How to Know Your Battery Is Failing
A car battery rarely dies without warning. Learning to read the early signs can save you from being stranded and help you replace it on your own schedule rather than at the worst possible moment.
A Slow Engine Crank
If the engine turns over sluggishly when you start the car, the battery may be struggling to hold a charge. That slow, laboured crank is one of the most reliable early indicators.
Other Warning Signs
Dim headlights, a dashboard battery warning light, electrical glitches, or a swollen battery case all point to a battery near the end of its life. Most batteries last three to five years, so age alone is worth watching.
