We’ve all been there. You’re running late for work and you get in your car only to realize that your battery is dead. If you’re lucky, you have jumper cables or someone nearby who can give you a jump start.
But what if you don’t? Is it really worth the risk to leave your car running while you charge your battery?
If you’re like most people, you probably think it’s a good idea to leave your car running to charge the battery. After all, it makes sense that the engine would generate enough power to keep the battery charged, right? Unfortunately, that’s not how it works.
In fact, leaving your car running can actually damage your battery and shorten its lifespan. Here’s why: The alternator is what actually charges the battery while the engine is running. But if the battery is already low on power, the alternator has to work harder to recharge it.
That extra strain can damage the alternator or even cause it to fail prematurely. Even if your alternator is up for the task of recharging a low battery, leaving your car idling wastes gas and emits harmful pollutants into the air. So next time your battery needs a boost, just turn off the engine and let it charge while you’re doing something else.
Your wallet (and the environment) will thank you!
