Hot Tips for Summer Battery Care

Understanding Summer Battery Challenges

While extreme cold is often associated with battery issues, high temperatures can also pose challenges for car batteries. Heat accelerates chemical reactions inside the battery, leading to increased fluid evaporation, which can result in reduced electrolyte levels and diminished battery performance. Additionally, heat can cause battery casing expansion, leading to potential damage and internal short circuits.

Perform Regular Inspections

  • Start your summer battery care routine by conducting regular visual inspections of your car's battery.
  • Check for signs of corrosion on the battery terminals and cables, as well as any cracks or damage to the battery casing.
  • Ensure that the battery is securely mounted in place and that all connections are tight and free of debris.

Monitor Fluid Levels

  • If you have a traditional flooded lead-acid battery, check the electrolyte fluid levels regularly, especially during hot weather.
  • Use a battery hydrometer or look for built-in level indicators to determine if the electrolyte levels are within the recommended range.
  • Top up the fluid levels with distilled water if necessary, being careful not to overfill.

Protect Against Heat

  • Shield your battery from direct sunlight and heat by parking your car in shaded areas whenever possible.
  • Consider using a battery insulator or heat shield to help regulate temperature fluctuations under the hood.
  • Avoid exposing the battery to extreme heat sources, such as engine exhaust or hot pavement, which can accelerate fluid evaporation and cause damage.


The engine can also suffer consequences during the extreme heat of the summer months. Maintain yours with the top synthetic oil in Kyle, AMSOIL's Signature Series 0W-20 Synthetic Motor Oil.


Reduce Electrical Load

  • Whenever possible, minimize the use of non-essential electrical accessories, such as air conditioning, entertainment systems, and charging devices, especially when idling or parked.
  • Turn off headlights, interior lights, and other accessories when the engine is not running to reduce unnecessary drain on the battery.

Avoid Deep Discharges

  • High temperatures can increase the rate of self-discharge in batteries, especially if they are left unused for extended periods.
  • Avoid letting your car sit idle for too long without starting it, as this can lead to deep discharges and reduced battery capacity.
  • Consider using a battery maintainer or trickle charger to keep the battery topped up if your car will be parked for an extended period.

Professional Inspection and Testing

  • If you notice any signs of battery weakness or if your car is experiencing starting issues, have the battery tested by a professional technician.
  • A battery load test can help determine the battery's health and capacity to hold a charge, allowing you to address any issues before they worsen.

Consider Upgrading to a High-Performance Battery

  • If you live in an area with extremely hot summers or frequently experience battery-related issues, consider upgrading to a high-performance battery designed to withstand higher temperatures.
  • AGM (Absorbent Glass Mat) batteries and gel batteries are known for their superior heat resistance and durability, making them ideal for summer driving conditions.
