You don’t have to be a mechanic at an auto shop to understand the fundamentals of your vehicle’s battery. To help you make yours last, here are answers to a few of the questions you may have about it.

All You Need to Know About Car Batteries

What causes them to run out?

Time is the usual culprit behind a dead battery, since all units only hold charge for a certain period. Extreme temperatures, especially the cold, can also inhibit the chemical reactions in them, shortening their lifespans. 

How long should mine last?

If it’s new, your car battery should last roughly four to five years. In Wisconsin, which often faces extremely low and hot temperatures, the lifespan of your battery could be shortened to three years if you drive daily.

How can I make it last longer?

Anything in your car that uses power is using your battery. To make it last longer, roll down your windows instead of relying on your air conditioner during the summer. Consider using your sound system, seat warmers, and dome lights sparingly when the vehicle is off. Going on multiple short trips of 50 miles or less per week can cause acidic stratification, where the top part of the battery never gets a full charge. To avoid this, drive a greater distance at least once a month.

Can I throw away an old car battery?

Not with household trash. Lead-acid batteries can be toxic to individuals and wildlife, so you need to find a proper disposal location. If your local auto shop won’t take it, call the nearest recycling center, scrap yard, or hazardous material management facility to ask about disposing of your old battery.
