Finding yourself with a dead battery in the middle of a trip can be one of the most frustrating experiences of your life, especially when you have no idea how to regenerate the battery or how to rebuild the car battery when the cell is dead.
So, if your car battery is running low and you don't know what to do, you've come to the right place because this article has everything covered, including answers to all of your battery-related questions.
How to Rebuild a Car Battery When the Cell is Dead
Rebuilding a battery is not a piece of cake if not followed with the correct steps. The people who don't know much about car batteries often get trap in extensive car showrooms when they can fix the car batteries themselves. But first, let's find out what happens when the car battery is running low or is dead
Your car takes a long time to start or "turn over" to get the engine going.
Your car starts and runs normally, but after a period of inactivity, it struggles to restart.
If your car is facing these symptoms, you need to rebuild the dead cell battery by following the below steps.
Bring 1/2 quart distilled water to a boil or about 150 degrees. Stir in 8 oz. (1/2 lb.) Epsom Salt (magnesium sulfate) to the boiled water. Continue to stir until the Epsom Salt is completely dissolved.
Clean the battery's exterior area with baking soda and clean water to avoid contamination. Make sure that the corrosion on the cable connections and battery terminals has been removed.
Remove the covers from the battery cells with care using a screwdriver. Remove the top surface of a sealed battery first, then the plastic caps and drill holes at impressions. Remove the debris from around the battery holes with a damp towel.
Remember not to fill the batteries with the solution using a metal funnel because the metal will undoubtedly react with the acids. Fill the batteries with the previously prepared solution. Replace the battery covers once they've been completely submerged.
Connect the battery terminals to the charger and charge it for 24 hours. This process can be repeated three times in a row to extend the battery's life.
You are done now the rebuilt battery is ready to use.
How to Rebuild a Battery Charger
If your charger refuses to charge your car battery, you can quickly repair the fuse in the mains plug as well as the fuse on the battery charger, as one of the fuses has most likely blown. Following are the steps for rebuilding a battery charger.
1) Check Battery Charger Output
Check to ensure that your battery charger is not producing any electricity. It is frequently the battery that will not charge, not the battery charger.
Connect the charger to the power supply. Set the charger to charging.
Check the battery charger with a voltmeter to see if it is producing electricity. Connect the red wire from the voltmeter to the metal clamp on the red cable from the battery charger. Connect the black wire from the voltmeter to the metal clamp on the black cable from the battery charger.
Take a look at the voltmeter display. If it reads slightly more than 12 volts, the charger is operational (so the issue is your battery). If there is no reading, the charger must be repaired (so check the fuses). You may occasionally get a reading of one or two volts. This is caused by electrical resistance and does not imply that your charger is generating electricity.
2) Replace Plug Fuse
Take the plug out of the mains socket. Using a screwdriver, unscrew the cover from the pin. Check that the three wires are securely connected to the terminals before replacing the fuse. If any of them are loose or disconnected, this explains why your charger is not working. Using a screwdriver, secure any loose connections.
Unplug the plug and remove the fuse. It can be difficult to remove using your fingers, so use a small flat-head screwdriver to pry it out.
Insert a new fuse into the fuse plug holder. Simply press it into position with your fingers. Ascertain that it has the same ampere rating as the fuse you removed.
Reinstall the plug's cover. Use a screwdriver to tighten.
Replace Battery Charger Fuse
On the battery charger, locate the fuse. It's usually on the front, hidden beneath a clear plastic cover. In the exact location, you'll usually find one or two spare fuses.
Use your fingers to open the fuse cover, or gently insert a screwdriver into the clip and pry it open. Take out the fuse from the holder.
In the fuse holder, insert a new fuse. It settles into position. Cover the fuse. Connect the plug to the power outlet and turn on the battery charger.
How do you regenerate a car battery?
The battery reconstitution process for a car battery takes approximately 24 hours. Larger items require more time (2 to 4 days). Regardless of battery size, the battery regeneration process breathes new life into the battery. The larger the battery, the easier it is and the better the results.
For regenerating a car battery, you will need the following items
plastic replacement plugs
Steps to Regenerate Car Battery
Allow the battery to cool for about an hour after you turn off your car.
Lift the hood and remove the battery – use a wrench to disconnect the negative cable first, then the positive cable.
Make sure your wrench does not come into contact with any other metal parts, or you may get a small electric shock.
Remove the battery with care once the cables have been disconnected
Remove the plastic caps from the battery cells' top. Underneath, you'll notice marks indicating where the cells have been sealed.
Make a hole in these marks with a power drill (cover your eyes with safety glasses).
Combine one part Epsom salt and three parts warm, distilled water.
Pour the solution into the cells, shake it around for a few seconds, and set it aside.
Connect the battery to the three-phase charger.
Connect the positive cable first, followed by the negative.
Turn on the charger and set the voltage to 12 volts. Allow 12 hours for charging.
Cover the drilled holes with plugs, reinstall the battery and connect it to the cables (positive first).
Maintaining a car is not an easy task especially when you have no idea about the situations that occur in your car's battery, like rebuilding a car battery when the cell is dead, rebuilding a battery charger, or regenerating the car's battery. But this article will help you to understand these situations in a precise and reliable way.
