HOW TO CHOOSE A CAR BATTERY: 3 CRITICAL FACTORS
Every car owner has at least one thing in common with every other car owner: every few years, it may be time for a new car battery. Not all car batteries are created equal and different cars have different battery requirements, so its important to have your battery’s health checked frequently. If you would need a new battery, here are three key things you need to know about how to choose a car battery and make sure it’s installed right.
1. Know Your Alphabet
Do you know what CCAs are? The acronym stands for cold cranking amps, which represent the speed at which the battery can put out power in cold temperatures. That matters because engines are harder to start in the cold. It takes more work for the starter to get the engine cranking and the thicker, cold oil to flow through. A battery with an insufficient CCA rating can contribute to more wear and tear on the starter, longer start times, and even failure to start in cold weather. Picking a battery with sufficient CCAs is critical.
2. Connections Count
Making sure your vehicle’s battery cables have a tight, clean connection with the battery’s terminals is extremely important. Loose cable connections will not conduct maximum power and cause problems over time. Cable terminals and battery posts that are covered with corrosion will also inhibit power and will affect power, eventually leading up to a no-start situation. Make sure to clean terminals periodically. Terminal cleaner and protection sprays can help. Your connections are key to ensuring the battery is installed properly and can deliver the intended power it was meant to give.
3. One Size Doesn’t Fit All
Another key thing to know is that batteries come in many different sizes, though that may not be obvious at first glance. It’s because of the battery tray or battery box that secures your battery in your car — you don’t want that 30- to 50-pound battery coming loose on a sharp curve and doing damage. Different makes, models and years need different battery sizes, and the difference can be just a fraction of an inch. Even the same make, model and year can have more than one battery size if your vehicle is equipped with an optional engine. Make sure to follow the application guide closely so that you have the right battery for the right application, which will lead to long life and confident starting power.
Knowing how to choose a car battery is easy if you follow these steps. Remember, knowledge is power — in this case, battery power.
