When it comes to batteries, CCA is a rating that is used to determine a battery’s ability to start an engine in freezing weather. There is a certain CCA value you need to start your car.
You may have asked yourself; can I use a battery with higher cranking amps? Will it hurt my car? Do I need to change my battery to fix the problem?
In short, yes. But you need to consider temperature, battery size and overall health of your car. Confused? Don’t worry.
In this article I have completed the research for you! Read entirely to find out what happens when you have a battery with higher cranking amps.
Why Do Cranking Amps Matter?
The bigger the CCA rating of the battery, the better the starting power of the battery.
In general, starting an engine in a warm atmosphere is less difficult than starting one in a cold climate.
It is the number of amps that a 12-volt battery can deliver at 0°F for 30 seconds. All the while maintaining a voltage of at least 7.2 volts that is specified in the rating.
Can You Use a Battery with Higher Cranking Amps?
To function properly, a car battery must only meet the minimal CCA requirements. This means that if the CCA of the original battery has been reached or exceeded, there is no need to be concerned.
A greater CCA is alright as long as the battery fits, the terminals are on the correct side, and the battery has at least the minimum CCA required by the vehicle’s manufacturer.
However, a Cold Cranking Amps rating of too high a value can lead to issues like as undercharging and overcharging and some other issues.
While larger cranking amps can make cold-weather starts easier, this does not always imply that the battery will live longer or perform better.
A battery with a higher CCA rating may be too powerful for your starter. It can cause the engine to crank slowly or not at all, as well as harm valuable electrical components in your vehicle.
There’s still a chance that if you use a lower-quality battery with less cranking power on an older car with worn-out starting components, the starter won’t be able to turn the engine over.
The higher your CCA, the faster a battery can supply adequate current to start the engine. A battery with a higher CCA rating is often more expensive.
The biggest disadvantage of utilizing a higher CCA is that these batteries need an extra discharge cycle or two to reach full capacity, so anticipate to have less power available at first.
But it is suggested for those who drive in cold weather because it operates better at lower temperatures.
Is a Higher CCA Battery Better?
It’s common to think that a battery with a higher CCA rating is better for your car. This is only partially true.
In colder regions, more CCA will help the car crank start. It implies that in colder weather, your automobile will start dependably.
But in the heat of the summer, a higher CCA battery can leak and, in some cases, fail. When selecting a car battery, keep in mind that this is a possibility.
Batteries with higher CCA ratings are typically larger as well. They’ll work nicely in your car. However, they might not fit in the battery tray. It also increases the weight of the car.
Another thing to consider is the alternator. It charges a battery intended for a specific Ah rating (for example, a 35Ah battery will have an alternator designed to fully charge it in 2 or 3 hours of driving).
If you install a larger Ah battery, the alternator will have to run for longer to fully charge it. This will put a strain on your alternator, making it easier and less expensive to replace the battery rather than the alternator.
Can a Battery Be Too Powerful for a Car?
In simple words, no. It’s not so much about the battery being “too powerful” as it is about it not being able to produce enough power at any one time or under unusual conditions.
Several protections are in place to prevent the batteries from supplying excessive power. These are: preventing overcharging, recognizing when cells are becoming unstable, and detecting shorts or leakage before they occur.
Can a Bigger Battery Hurt My Car?
Because most vehicles have limited space for batteries, a greater size may not be practical in many circumstances.
In most cases, the terminals will come into touch with the hood and short out the battery, or the physical dimensions will simply not work. The physical size of a battery does not indicate its power or lifetime.
Do a Higher CCA Battery Last Longer?
Batteries today are smaller and have a higher CCA capacity/rating than the original batteries in cars. Batteries having a substantially higher CCA rating appear to survive significantly longer, particularly when used in cold weather.
But the longevity of the battery also depends on other factors such as amp-hours. The Amp Hour (Ah) rating of a battery indicates the amount of power it has and how long it will last.
In simple terms, this indicates how long a battery will last if it is not recharged after being used.
When Should I Replace the Car Battery According to Its CCA Value?
Your battery’s CCA value must remain above the OE or OEM CCA guideline. If the CCA value of your battery is less than the required standard, the battery may need to be replaced. A battery should be replaced when it produces less than half of its CCA rating.
The temperature of the surrounding air when the battery is being tested must also be taken into account. The CCA number should be closer to the original rating if the temperature is above freezing when the battery is tested.
However, even in warmer temperatures, if the CCA value is significantly lower, it is time to replace the battery. The frequency at which you should replace it is determined by your vehicle’s CCA requirements.
Overall, a battery with a greater CCA might be more dependable and last longer. Charge loss and other factors cause CCA to drop with time.
If you’re trying to jump-start a dead or discharged battery, higher Crank Amps are better because they provide more starting power.
However, for a regular working battery, staying within the 350A to 600A range is ideal. I hope this answers your question “Can I use a battery with higher cranking amps?”
