A Car Battery Is Dead-Introduction, Restarting And Charging

A Car Battery Is Dead-Introduction, Restarting And Charging

Page view

  Although car batteries can last for years they seem to die at the most unexpected time. Almost 100 million auto batteries are replaced every year. Even though there are many causes of a dead battery, the shortcomings of the factory are rarely to blame. Knowing how the car battery functions and steps to follow if it fails can get you back on the road as faster as possible.

  A car battery can die for various reasons.

  Freezing temperatures

  Leaving lights on, music system on and air conditioner

  Turning on systems that consume energy when the car is not running

  After storing the vehicle for a long time

  Alternator failure

  Short circuit

  Sulfate build up on the plates

  Car battery is dead what to do?

  Inspect The Battery

  The first step is diagnosing your battery, this will give you a glimpse of what might be wrong and what you can do to salvage the situation. You can check for faults cracks, rusty terminals, cut wires, or leaking liquid.

  Check The Alternator

  A bad alternator can also cause your battery to stop charging and die right away. You need to check if it has any issues for you to move to the step. This is a common problem in vehicles with over 100,000 miles on them. An alternator provides electric energy that helps to charge your car. If no energy is coming out of the alternator the battery does not charge.

  Clean Rusty Terminals

  Use baking soda and water r to scrub the terminals clean, then put some petroleum jelly on top of the posts.

  Get A New Battery

  If you think the problem is deeper you should always replace the battery even if it seems to be working. This is for the safety of both your system and you.

  Restore The Battery To Its Original Charge

  You can restore the battery to a full charge by have it connected to an external power supply. The best option and easiest way are to use a trickle charger. It provides a small amount of power that restores the charge over time. You can get this device from any automotive parts store.

  You can also restore it by topping up the electrolyte level. This will eliminate the sulfate crystals that are building up on your battery plates, preventing them from recharging.

  Car Battery Is Dead How To Restart

  If your car battery is completely dead, you can jump-start it with another battery. Before jumping the cars, you need to make sure both batteries are matched and their voltages are equal. In this case, the other car must be running. Here are the steps for how to restart a car without a battery by jump-starting:

  1. Start your working car and let it run for about a minute. This will give the battery power to the starter, so it is not drained when you try to restart your dead battery.

  2. Start your other car; if you can't get it started, jump-start it with your current one.

  3. Position the two cars next to each other, facing in opposite directions, so the jumper cables can reach from one to the other.

  4. To make sure you don't shock yourself later (and maybe kill your car's electronics), unplug any accessories (radios, air conditioning) that are plugged into both cars.

  5. Start uncoiling the jumper cables from your good battery; it is best to coil them neatly on the ground near your feet.

  6. Open both hoods and locate the batteries. On most cars, you will see a black box with a bunch of wires coming out of it; that is the battery. ?Take one end of the red, insulated jumper cable and attach it to the positive terminal on your dead car's battery.

  7. Connect the other end of the red, insulated jumper cable to your good car's positive terminal. Next, attach the black, insulated jumper cable to your good car's negative terminal. And finally, connect this same black cable to an unpainted metal surface on your dead car-typically it will be near the dead battery or underneath a back seat.

  8. Now start the working car.

  Keep both cars running for about 15 minutes, or until you can get your dead battery up and running on its own.

  A Car Battery Is Dead And Won't Charge

  Check The Alternator

  If your car has been running fine for a while, and you go to drive it later, but the battery is dead and the alternator light is on, the alternator may be defective. Alternators are charged with a voltage regulator when driving. If you suspect an alternator issue, carefully inspect it and if you locate a damaged regulator, replace the alternator.

  If you have not had the battery disconnected for some time, check to make sure the battery cables are tight, clean, and properly attached. ?If not, tighten them with a wrench or pliers and check again.

  Clean The Battery Terminals

  Sometimes battery terminals can become dirty with oxidation or from corrosion. You can use a terminal cleaner to clean these, just spray it on and wipe it off with a clean, dry cloth. Be careful not to get the cleaner in the holes of the battery posts. Also, check to make sure your cables are attached to the right terminals. Clean the terminal and reattach it to the correct connection

  If there is some sign of damage or corrosion on the battery cables, you can replace them. Inspect your clamps and connections for signs of corrosion-you can clean these with sandpaper or a wire brush. And if you notice that the terminals themselves are damaged, you'll need to replace those

  Repair Faulty Cables

  You might have faulty wires or cables going to the starter if you do replace them. Connect a jumper wire from the good battery to the starter. If this does not recharge your battery, you may need to replace your starter.

  Conclusion

  No matter how well you care for it, your battery will eventually expire and you will need to replace it. Failing batteries generally exhibit apparent signs that alert you to the fact that they are on their way out. Slow-cranking on startup shows that the battery may not have enough power to start the engine, and an illuminated Battery Warning Light on the dashboard is a clear indication that it requires care. If your vehicle's electronics, such as remote locks or interior lights, suddenly cease working, it might be due to a failing or dead battery.
