How Many Cold Cranking Amps Does My Car Need
In this article, we'll discuss, what cold cranking amps are, what cold cranking amps chart represents, the difference between CCA and CA, low CCA battery symptoms. Lastly, I'll briefly explain what is good CCA rating for car battery.
One question that most of the people, living in a cold climate, need to search for at some point in their lives, which is, what exactly is CCA?
One can simply define Cold cranking amps, abbreviated as CCA, as a rating that defines the ability of a car battery to start the car engine in frozen climates. As a general rule of measurement, we consider how many amps a 12-volt battery is capable of delivering for 30 seconds when the temperature is 00F with the battery maintaining the voltage to above 7.2.
Technicians also use another term known as cranking amp. Cranking amps represent the number of amperes a battery is capable of delivering for 30 seconds at 320F with each cell maintaining at least 1.2 volts.
Cold cranking amps chart
This CCA chart depicts the relation between battery capacity and CCA. The data is represented separately for high performance maintenance-free, maintenance-free, YuMicron, and conventional batteries. The graph clearly depicts that the higher the capacity of the battery higher will be the number of CCA.
Cold cranking amps vs Cranking amps
You would've normally seen automotive technicians using either of the CCA or CA, ratings to refer to the amount of power a battery can provide to your battery in starting the engine.
But have you ever thought what the difference between these two ratings is, as they normally sound similar? Well, the answer is pretty simple!
The difference between cold cranking amps and cranking amps is of temperature at which these ratings are based on. Where the CCA are measured at -18°C, the CA are measured at 0°C.
How many cold cranking amps do I need?
The number of CCA depends on which vehicle you are driving. If you are driving a consumer vehicle, 400 to 600 amps would be enough to start it. This value is 1500-2000 for commercials while only 150 for very small vehicles.
However, do remember this value varies with vehicle age, temperature, and the condition of the battery. Too high temperature, outdated vehicle, and having near-to-dead batteries increases the required number of cold crank amps. Thus, you'll have to measure them regularly to avoid the unexpected problem.
What is a good CCA rating for car battery?
For a normal consumer vehicle, more than 400 CCA are enough to start a car. However, the more cranking amps the battery has, the more smoothly it'll start and the battery would also last long.
Low CCA Battery Symptoms
4 symptoms that gives indication of low CCA are as follow:
- The engine cranks but doesn't start.
- The headlights of your car are dimmer than usual.
- The car starts on a warm day and causes trouble when the temperature is too low.
- You hear an abnormal sound when the car engine starts
Car battery CCA too low?
If you have recently changed your battery and found out that your car battery CCA is too. Then it's time to take replace the battery with a new one. If the CCA isn't low, there might be some other reason why your car engine isn't starting properly. One can get the testing done on your own using a digital multimeter.
At what percentage of CCA should a vehicle batteries be replaced?
Batteries are designed to provide more cranking amps than what is required for a given application. It compensates for the CCA decline during battery usage for a certain time period. When you should replace the vehicle battery according to its CCA? Well, it'll depend on which type of vehicle you are running.
So, what you need to do is to check the minimum number of cranking amps required to start your vehicle. Then check how much amps your battery is providing. If the value is more than what is required then you are good to go. But, if the required amps are more than what the battery is providing then it's time to replace the battery.
Still, as mentioned earlier, few other factors including vehicle age, battery performance and cold temperature also play a vital role in increasing the required number of CCA.
FAQs:
Cold cranking amps to start diesel engine?
If your diesel engine works on two batteries, then it must have more than 800 cold-cranking amps. This requirement is above 1000 Cold-cranking amps when only one battery is powering your diesel engine. These values may change depending on your weather but normally, having 1000 cold-cranking amps would be enough to start the diesel engine.
How many cold cranking amps do i need for a v8?
When we compare the power requirement of a four-cylinder engine with V8 engines, we clearly v8 requires more power. Hence, a battery installed with v8 must have higher Cold-cranking amps to run the engine smoothly in cold weather. According to the specifications of OE, v8 installed in a consumer vehicle must have a CCA value of at least 400 to 500. Still, bear in mind that a lot of other factors come into play including the car age, battery condition, and weather.
How many cold cranking amps do i need for my boat?
The cold-cranking amps requirement depends on the type of engine your boat is using and how old it is. Let's say, you have a 4-stroke Yamaha engine then you will need a starting battery with a CCA rating of 520 to 680 amps. The higher the amp and CCA ratings, the better your boat will perform.
Does, cold cranking amps matter?
If you are living in a cold-weather then measuring the cold-cranking amps once a month is very essential. They play a vital role in starting your car engine and your car battery must be capable of providing enough cold-cranking amps to start your car. If you don't pay attention and your battery couldn't provide the required CCA, expect to have a rough day on a snowy morning.
Final Thoughts!
In this article, I've tried to explain each and everything that you need to know about CCAs. I again emphasize to check your battery CCA ratings before buying it. Moreover, do regularly inspect it when it's about to cross its warranty period. This would save you from facing an unexpected problem in starting your vehicle engine on a freezing morning. Nobody likes that of course!
