How to Jump Start a Car with a Dead Battery
  • If you look at your battery, there will be two posts on the top of the battery. There should be indicators as to which side is positive and which side is negative by either a positive sign and a negative sign. The side is always coloured as RED and the side is always coloured as BLACK.
  • The same will be indicated for the and the side for your cables and there will be one black one and one red one. For your battery to charge, there must be a positive and negative current flowing from the other vehicle to yours, or the battery pack to your vehicle.

Before You And Your Helper Begin The Jump

  • Read your owners manual, first. Your manufacturer may advise against jump starting a vehicle due to sensitive electronic circuitry.
  • Dont try to jump a frozen battery.
  • Do NOT jump a battery that is cracked or leaking. This is very dangerous. You will need to purchase a new battery at this point, so call a tow truck or a friend that can help you out.
  • Ensure that the battery isnt dry. Check individual cells for fluid levels and add water accordingly. Check your owners manual for details and warnings.
  • If there is corrosion on the battery, try to clean it off with a wire brush, aluminum foil or anything but your hand as the chemicals can be damaging to your skin. Be sure you cover your nose and mouth to avoid inhaling the dust as it is a lung irritant.
  • Once you begin the process of hooking the cables up NEVER allow any of the hook-up clamps to touch. Each person should hold an end of the cables and keep the two clips separate .

How To Test The Battery In Pacifica

The easiest method to check the 12v battery in Pacifica is by measuring the voltage with a multimeter. A healthy battery should have 12.6 volts or more when fully charged. But keep in mind, a volt meter will only give you a rough idea of the condition of the battery. Sometimes a battery showing over 12.4 volts may not be able to supply enough current to crank the engine.

Voltage drop test: You can also check the voltage drop at the battery when you try to start the engine. If the voltage drops too much, below 10 volts, your battery doesnt have enough charge to start the engine. This can happen due to internal degradation of the battery, if the vehicle has been sitting for a long time, or if the alternator in your Pacifica has malfunctioned and not charging the battery properly.

Position The Booster Vehicle

First, park a vehicle with a full battery close to the car with the discharged battery. The vehicles can be beside each other or facing bumper-to-bumper. They must be close enough to allow the jumper cables to reach the batteries.

Shut off the ignition on both cars and remove the keys. Set the emergency brake in both vehicles. Turn off all accessories, including climate control, lights, and radio.

Note: Most gasoline-powered vehicles have batteries under the hood. However, the battery is found in the trunk or under the back seat in some models. Arrange the car with its good battery accordingly. Check the vehicles manual if its battery location isnt known.

Maintaining Computer Memory When Changing The Battery

Replacing a battery in an older vehicle is simple remove the cables and hold down and swap in the new battery. But if youre changing a battery in a vehicle built after 2000, a jumper pack and power adapter cables are good tools to have on hand. Thats because newer vehicles require backup power to maintain the learned calibrations for the electronic throttle body, anti-pinch windows, power sliding door, HVAC actuators, theft-deterrent radio and security system. If you dont provide backup power, the vehicle will forget the calibrations when you disconnect the old battery. Then, when you connect the new battery, the vehicle may not start or may run so poorly that it has to be towed to a shop. Some vehicles require costly dealership-only recalibration with a factory scan tool. Others will run poorly until they eventually relearn.

You can avoid all those recalibration issues by providing backup power to the vehicle while you change the battery. Use your jumper pack with a special cable . Find the OBD II diagnostic port on your vehicle and push the D-shape connector onto the port. Plug the other cable end into a jumper pack or emergency and recreational portable power pack. Then remove the battery cables and insulate each one with electrical tape or shove them into a nonconductive cover to prevent shorting.

Clicking Noise And No Start

The leading cause of clicking noise and no start in Range Rover is weak battery. If you hear clicking noise from the engine compartment when you try to start the vehicle, it indicates that there is enough charge in the battery to activate the solenoid , but not enough charge to power the starter. The starter motor requires high electric current to turn over the engine, whereas lights and wipers take very little current to operate so dont rule out weak battery even if electrical accessories work normally in your Range Rover.

How To Avoid A Dead Battery

Cars need to be driven regularly to allow the alternator to maintain the batterys charge level. If you need to park your car for an extended period, consider using a trickle charger or battery maintainer. These devices can replenish a drained battery. The better models can replenish the battery and potentially extend its service life.

Car batteries typically last three to five years, according to AAA, depending on use and temperatures. Hot weather is far worse on battery life than cold weather.

Routine inspection is as important for the battery as it is for the rest of the car, says CRs Banta.

To avoid being stranded, you should be diligent about servicing and replacing your cars battery, Banta says. He recommends having the battery load tested annually after its 2 years old if you live in a warmer climate and 4 if you live in a colder climate. Doing so tests its ability to hold voltage while being used, and the results will let you know when its time to start shopping for a replacement.

It’s better to careful about maintaining and replacing your battery than stretching every last start from it and risking being stranded.

Some auto parts stores, like AutoZone, will test your battery free of charge and install a replacement if needed.

    Ten Steps To Jump Start A Car

  • Before starting, make sure any electrical systems or devices in the vehicle with the dead battery are switched off and if possible, lower the drivers window.
  • Park the second vehicle as close to the casualty vehicle as possible, without the vehicles touching, ensuring the jump leads will comfortably reach from one battery to the other.
  • Ensure both vehicles engines are switched off, remove the ignition keys and open their bonnets .
  • Attach one end of the red jump lead to the positive terminal on the flat battery. The positive terminal will usually have a red plastic cover with a plus symbol on it. Pull the cover back to access the terminal.
  • Then attach the other end of the red jump lead to the positive terminal of the good battery on the second vehicle.
  • Attach one end of the black jump lead to the negative terminal of the good battery.
  • Then attach the other end of the black jump lead to a good earth point on the casualty vehicle a solid metal part of the engine is usually best.
  • Now attempt to start the casualty vehicle. If it doesnt start after a few attempts, it might be more serious than a flat battery. In this event, seek professional help by .
  • If it does start, leave it running for about five minutes.
  • Switch off the casualty vehicle, disconnect the negative jump lead then check the engine starts again okay. Disconnect the remaining jump leads.
  • What Is A Ground Connection

    The negative terminal of the battery is connected to the body/chassis of Range Rover, called a ground connection. The engine also requires a ground connection to function, but the way the engine is mounted, it does not allow the electric current to flow between the engine and the body . For this purpose, a ground strap/wire is used to connect the engine and the chassis.

    How To Boost A Dead Vehicle Battery

    Boosting a dead battery is relatively easy, since most passenger vehicles have a battery with the same voltage of 12.6 volts. You just have to find one to boost your dead battery. Once you flag someone whos willing to help, place the boosting vehicle close to the vehicle with the dead battery, ensure they do not touch, place them both in park or neutral, and put the parking brakes on and turn off the engines. Next, follow these steps:

  • Clean the terminals of both batteries before you begin. Steel wool can do the trick, but if the terminals are only slightly dirty, you may just need a paper towel or rag to clean them. Ensure terminals are clean so you have a solid connection going from the boosting battery to the dead battery.
  • Find the positive and negative terminals. The positive terminal will have either POS or + beside it and the negative terminal would have either NEG or – beside it. The positive terminal is also thicker in diameter than the negative terminal.
  • For the dead battery vehicle, ensure all plug-in accessories are unplugged, such as phone charger or GPS. Turn off vehicle accessories as well, such as climate controls, wipers and stereo. This allows all of the charge to go directly to starting the engine of the dead battery and nothing else.
