If you find yourself in a situation where you need to jumpstart your car, there are a few household items that can help you out. First, you'll need some jumper cables. If you don't have any, you can try using a set of alligator clips. These can be found at most hardware stores.
Next, you'll need something to use as a power source. This can be another car with a working battery, or even a lawn mower or other small engine. If you're using another car, make sure that both cars are turned off and the keys are out of the ignition before attaching the cables.
Once everything is hooked up, start the working car and let it run for a few minutes before starting your own car. This will give the dead battery time to recharge slightly so that it's easier to start.
If jumpstarting your car doesn't work, or if it seems like the battery is completely dead, you may need to replace it entirely.
