[VIDEO] Corvette Mechanic Paul Koerner Discusses Battery Maintenance


With many of you storing your Corvettes or driving them only on nice days through the winter months, your battery may be losing voltage unless you are doing periodic battery maintenance. And if you think just cranking her up and letting the alternator recharge the battery, listen to what GM World Class Technician Paul Koerner of Jackson Chevrolet in Middletown, CT has to say about battery maintenance.

As Paul is going through the process of maintaining the batteries on a Black 2013 Corvette 427 Convertible and a C7 Corvette Z06 at his dealership, he made this video which was posted to his The Corvette Mechanic facebook page that explains battery maintenance and why it’s so critical to the electrical system.

As you turn the key or push the start button in your Corvette, you are taking electricity from your battery to start and run the engine, and provide power to all the electrical accessories inside the vehicle. Paul tells us that the function of the alternator is to supply additional on-demand power when needed, so with a battery that has lost voltage, the alternator needs to work harder to supply the needed power.

So not only does battery maintenance save you from a dead battery, but it can also extend the life of your Corvette’s alternator! Here’s Paul Koerner on battery maintenance:

We cover battery maintenance and why allowing your alternator to recharge a weak battery can have expensive consequences.


Paul did a video on Battery Maintenance a few years ago with Mid America Motorworks so check that out if you want more info on the subject.

  1. How is all this battery maintenance affected by the fact that whenever my Corvette is garaged, I always have it hooked up to a Corvette trickle-charger?

  2. What can I do to maintain my battery on my 2017 Z06 that I have stored in a self storage building that doesn’t have power to it ? I start it every week and run it for at least 20 min and water temp come up to 200 degrees .

  3. I call BS (baloney salad)!
    Alternators may “wear out,” but when they do it’s the bearings or the drive belt that go. To say the alternator has to work harder is just plain silly. The alternator, at a little faster than idle, produces ample power to run the car’s electronics and charge the battery…even a borderline battery. And the battery’s only real job is to start the engine — electrically, the alternator does the rest (including charging up the battery for the next start).
    Many people don’t get that car batteries wear down the most in the heat of summer; the heat is the killer. We don’t find out that they’re worn down, though, until winter — when the engine (because of cold, oil viscosity, etc.) is much harder for the starter to turn over, which puts lots more strain on the (summer heat-weakened) battery.

  4. A battery tender (not charger) kept plugged in and attached to the battery is a much better option for battery health than a monthly charge for 20 min. I keep them on all my vehicles and motorcycles even if they are not going to be used for only a few days. Harley-Davidson makes a couple of good ones that I even use on my cars.
