Most car batteries last 3 to 5 years. Warning signs include slow engine cranking, dimmer-than-usual lights, a clicking sound when turning the key, or a battery warning light on your dashboard. Cold weather can also temporarily reduce battery effectiveness.

If your battery is weak or dying, replacing it promptly prevents you from getting stranded. Castle Chevrolet McHenry stocks genuine batteries and can test yours for free to confirm whether replacement is needed.
