Battery Testing & Replacement

Car battery testing and replacement in Winthrop Harbor

Quick answer

Wenzel's Automotive in Winthrop Harbor tests and replaces car batteries, and checks the starter and charging system so the new battery stays charged. A battery test is quick and shows whether the battery can hold a charge before a cold morning finds out for you. Call (847) 872-1111.

Cold weather and batteries

Cold slows the chemistry inside a battery at the same time it makes the engine harder to turn over. A battery that starts the car in October can leave you stuck on the first January morning near zero. A fall battery test finds the weak ones before winter does.

Battery, alternator or starter?

A dead battery is sometimes the symptom and not the cause. A weak alternator lets the battery run down while you drive, and a parasitic drain can empty a good battery overnight. We test the charging and starting systems along with the battery so the fix lasts.

Battery Testing & Replacement questions

How long does a car battery last?

Many batteries last three to five years. Heat, short trips and cold winters all shorten that. A test shows how much life is left.

Why does my car keep needing a jump?

A weak battery, a charging problem, or something drawing power while the car is off. We test all three to find which one it is.

Can you test my battery while I wait?

Yes. A battery test is quick. Call (847) 872-1111 and we will set a time.
