Batteries with Higher CCA ratings also tend to be larger. They will still work in your car but may not fit in the battery tray. … Choosing a higher CCA battery can mean you have to replace it less often. It also means that your car will start reliably in colder temperatures.
Well, that’s still very important, because cold, cranking amps tells you the ability of the battery to do work right now. And the higher the cold cranking amp rating of the battery, the better it is for your car. … The cranking amps are rated at 32 degrees Fahrenheit.
Beside this, Is it bad to have too many CCA on a battery?
No you cannot have too much battery power. But you really only need to by the CCA that your car came with. Batteries that are the same size but have more CCA have weaker plates as they do various things to the plates to get more surface area and most of that makes the plates weaker.
Likewise, What is a good CCA rating for car battery?
Typical CCA readings for a car range from 350 to 600A, and higher for trucks. SAE J537 specifies that a battery with a CCA reading of 500A can deliver 500A at –18°C (0°F) for 30 seconds without dropping below 7.2 volts.
Also, How many cold cranking amps do I need?
What Size Battery Do I Really Need? A battery should be big enough to allow reliable cold starting. The standard recommendation is a battery with at least one Cold Cranking Amp (CCA) for every cubic inch of engine displacement (two for diesels).
Will high cranking amps hurt my car?
Having more potential current available will not hurt the car’s electrical system. It may actually provide for slightly faster starts, with less wear on the starter motor, but in most cases the difference is not significant enough to worry about.

Do higher CCA batteries last longer?
The battery with the highest CCA rating will last the longest. What’s inside the battery makes a difference, not just what the rating says on the label. Some types of batteries may be designed to provide maximum power, but neglect to take long-term wear into consideration.
How many cold cranking amps do I need for a v8?
A rule of thumb says a vehicle’s battery should have a CCA rating equal to or greater than engine displacement in cubic inches. A battery with a 280 CCA rating would be more than adequate for a 135 cubic inch four-cylinder engine but not big enough for a 350 cubic inch V8.
Can battery CCA be too high?
As long as it physically fits in the battery tray and hold-down, there will be no problem. Your new battery simply has more cranking capacity than your original. A good thing on cold mornings! as long as you didnt pay too much, no prob.
Does CCA matter on a battery?
Generally speaking, it is easier to start an engine in a warm environment than in a cold one. The rating refers to the number of amps a 12-volt battery can deliver at 0°F for 30 seconds while maintaining a voltage of at least 7.2 volts. The higher the CCA rating, the greater the starting power of the battery.
Is it better to have more cold cranking amps?
Well, that’s still very important, because cold, cranking amps tells you the ability of the battery to do work right now. And the higher the cold cranking amp rating of the battery, the better it is for your car. … The cranking amps are rated at 32 degrees Fahrenheit.
How many CCA should a battery have?
Still, it’s good to be aware of your CCA rating, as replacement batteries should equal or exceed the original battery in ratings to avoid poor performance. Typical CCA readings for a car range from 350 to 600A, and higher for trucks.
Can you use a higher CCA battery?
You can, usually batteries are bigger for higher CCA if the same technology is used on both. You’ll have to verify if the battery will fit in the battery bay. Getting the bigger battery may take longer, but will also last longer. Batteries with Higher CCA ratings also tend to be larger.

How many cranking amps do I need for a v8?
A rule of thumb says a vehicle’s battery should have a CCA rating equal to or greater than engine displacement in cubic inches. A battery with a 280 CCA rating would be more than adequate for a 135 cubic inch four-cylinder engine but not big enough for a 350 cubic inch V8.
Is 600 cold cranking amps enough?
A good CCA rating for a battery is between 400 and 500 cold cranking amps. This amount of power will be sufficient to boost small and large consumer vehicles even during harsh winter conditions.
How many cold cranking amps do I need for cold weather?
A: On average, a battery with 650 CCA is good for the cold climate. An 800 cold cranking amps battery ensures you’ll start your car in any weather.
At what CCA should a car battery be replaced?
There is no hard and fast rule though as to exactly when it should be replaced. I’d wait for 50% unless you live in a very cold area… CCA ( cold cranking amps) is rated to start a cold stiff engine in freezing conditions… You barely need 1/4 of that amp rating to start your engine on a normal day…
