There are plenty of signs of a bad car battery, so if you’re having any of these issues, you should get to your dealership or mechanic and have your battery checked stat.
If it takes a long time for the engine to turn on when you turn your car key, you might be having battery issues. You may also notice your check engine light comes on occasionally. Whether it’s the battery or a problem with the engine or transmission, you should see your mechanic in these cases no matter what.
When you check your fluids, make sure you’re keeping an eye on the battery fluid level. If the fluid gets below the lead plates inside, you should have your battery checked. You could also have a battery leak, which will lead to corrosion and could mean you have to replace the battery.
Finally, your battery will eventually just get old, so have your battery inspected every year!
