Signs and Symptoms of a Failing Car Battery
A car battery can fail for a variety of reasons, including age, wear and tear, and improper maintenance. Here are some common signs and symptoms that indicate a car battery is failing:
Slow Engine Crank
If your engine takes longer than usual to crank when you turn the key, it could be a sign that your battery is losing its charge. This is often caused by a weak or old battery, which may not have enough power to turn the engine over quickly.
Dim or Flickering Headlights
If your headlights are dimmer than usual or flickering, it could be a sign that your battery is struggling to provide enough power to the electrical system. This is often caused by a worn-out battery or a loose connection.
Dead Battery
If your battery is completely dead, you may not be able to start your car at all. This is often caused by a faulty alternator, loose connections, or a worn-out battery.
Swollen or Leaking Battery
If your battery is swollen or leaking acid, it’s a clear sign that it needs to be replaced immediately. A swollen or leaking battery can cause serious damage to your car’s electrical system and even lead to a fire.

Regular Maintenance
Check the Battery Terminals
Regularly check the battery terminals for corrosion and clean them if necessary. Corrosion can prevent the battery from functioning properly and reduce its lifespan.
Check the Battery Fluid
Check the battery fluid level regularly and top it off if necessary. Low fluid levels can cause the battery to overheat and reduce its lifespan.
Driving Habits
Avoid Deep Discharging
Avoid deep discharging your battery by turning off the engine when the car is parked. Deep discharging can reduce the battery’s lifespan and cause it to fail prematurely.
Avoid Extreme Temperatures
