Common Causes of Car Battery Failure


Car batteries wear down over time and need to be replaced every few years, but they don’t have to wear out sooner than that! By avoiding these five major causes of car battery failure, you can prevent premature wearing of your car battery and even extend its life. Let’s take a look at these causes of car battery failure and when to consider cheap car batteries.

Excessive Heat

Excessive heat can be a common cause for car battery failure. To avoid this, never leave your car in the sun or in an area with high temperatures for extended periods of time. You should also avoid parking your car near sources of extreme heat, such as fires and barbecues.

Incorrectly Installed Batteries

Incorrectly installed batteries are one of the most common causes of car battery failure. This can happen when a buyer fails to have a mechanic check their car before they drive it off the lot, or if someone installs their own battery incorrectly. In either case, the incorrect installation leaves the battery vulnerable and exposed to water or other contaminants that can cause corrosion and lead to breakage. If your car batteries are worn out, please consider cheapest car batteries and get them professionally installed.

Faulty Alternators

Faulty alternators are one of the most common reasons for battery failure. Alternators keep your car running by providing a steady supply of power that may not be available from your battery. If the alternator is faulty, it will overcharge the battery and eventually cause its cells to leak or explode. To prevent this from happening, make sure you’re getting regular alternator checks from a mechanic.

Improper Charging

Improper charging can lead to car battery failure due to overcharging or undercharging, which happens when a battery is either left on charge too long or not given sufficient time to fully recharge. To avoid this, make sure the battery is securely connected and the charger’s output voltage matches the battery’s voltage requirements. It’s also important that you don’t leave your car plugged in for an extended period of time, as this can lead to electrolyte boiling.

Poor Maintenance

One of the most common causes for car battery failure is improper maintenance. Keeping your battery clean and free from corrosion will go a long way towards extending its life. You can do this by using baking soda, water and a brush, or by taking it to an auto repair shop for professional attention. You should also keep the terminals clean, and make sure that the alternator is not overcharging or undercharging the battery.
