The main purpose of a car battery is to feed the electric current to the starter, which starts the engine. The lifetime of a car battery is 4 to 6 years. It does not mean that you have to wait until that time to replace your battery. You can test your battery regularly to make sure whether it is working fine or require replacements. Testing your car battery is an important part of routine maintenance.
Before testing your battery, you should know the battery ratings and specifications, which will help you understand the test results.
Battery Ratings and Specifications
Cold Cranking Amps (CCA)
The cold cranking amp rating is the most important rating on your car battery. The CCA rating is between 500 and 1000, which is the number of amps that the battery is designed to deliver at zero degrees Fahrenheit.
The cranking amp rating is measured at or above 32 degrees Fahrenheit. You can use this rating to get an idea about the condition of your battery. Generally, the cranking amp rating is 20% higher than the cold cranking amp rating.
A car battery’s reserve capacity is listed in minutes, which is the time your battery can discharge 25 amps before it drops below an unusable voltage. This number is significant if you use your car battery to power things when the engine is not running like a battery in a work truck or RV battery.
The frame size, otherwise the group number indicates the physical size of the battery and orientation of the “-“and “+” terminals. The frame size will help you know whether the battery fits your car.
