Queensland Summer Is Your Battery's Biggest Enemy
Most drivers blame cold mornings for flat batteries. In Brisbane and on the Gold Coast, the real culprit is summer heat. Heat speeds up the chemical reactions inside a car battery. That makes it age faster, lose charge while parked, and fail without much warning. Battery industry research suggests that, as a rule of thumb, every 10°C rise in average temperature can roughly halve a battery's life. Under the bonnet, temperatures can climb to around double the air temperature outside, so a 35°C day in Logan or Southport can mean serious heat around your battery. High temperatures also cause battery fluid to evaporate, speed up corrosion on the terminals, and encourage sulfation, a build-up that permanently reduces how much charge the battery can hold. Running the air-conditioning hard on long, hot drives adds even more load. The tricky part is that heat damage is silent. Your car might start perfectly all summer, then refuse to turn over on the first cool morning. That is why the ho...
