If your vehicle’s battery has ever died or started acting up during a heatwave, you’re not alone. Here at Joe’s Slinger Service in Slinger, WI, we see a noticeable uptick in battery issues every summer — and there’s a good reason why.
Warm weather causes the chemical reactions inside your car battery to speed up. While that might sound like a good thing, the added heat actually generates excess internal pressure. This can lead to battery fluid evaporation, swelling, or even corrosion at the terminals. Over time, that kind of strain shortens your battery’s lifespan and increases the risk of failure — often without much warning.
On the flip side, cold temperatures can slow down those chemical reactions, making the battery sluggish but less likely to overheat. That’s why heat is actually harder on your battery than cold.
Tip: If you live in Slinger, anywhere in Washington County, it’s a good idea to have your battery tested during routine maintenance — especially before or during the hot summer months. A quick check now could save you from a dead battery later.
