How the Summer Heat Can Affect Your Car Battery

Is your car slowing down in the summer? It could be because you have not gotten an oil change done on time. Or worse, you may have skipped your battery replacement date. It is well-known the high temperatures experienced during the summer season exert more strain on car batteries compared to the cooler temperatures of winter. As counterintuitive as it is, it is true that high temperatures exert a more pronounced influence on the chemical processes involved in power generation. The soaring heat outside can intensify the thermal load on the engine compartment and hasten the occurrence of battery malfunction. Consequently, a considerable number of car drivers find themselves stranded on the side of the road during the summer months. In this blog, we tell you how and why the heat affects car batteries, and what must be done to mitigate the consequences.

The Hot Weather and Your Car Battery

Similar to the human body’s reliance on fluids to maintain optimal functionality in high temperatures, the car battery also necessitates fluid to operate efficiently. Battery fluid comprises sulfuric acid and water, which initiates and propels the chemical reaction responsible for the ignition and propulsion of a car.

In the event of low battery fluid levels, the battery’s charge diminishes, resulting in suboptimal performance and potential complete failure. Insufficient levels of fluid may result in permanent corrosion impairment to the internal configuration of your battery. The corrosion of car batteries is a natural phenomenon that can be accelerated by factors such as elevated temperatures and insufficient electrolyte levels.

Battery Evaporation

Conventional maintenance of a flooded When it comes to car knowledge, most individuals are aware with the words “flooded” and “sealed” batteries. Conventional maintenance of a flooded car battery consists of periodically filling the cells with water. However, evaporation remains a problem as the summer’s scorching weather persists. consists of periodically filling the cells with water. However, evaporation remains a problem as the summer’s scorching weather persists.

In warm temperatures, battery life decreases due to the continual evaporation of the battery’s internal fluids. The battery loses its ability to conduct electricity and take a charge as the liquid evaporates.

Heat And Car Batteries: Signs to Watch Out For

Now that you know your battery might be damaged by heat, the next question is how to recognize a dying battery. Keep a watch out for these typical symptoms:

  • Reduced cranking speed during ignition
  • Dimmer headlights or interior lights
  • Clicking sound during ignition
  • Illuminated check engine or battery light, low battery fluid, misshaped or bloated battery case
  • Corroded battery terminals

Consider having your battery tested or opt for battery replacement if you see any of these warning signs.

What You Can Do

It is advisable to not delay until the onset of summer’s high temperatures to impact your car battery. There exist numerous measures that can be taken to ensure optimal functionality of one’s battery.

Keep It Clean

Avoid getting dust or dirt on the battery’s top. A battery’s power may be diminished by the accumulation of grease and grime. Check the battery regularly for dirt and wipe it off right away if you find any.

Watch For Corrosion

Because of the rise in temperature, the internal components of your car battery may corrode and restrict current flow. Keep an eye out for rust while inspecting your batteries. Use a scouring pad or copper brush to remove the rust and corrosion.

Check The Water Level

The electrolyte water in a lead-acid battery might evaporate in the summer heat. If the water in any of the cells is low, replace it with only clean water.

Look For Damage

Ensure the longevity of your battery by carefully inspecting for any indications of leaks, cracks, or bulges. Don’t get caught in a sticky situation. Keep an eye out for these tell-tale signs and replace your battery before it’s too late.

Battery Testing

Premature battery failures may be detected with the use of battery testing. As a result, motorists should bring their vehicles into a service centerregularly to have their batteries tested. Furthermore, ensure to get your vehicle inspected for mechanical and electrical repairs. This will keep you mobile and safe from extra expenses and breakdowns.

After all, nothing is more of an inconvenience than a battery that can power the lights but not the engine.
