Knowing when to replace your car battery is essential for your vehicle’s performance. A failing battery can leave you stranded.
Car batteries don’t last forever. They have a limited lifespan. Over time, they lose their ability to hold a charge. Several signs indicate your battery might need replacement. Slow engine crank, dim lights, and frequent jump-starts are common symptoms. Pay attention to these signs to avoid unexpected breakdowns.
Regularly check your battery’s age. Most car batteries last between three to five years. Extreme temperatures can also affect battery life. If your car struggles to start, it might be time for a new battery. Don’t wait until it’s too late. Knowing the signs can save you from inconvenient and costly repairs.
