Knowledge is power when it comes to your car’s battery and electrical system. In fact, it’s your ride’s heart and soul. The last thing you want is to be left stranded with a dead battery. The more you know about your battery and electrical system, the less likely you’ll get stuck. We’re here to help you understand just what’s going on with your vehicle’s battery and electrical system.

How exactly does a car battery work?

The car battery provides the jolt of electricity necessary to power all the electrical components in your vehicle. Talk about a pretty huge responsibility. Without battery power, your car, as you’ve probably noticed, won’t start.

How do I determine if my battery is too old?

For one thing, you can check the four- or five-digit date code on the cover of your battery case. The first part of the code is key: look for the letter and digit. A letter is assigned to each month — you know, like A for January, B for February and so on. The number that follows nods to the year, as in 9 for 2009 and 1 for 2011. This code tells you when the battery was shipped from the factory to our local Interstate Battery wholesale distributor. The additional digits tell where the battery was made. Car batteries last, on average, three-to-five years. Mind you, there are also weak battery signs to watch for, like a slow engine crank of low fluid level. If your battery case is swollen or bloated, there’s a smelly rotten egg scent coming from the battery or your check engine light appears, trouble may be beyond the bend. And if it’s over three years old? Consider it time for close monitoring.

How Often Do I Need a Car Battery Inspection?

The average car battery life is about four years. We recommend you have it checked every six months.
