Cold cranking amps cca.
Car battery specs cca.
Before you start researching other characteristics like the cold cranking amp cca rating and terminal position it s good to start by consulting a battery size chart.
Replacing a battery with a battery that has a lower cca than the original equipment may result in poor performance.
The discharge load in amperes that a new fully charged battery can deliver at 0 degrees f for 30 seconds while maintaining a voltage of 1 20 volts cell or higher.
If your battery is 4 years old or older your car or truck battery is at risk.
It is more difficult for a battery to deliver power when it is cold out so the cca rating is the best one to go by.
3 4 out of 5 stars 31 ratings based on 31 reviews current price 98 76 98.
It is the estimated amperage that the engine requires when the car battery is subjected to the most severe strain such as starting in an extremely cold condition.
For cold cranking amps cca the standards.
Replacement batteries should equal or exceed the oe battery in ratings.
For an automobile battery with six cells each capable of generating 2 volts for a total of a 12 volts the measurement of cranking amps ca represents the number of amps the battery can produce for 30 seconds at 32 degrees fahrenheit while generating 1 2 volts per cell or 7 2 volts for the battery.
The rating for the cca is crucial.
The higher the number the better.
Cold cranking amps are the number of amperes a lead acid battery at 0 degrees f 17 8 degrees c can deliver for 30 seconds and maintain at least 1 2 volts per cell 7 2 volts for a 12 volt battery.
Your new battery s cca number should match the cca number in your owner s manual or the cca of the vehicle s original battery.
Battery starting power deteriorates as the battery ages so a battery with higher starting power should give you more confidence over time.
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.
If you use a battery with a lower cca rating than that.
Product title everstart maxx lead acid automotive battery group size 35n 12 volt 640 cca average rating.
We ll even take care of the old one with battery recycling.
It s based on how well a new battery will supply sufficient power for 30 seconds at zero degrees fahrenheit.
Cca is a very important battery performance indicator.
When it s time for a replacement we ve got the right battery to get you back on the road.
If you re worried autozone offers free battery testing and charging service to check out your current battery.
The new battery s cca should be the same if not higher than that of the original battery.
