What Extreme Temperatures Do to Your Car Battery

Extreme temperatures, whether hot or cold, have a negative impact on your car battery. We want our customers to be well-informed as they search for a new vehicle. Therefore, we have explained what extreme temperatures do to your car battery and how you can minimize the negative effect.

Cold temperatures decrease battery capacity. Hot weather increases battery capacity but damages its lifespan. Other negative affects cold weather has on a lead acid battery in the winter are increased draw from starter motors and other accessories. Oil thickens in cold weather, which makes it more difficult for the engine to turn over. In hot temperatures, battery life halves for each increase of 15 degrees over 77 degrees Fahrenheit. Some ways that you can help protect your battery from extreme temperatures are topping up the electrolyte when needed, avoiding overcharging the battery, and keeping the battery charged during cold weather.

Extreme temperatures can damage or kill your car's battery, so it's important to know the effects it has. You can contact our service center at Duncan Acura if you have any questions about batteries or other car-related concerns.
