1. Find a clean flat surface where you can safely work on both vehicles at once.
You’ll need room for one car to be parked in front of or behind the other one so that jumper cables can reach both batteries at once.
2. Make sure this place isn’t near any trees or power lines.
3. Disconnect both cars’ negative terminals from their batteries using the screwdriver be careful not to touch any metal parts while doing so! Then connect them together using one set of.
4. Make sure your engine is off and that both vehicles are turned off as well. You don’t want to accidentally start up one or both engines when trying to charge your own battery.
5. Locate the positive and negative terminals for your battery, then connect the red cable from your booster pack (or jumper cables) to one terminal and the other end of that cable to one of the batteries in the other car.
6. Now take a look at both cars’ batteries and ensure they’re touching each other they aren’t, use some duct tape and cardboard scraps to bridge any gaps between them so they’re sided by side at all times during this process.
7. Connect one end of your second red jumper cable from your booster pack into this same positive terminal.
8. Attach one end of the red jumper cable to the positive terminal of your dead battery and the other end to your vehicle’s good battery. Do the same for the black jumper cable and negative terminals.
9. Make sure that all electrical equipment is off in both vehicles before turning them on again; turn them back on one at a time until they start up normally again
10. Start up your car, then start the engine with the good battery connected to your dead one.
The process should take about 10-15 minutes; if it doesn’t work after that time frame, you may have damaged your car’s electronics and need a professional mechanic’s help.
11. Check the level of fluid in your car’s battery. If it’s low, add distilled water until the fluid reaches the bottom of the filler neck.
How do you know your battery is dead?
There are a few different ways to tell if your car battery has died, but the easiest way is to just try turning the key in the ignition.
Then you know it’s time for a replacement. You can also check your headlights and see if they’re dim or flickering.
That means that your alternator isn’t charging properly and needs to be replaced as well.
How to jumpstart a dead battery without jumper cables?
If you are able to locate a set of jumper cables, you can use those to jumpstart your car by connecting them to the battery of another vehicle.
Once connected properly, start up the other vehicle and let it run for a few minutes before starting your own.
The alternator from the running vehicle will then send electricity to your battery and essentially recharge it.
Turn off the engine
In the other vehicle, disconnect the jumper cables and try to start your car.
If it starts, you should be able to drive to a repair shop where you can check your alternator with a multimeter.
Test your alternator
By asking your mechanic to use a multimeter to check the output of the alternator. If it is below 12 volts, that means that your alternator has died and needs to be replaced.
Get the vehicle ready to be jumped
Make sure that the car you are jumping from is running and has a good battery.
Turn off all electrical accessories in the vehicle that is being jumped. This includes the radio, air conditioning, and lights.
Check the battery connections
Make sure that the clamps from each battery are not touching any metal on either car.
If the batteries are side by side, make sure that there is no metal contact between them.
This is important to prevent a short circuit in your electrical system. Connect the cables.
The red cable goes on the positive post of each battery and the black cable goes on the negative post on each battery.
Clean the battery terminals
Clean the battery terminals with a wire brush and baking soda. If you have a battery charger, use it to charge the battery for 15 minutes before attempting to start the car again.
If your battery is still dead after these steps, take it to a mechanic for testing and replacement if needed.
Conclusion
A dead battery is a common problem that can be easily fixed at home with some simple tools and supplies.
You should be able to get your car up and running in no time.
