Are you going to buy a new battery for your car?
Car batteries have many different specifications that you need to be aware of. Modern cars use many electronic components and you need to get the right battery for your car.
In this article, we will help you find the information you need to find the right car battery for your needs and how you can convert CCA to Ah / ampere-hours.
There is no correlation between CCA and Ah. Therefore, you cannot convert it directly to get the exact value.
However, you can get an empirical value for most batteries, even if it is not an exact value, depending on the battery.
The basic rule for converting CCA to Ah is to divide the CCA by 7.25. For example, if your battery is marked with a 1450 CCA, that represents 200 Ah.
A battery in this category should last 25 hours while producing 8 amps of power.
Understanding your usage rate and voltage level will help you make the right battery choices, even if you only have the CCA numbers. Conversely, if you have the Ah ratings on your battery, you can calculate the CCA measurement to determine how well your battery is suited for starting your engine in cold weather.
What are Ampere-Hours (Ah)?
The ampere measures the flow of electrons and current in a conductor. A single ampere represents a single coulomb of electrical charge, which passes through every part of the conducting element in one second.
Battery measurements are usually written in units of ampere hours (Ah) and milliampere hours (mAh), which represents 1/1000. This unit represents the battery’s operating threshold, which can be used to calculate the battery’s lifespan without being recharged.
What are Cold Cranking Amps?
Many batteries use CCA to present the battery’s ability to start an engine at certain temperatures, typically between 30 and 32 degrees Fahrenheit. While knowing this starting power can help you choose a better battery, you will need to convert CCA to AH to determine the capacity.
CCA can be a good unit of measurement to help you determine the best battery for you if you live in cold conditions. Batteries with higher capacity and power will have better CCA values than weaker ones. Even if the battery’s power deteriorates over time, it will be more likely to last longer and provide better service.
