how to use jumper cables
To jump start a car, you'll need jumper cables, also known as booster cables, to connect the dead battery to a fully charged battery in another vehicle. Here are the steps you can follow:
- 1. Position the vehicles: Park the vehicles close enough together so the jumper cables can reach the batteries. Turn off the ignition and emergency brake in both vehicles, and turn off all accessories.
- 2. Locate the battery terminals: Open the hoods of both cars and find the battery terminals, which are usually red or black with a + (red) and – (black) sign on top.
- 3. Connect the jumper cables: In the correct order, connect the cables as follows:
- Red to dead: Connect the red clip to the positive terminal on the dead battery.
- Red to donor: Connect the red clip to the positive terminal on the working battery.
- Black to donor: Connect the black clip to the negative terminal on the working battery.
- Black to metal: Connect the black clip to an unpainted metal part of the dead car, like a bolt or bracket.
- 4. Start the engine: Start the working car and let it run for a couple of minutes. Then, start the car with the dead battery and let it run for a couple of minutes.
- 5. Disconnect the cables: Disconnect the cables in reverse order, first disconnecting the black cables, then the red cables. Keep the clamps from touching while any part of the cable is still connected.
- 6. Drive the car: Drive the car for about 30 minutes to help it recover.
It's important to connect and disconnect the cables correctly to avoid damaging the electrical systems or batteries.
at what voltage is a car battery dead?
A car battery is considered dead when its voltage drops to 11.9 volts or below. A fully charged 12-volt car battery should have a voltage of around 12.6 volts. Here are some other things to know about car battery voltage:
- Voltage while driving: A healthy car battery should have a voltage of 13–15 volts while running.
- Charging: It can take 4–8 hours to charge a car battery enough to start the car a few times, and 10–24 hours to fully charge it.
- Testing the alternator: To test the alternator, start the car and turn on all the electrical equipment. If the multimeter reads below 13.5 volts, the alternator might need to be replaced.
- Battery warning light: If your car has a battery warning light, it usually indicates a voltage issue.
- Battery damage: If your car battery's charge drops too low, it can become damaged and you won't be able to start your car.
signs of a bad car battery vs alternator
Here are some signs of a bad car battery versus a bad alternator:
- Engine cranking: A bad battery will cause a slow engine crank or no crank at all, while a bad alternator can cause the engine to start but then stall immediately.
- Battery warning light: A lit battery warning light while driving indicates a problem with the alternator.
- Dim lights: Dim headlights and interior lights can be a sign of a bad alternator or battery. However, a bad alternator can also cause lights to fluctuate between dim and bright.
- Burning smell: A burning smell that smells like rotten eggs could indicate a damaged or leaking battery.
- Strange noises: A bad alternator can cause strange rattling noises while driving, which can indicate bearing failure in the engine.
- Dead battery: A dead battery can be a sign of a failing alternator, as a failing alternator can't fully charge the battery.
how do you know your car battery is dead
Here are some signs that your car battery is dead or dying:
- Slow engine start: The engine cranks slowly or sluggishly when you try to start the car.
- Dim headlights: The headlights lose their brightness because the battery can't provide enough power.
- Check engine light: The check engine light flashes when the battery power is low.
- Electrical issues: General electrical problems can affect the dashboard or electrical system.
- Battery corrosion: Corrosion on the battery terminals and/or cables indicates that acid is present, which shouldn't be there.
- Ignition clicks: A clicking noise when trying to start the car could be caused by a dead battery, loose wiring, a faulty starter motor, or an ignition switch.
- Bulging battery case: A bulging battery case means the cells inside are swollen and about to rupture, which can be a fire hazard.
- No start: The car won't start.
- Odd smell: The battery has an odd smell.
- Battery is old: The battery is old.
- Vehicle starts, then dies immediately: The vehicle starts, but then dies immediately.
Can cold weather cause car problems?
Cold weather can cause a number of problems for your car, including:
- Battery: Cold temperatures can slow down the chemical reaction in a battery, making it harder to start the car or run its systems. Older batteries are more likely to fail in the winter.
- Tires: Cold air causes air to contract, which can lead to under-inflated tires. This can cause poor handling, reduced fuel efficiency, and tire blowouts.
- Fuel lines: Moisture in the fuel system can freeze, preventing the engine from getting enough fuel.
- Windshield wipers: The rubber on windshield wiper blades can become brittle in sub-freezing temperatures.
- Door locks: Door locks can freeze, making them difficult to open.
- Oil: Oil thickens in cold weather, so you can consider switching to a low-viscosity oil or synthetic oil for the winter.
- Infotainment system: The LCD screens in your infotainment system may not respond as well in cold temperatures.
- Corrosion: Road salt can build up on your vehicle and cause corrosion.
- Spark plugs: Old, corroded spark plugs may not perform well in the winter.
- Belts: Older drive belts can become stiff in cold weather, making it harder for them to grip the pulleys.
Here are some tips to help prevent car problems in cold weather:
- Check your tire pressure more often
- Use a de-icer on your door locks
- Use silicone spray, WD40, or cooking spray on your windows and locks to prevent freezing
- Slide old socks over your windshield wipers to prevent icing over
- Let your engine idle for 30 seconds before driving
My car is stuck in the snow
Here are some things you can try if your car is stuck in snow:
- Turn off traction control: Traction control prevents your tires from spinning, so you'll need to turn it off to regain control of your vehicle.
- Release air from tires: Slightly deflating your tires can help you gain more traction.
- Clear space around tires: Dig away snow and ice from around your tires, especially in front of and behind the drive tires. This will give you space to move your car back and forth.
- Add traction with kitty litter: Kitty litter can help your tires get more traction and can also melt snow and ice.
- Avoid flooring the gas pedal: Sudden acceleration can cause your wheels to spin and get stuck.
- Ask for help: If you don't have the resources to get unstuck, ask other motorists or neighbors for help.
- Use snow chains: Snow chains are a series of chains that fit over your wheels to provide more traction.
