How do you fix a flat car battery?

A neighbor knocked on my door early this morning to tell me that my car lights were on—probably all night. By the time I got out to the parking lot to investigate, my car battery had gone flat. How do you fix a flat car battery?

I’m sorry to hear that this happened! Realizing you left your car lights on is a real bummer. Luckily, there are three ways you can fix your flat battery:
  • A
    jumpstart
    or booster pack will provide you with relatively quick power to get your car up and running again.
  • Adding distilled water to your battery can help if the electrolyte levels are low.
  • Using a battery charger can provide power for a few hours and may fully charge it.
Although these solutions will help you get your car running for the moment, you should consider testing and replacing your battery if necessary. Should your battery not be outputting enough volts, you’ll likely continue to experience inconvenient situations. It could also cost you more in the long run!
Even if your battery is still producing the correct voltage and you have no issues, consider adding a roadside assistance membership with
