Understanding Car Battery Ratings: What You Need To Know Before Buying

Car batteries are essential for the proper functioning of your vehicle, providing power to start the engine and operate electrical systems. When it’s time to replace your car battery, it’s important to understand the various ratings and specifications to ensure you choose the right one for your vehicle. Here’s what you need to know before buying a battery from a car battery supplier in Dubai.

Cold-cranking amps (CCA):

Cold-cranking amps (CCA) are a measure of a battery’s ability to start an engine in cold temperatures. The CCA rating indicates the number of amps a 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 more power the battery can deliver in cold temperatures.

Reserve capacity (RC):

Reserve capacity (RC) is the amount of time a battery can supply power to electrical systems in the event of a charging system failure. The RC rating indicates the number of minutes a battery can deliver a constant current of 25 amps at 80°F while maintaining a voltage of at least 10.5 volts. The higher the RC rating, the longer the battery can operate without being recharged.

Amp-hours (AH):

Amp-hours (AH) is a measure of a battery’s capacity, indicating the amount of time a battery can deliver a specified current before becoming fully discharged. The AH rating indicates the number of amps a battery can deliver over 20 hours while maintaining a voltage of at least 10.5 volts. The higher the AH rating, the more energy the battery can store and deliver.

Battery group size:

Battery group size refers to the physical dimensions of the battery and the location of the positive and negative terminals. The group size is specified by the battery manufacturer and is based on the make and model of your vehicle. It’s important to choose a battery with the correct group size to ensure it fits properly and is compatible with your vehicle.

Maintenance-free vs. flooded batteries:

Maintenance-free batteries, also known as sealed batteries, do not require regular maintenance and are designed to be maintenance-free throughout their life. Flooded batteries, on the other hand, require regular maintenance, such as adding water to the cells, to ensure proper performance and longevity.
