How to Choose the Right Battery for your Car?

Posted in Services

The battery provides energy and electricity needed for your car to function properly. But each battery has a lifespan of about three years.

Before you go and buy a new car battery, you first need to know what size, brand, reserve capacity, age and cold-cranking amps you need.


The size of the car battery refers to the width, height, and length. You will find batteries in various sizes, but you need to make sure that the one you choose fits perfectly into your car’s battery tray. You should always check your car manufacturer’s manual to see the exact size of the battery.


The brand refers to the company which manufactured the battery. Your car’s user manual specifies the battery brand, but if it is too expensive for you and you want to do some cost-cutting you can read the specifications from the manual. Do not purchase the cheapest battery you find because it might be a poor performer and also be loaded with defects.

Reserve Capacity

The reserve capacity rating or RC is, in fact, the battery’s standing power or the number of minutes it can continuously offer minimum voltage to run the car in case the alternator or the fan belt fail. The RC rating is not specified on the battery’s label so you’d better check the product’s literature or ask the store assistant to find out which the RC rating for a certain car battery.

The RC rating is your vehicle’s emergency kit, as it will keep the car running and prevent you from getting stranded. It is not safe to buy a battery with the longest RC rating you find. You need to read the car’s manual which is the right capacity for your car.


A battery can be considered new if it is less than six months old. Check the manufacturing date on the label or the battery case. The first letter is the month (A= January, B =February, etc.) and the digit is the year (9 = 1999, 0 = 2000, 1 = 2001, etc.).

Cold-Cranking Amps

The cold-cranking amps or CCA measure the ability of the battery to start the vehicle even in an extremely cold weather. CCA also refers to the number of amps the battery can support for 30 seconds at freezing temperatures. Better choose a battery with a high number of cold-cranking amps, especially if you live in a cold climate.

The purpose of cranking or shallow cycle type is to release a rapid surge of energy to get your car started in cold weather.

Difference between CCA and CA

The CCA or cold cranking amps indicate how much power the vehicle battery can give to the engine at a frozen point.

The CA or cranking amps measures the electricity in the battery at a frozen point. The CA rating should be higher than the CCA rating.

Do not choose a car battery which has a CCA rating much higher or much lower than the one recommended by the car’s manufacturer.
