A dead car battery can leave you stranded and stressed. Knowing what to do can save you time and hassle.
Car batteries can die for many reasons. Sometimes it’s due to leaving the lights on. Other times, it’s because the battery is old. When this happens, you need a plan. First, stay calm and check if the lights or radio work.
If not, your battery is likely dead. Next, find a friend or neighbor with jumper cables. Connect the cables to your car and their car following the correct order. If you don’t have cables, consider calling for roadside assistance. Another option is to use a portable jump starter. Regularly checking your battery can prevent future issues. Stay prepared and keep your car running smoothly.
