Knowledge is Power (Battery Testing)

February 15, 2026

It’s likely happened to you once or twice.  You head to your vehicle, open the door, turn the key and… lo and behold, your battery is dead. Now you’re stranded, may have to get a jump or a tow, and you’ll definitely be late for wherever you were headed. While your vehicle may sometimes give you warning signs, other times it doesn’t.  

As many as one out of every four vehicles will have to have its battery replaced in the next 12 months.  If you don’t want to be surprised the next time your battery fails, consider having it tested.

There are different types of battery testing.  One measures voltage. Another checks for something called conductance.  By sending a certain type of electric current into the battery, it can measure how healthy your vehicle’s battery is.  There’s also a load test.  It checks how your battery is working while drawing power from it.  Newer test equipment found in professional service facilities can check for a number of different conditions using different methods. 

Most vehicle batteries last around five years.  It all depends on how you drive and in what conditions.  Extreme heat and cold will take their toll on a battery and shorten its life.  Stop-and-go city driving will also place batteries under more stress than smooth, continuous driving.  

So, what are some signs that your battery is starting to show its age? Well, the battery or alternator light may illuminate after you’ve started the vehicle or come on while you are driving.  If you’ve left lights or some equipment on and drained the battery, that can be very hard on it.

Because the battery is one of your vehicle’s most important components, it’s a good idea to have us check it regularly. In addition to examining the battery itself, a technician will also inspect the terminals and cables for corrosion, damage, fraying wires and loose connections.  It’s smart to have us do it before any extreme weather changes are expected or before long trips. In this case, knowledge truly is power.
