Things you need to know about car batteries:
How to Choose the Right One?
Choosing the right car battery is not an easy task. Here’re a few factors that you must consider while purchasing a new car battery:
Check the Owner’s Manual
Before buying the battery, check the Owner’s Manual of your car. It will have all the necessary information regarding the basic parts of the car. Check the dimensions of the battery, the CA, the CCA rating, and the ampere-hour rating. Buy the battery that corresponds with the exact specifications mentioned in the manual. Don’t settle for anything that does not meet the specified criteria. Even if you do, the battery will give up in a few days’ time.
Buy a battery with a moderate Ah Rating
The Amp Hour or AH of a battery defines the battery’s capacity. It is a measure of the amount of energy that can be stored in a car battery. You must never buy a battery with lower Ah rating as compared to your existing car battery. In case you end up buying a battery with the lower Ah rating, you will have to go through starting troubles. This will also affect battery life.
Also, you must refrain from buying a battery with higher Ah rating as it will cause slow charging, as well as the burden on the alternator.
Pick a battery with a higher CCA
Cold Crankings Amp or CCA of a battery is the rating used to define a car battery’s ability to start the engine in cold temperature. In other words, CCA refers to the number of amps a 12V battery can provide at zero-degree Fahrenheit for thirty seconds while preserving a voltage of at least 7.2 volts. If you live in an area where the temperature tends to drop, you must buy a battery with higher CCA. The higher the CCA of a car battery, the better will be the starting power of the battery.
Pay Attention to the Dimensions
Although most of the batteries come in standard dimensions, you must check if the battery fits accurately in your car. Also, make sure that you buy a battery with loops or handles, especially if you tend to maintain the car yourself.
Check the Manufacturing Date
A battery that has been bought within six months of manufacture is considered fresh and hence, you must confirm the manufacture date before buying the battery.
Keep the following things in mind regarding the manufacturing date of a car battery:
- When you pick a battery from the wide-range of batteries on the market, make sure you check the date of manufacturing which will be printed on the battery. If you’re unable to find the printed date, you can check a code that is an alternative for the date of manufacturing.
- A car battery bought within six months of manufacturing is considered as new.
- Make sure you store your Warranty Card carefully in case the car battery malfunctions in the specified warranty period to try for a replacement.
Did you know – batteries lose their strength and effectiveness when stored for a longer duration. For optimum performance, pick a battery that has been on the shelf with not more than 6 months.
