cranking amps. You cannot calculate the amp-hours of a battery using a CCA calculator. Amount of Amps per hourExample 1: Must calculate the watt-hour capacity of a car battery having a voltage of 12 volts and capacity of 60Ah. View example.
