Car Battery: How to Test It and When to Replace It

Most batteries give up in winter, but the damage starts in summer. One simple test tells you whether you can count on it for another season.

In this article, our workshop team explains step by step what to watch out for, so you can make the right decisions for your car and avoid unnecessary costs down the line. The recommendations below are based on our team's day-to-day experience in the shop.

What to keep in mind

• A battery lasts four to five years on average
• Resting voltage should be above 12.4 V
• A load test shows the real capacity under draw
• Corroded terminals raise resistance and stop the battery charging properly
• Slow cranking and dimming headlights announce the end

Bottom line: prevention is always cheaper than repair. Book a check-up at our shop and enjoy professional diagnostics, warrantied parts, and transparent advice. Book online in just a few minutes.
