How Long Do Batteries Last?

Average Battery Lifespan

There are tons of factors that go into determining a battery’s lifespan, and many come from your own driving habits. Much like other parts, your battery’s performance is improved with good habits and practices. Here’s the basics you need to know.

Rough estimates put a battery’s life at close to four years, though they can last longer or shorter. If your car remains parked and not in use for extended periods, the battery will self-discharge over time. The same is true for cars that make frequent short drives.

Leaving the battery in use while the car isn’t running will drain the battery especially quickly. This includes leaving the key in the ignition and leaving a light on overnight, including interior and exterior lights. General use will wear down a battery eventually, though these extra strains will have you needing a new one sooner.

Signs I Need Battery Replacement

Many times, drivers only find out they need a new battery when it’s too late and their car won’t start. When you know the warning signs of a weak battery, you can anticipate your battery replacement in advance. Here’s what you can do to check your battery’s health.

• Your Car Takes Longer To Start- While your car not starting at all is an obvious sign of battery failure, a slower start is likely due to a weakened battery.
• Interior Lights Are Dimmer- If you notice that your lights aren’t as bright as they used to be, they may not be getting the same level of energy from your battery.
• Signs of Damage- If you have even a slight suspicion of your battery’s health, pop your hood and give it a quick look. Cracks and visible corrosion on the battery should be addressed right away. You may also smell a sulfur-like odor, which is an effect of further battery damage.
