How to Jumpstart a Dead Battery


How to Jumpstart a Dead BatteryA dead car battery can be frustrating, as it will prevent your vehicle from starting. Fortunately, in most cases anyway, a dead battery can be jumpstarted to get the car up and running again, which in turn will recharge the battery. Signs of a dead or dying battery include a slow or non cranking engine and dimming lights. While it is true that a battery will need to be replaced at the end of its life, which is a timeframe that varies based on the brand you purchased, many times a battery will die due to leaving lights on, a door ajar or playing the radio without the engine running. If that's the case you're looking at, jumpstarting will get you back on the road.

Jumpstarting involves using a vehicle with a healthy battery and jumper cables to give your battery a boost. Here's a quick rundown on how to properly conduct this process. Remember, you'll need a vehicle with a healthy battery and a set of jumper cables.

  • Park the healthy vehicle in a manner that will allow your jumper cables to connect between its battery and the dead battery. Turn the engine off after parking.
  • Attach the positive (red) cable to the positive battery terminal on the healthy car. Then connect the other end of the red cable to the positive terminal on the dead battery. Don't be alarmed if there are a few sparks.
  • Repeat the above process but with the negative (black) cable. First connect the healthy side, then connect to dead battery. Again, sparks may be present.
  • Start the engine on the healthy vehicle and allow it to fun for a few minutes.
  • After a couple minutes start the engine on the vehicle with a dead battery. After it starts let the engines on both cars run with the cables connected to ensure the dead battery is charged.
  • Remove the cables in the reverse order that you attached them.

At this point you will be good to go! However should your vehicle's battery die again shortly thereafter, you may be looking at a bigger issue, such as a failed alternator or a battery at the end of its lifetime.
