What You Need to Know About Car Batteries

A car battery provides power to run a vehicle’s electrical accessories and, of course, start the engine. It’s a complex yet essential piece of automotive equipment. The precise inner workings vary across car battery types, but the general principles are pretty straightforward. Car batteries contain lead plates and a solution of water and sulfuric acid that generate electricity by chemical reaction. This energy powers the many parts of your automobile’s electrical system, including your radio, GPS and wipers. It also starts your engine by sending voltage to the starter relay via a pair of contacts that close when you turn the ignition switch.

Modern batteries are also designed to last longer, and require less maintenance than those of 10 years ago. However, it’s a good idea to get your battery load-tested at a mechanic every two or three years, whether the battery is old or new. This will give you an accurate reading of its condition and help you know if it’s time to replace it.

The best Car battery for your needs will depend on the type of automobile you drive and where you live. For example, cold climates require more physical cranking power from a battery than warm ones. That’s why it’s a good idea to look at the battery’s Cold Cranking Amps CCA rating when shopping for one.

A battery’s CCA number can be found on the label, and is also listed in the car’s service manual or an online resource. The higher the CCA number, the more power the battery can deliver to your vehicle’s starter. The reserve capacity of a battery is also an important consideration. This figure tells you how long the battery can provide power to your vehicle after it’s been turned off.

Another important factor to consider is the battery’s group size, which determines how much space it takes under the hood. A larger case will take up more room than a smaller one. Some modern cars have multiple battery options for different performance levels, so it’s worth looking into the individual battery ratings.

Battery longevity can be affected by temperature and vibration, so it’s a good idea to keep the car in a cool location when possible. It’s also a good idea to run your engine regularly during hot weather to keep the battery well charged.

Finally, it’s a good idea to check on the battery and its terminals for signs of corrosion. This can appear as white dust on the terminals and cable clamps. If there is any corrosion, you can clean it with a toothbrush dipped in a mix of baking soda and water.

A battery is a significant investment, so it’s a good idea do some research to find the right one for your vehicle and budget. By using an easy-to-use car battery fitment tool like the one on our site, you can quickly narrow down your options and make a confident purchase.
