Check the battery age too. If it is four or five years old, it may simply be near the end. Also look for corrosion on the terminals. Sometimes a cleaning helps, but if the battery is old and weak, replacement is usually the real fix.
How do I know if my car battery is dying before it leaves me stranded?
My car started slowly twice this week, but then it was fine. I don’t know if it is the battery, alternator, cold weather or something else.
Drivers share warning signs of a weak battery and when to test the battery, alternator and charging system.
Answers & Discussion
Cold weather exposes weak batteries. Mine started fine on mild days and struggled when the temperature dropped. I ignored it until the car died in a parking lot. Testing is cheaper and less stressful than waiting for a tow.
Slow cranking is one of the classic warning signs. I would get the battery tested before you wait for it to fail completely. Most parts stores or garages can test battery health quickly. If the battery tests good, then look at the alternator or starter.
