Our blog offers expert advice on starting a car with a low battery, including the top tips for jump-starting your vehicle.
It’s happened to the best of us – you’re out and about, trying to start your car, and the battery is dead. If you’re lucky, you might have a set of jumper cables in your trunk and can get a jump from a kindhearted stranger.
But what if you’re not so lucky? This article will teach you how to start your car using only a few household items with a low battery.
Steps on How to Start a Car With a Low Battery
If your car’s battery is low, you may be able to start it by jump-starting the engine. Follow these steps to do so:
- Park the working car next to the vehicle with the low battery, ensuring the batteries are not touching.
- Connect the positive (red) jumper cable to the dead battery’s positive terminal.
- Connect the other end of the positive cable to the positive terminal of the working battery.
- Now connect the negative (black) jumper cable to the working battery’s negative terminal.
- Finally, connect the other end of the negative cable to a metal surface on the car with the dead battery. This will help to ground the connection and prevent sparks.
- Start the working car and let it run for a few minutes. Then try starting the vehicle with the low battery. If it doesn’t start, you may need to replace the battery.
What to do if your car has a low battery?
If your car has a low battery, there are a few things you can do to try and start it. First, make sure that all of the lights are turned off. Next, try jump-starting the car with another vehicle.
If that doesn’t work, you can try using a battery charger. Finally, if none of those options work, you may need to replace the battery.
Why won’t my car start with a low battery?
If your car has a low battery, it may not start for various reasons. The most common sense is that the starter motor isn’t getting enough power to turn the engine over.
This can be caused by several things, including faulty batteries, loose connections, or a problem with the starter motor itself.
If you’re having trouble starting your car with a low battery, here are a few things you can try:
- Make sure all the connections are tight. Loose connections can prevent the starter motor from getting enough power.
- Try jump-starting your car. If the battery is dead, jump-starting may be the only way to get it going.
- Have the battery and starter motor checked by a professional. If they’re both in good working order, another issue may be causing your starting problems.

How to Charge a Dead Battery
It happens to everyone at some point—you go to start your car, and the battery is dead. If you’re lucky, it’s just a matter of jumper cables and a friendly neighbor. But if your battery is finished, you’ll need to charge it before starting your car.
Charging a dead battery is a simple process, but it requires a little bit of care. Follow these steps, and your car will be up and running in no time.
- Start by making sure that your battery is truly dead. A dead battery will show no voltage when tested with a multimeter. If you’re unsure how to test your battery, consult a professional.
- Once you’ve confirmed that your battery is dead, hook up your charger. Make sure that the red lead is connected to the positive terminal and the black information is connected to the negative terminal.
- Slowly charge your battery until it reaches 12 volts. Do not overcharge your battery, as this can damage it beyond repair.
- Once your battery has reached 12 volts, disconnect the charger and start your car. If your vehicle doesn’t start, you may need to jump-start it.
- Once your car runs, let it idle for a few minutes to allow the battery to charge.
- Drive your car for at least 30 minutes to fully charge the battery.
- If your car battery dies again, repeat the charging process. You may need to replace your battery if it fails a third time.
How to Keep Your Battery Healthy
It’s no secret that modern cars are packed with electronics. And while this makes for a more enjoyable and connected driving experience, it also puts a more significant strain on your battery.
So what can you do to keep your battery healthy and ensure it lasts as long as possible?
Here are some tips:
- Keep it clean – A pure battery will last longer than a dirty one. Make sure to clean off any corrosion that might build up on the terminals.
- Keep it charged – A car battery will self-discharge over time, so it’s essential to keep it up. If you’re not using your car regularly, give the battery a boost every few weeks.
- Avoid short trips – Starting and stopping the engine puts a strain on the battery, so try to avoid making short trips if possible. If you have to make a quick trip, ensure the engine is running for at least 15 minutes when you get back so the battery can recharge.
- Turn off electronics when not in use – Any electronic devices in your car (e.g., lights, radio, GPS) will drain the battery even when turned off. So be sure to turn them off when you’re not using them.
- Keep it excellent – Extreme heat or cold can shorten the lifespan of your battery, so try to keep it in a moderate climate if possible.
- Inspect it regularly – It’s a good idea to check your battery every few months to ensure it’s clean and free of corrosion. If you notice any problems, take it to a mechanic or auto parts store for further inspection.
Do I need to replace my battery if it won’t hold a charge?
If your battery doesn’t hold a charge, it may be time to replace it. Depending on the severity of the problem, you may get by with a simple jump-start or by charging the battery overnight.
However, if the problem is more severe, you may need to replace the battery entirely.
If you’re not sure whether or not you need to replace your battery, take it to a trusted mechanic or auto parts store, and they’ll be able to give you an accurate diagnosis.
