A common problem with car batteries is that the cells that hold the power in the battery don’t hold a charge. The problem usually occurs when a car sits unused for an extended period of time. How to recondition a car battery that won’t hold a charge?
The solution is very simple, but it requires that you remove the battery from the vehicle. This is a very difficult process, and you need to be extremely careful. The battery will have to be disconnected and the terminals removed so that it can be taken apart.
Once the battery is removed, the positive and negative terminals must be cleaned and inspected. If they are dirty or corroded, they should be replaced. Once this has been done, the terminal posts should be reattached to the battery.
This can only be done once the battery has been fully discharged.
Once the terminal posts are attached, the battery should be placed in a new car. If it won’t hold a charge, check the posts again for corrosion. If they still don’t work, it’s time to replace the battery.
Let’s Have A Look At How To Recondition A Car Battery That Won’t Hold A Charge:
Car batteries can be a real pain in the ass. I’ve had my fair share of experience with these, and after having spent so much time in the garage, I know exactly what it’s like to have a dead battery.
The solution is to find the battery in the car, and then start reconditioning it. This is actually one of the easiest things to do. It happens to all of us. You drive your car down the road and you realize the battery is dead. At first, you might panic thinking the worst – but the fact is you can still make it home. You’re going to need a few tools, but it’s a very simple process. I’m going to show you exactly how to do it in this post.
STEP 1 – Use a Test Strip to Check Your Battery:
First thing’s first, you need to check your battery. You can do this by using a test strip, or you can use the method I’ll show you.
Using a test strip is pretty easy, but it’s also very unreliable. They only work if you’re in a good electrical environment, and you’ll never get accurate readings if the weather is bad.
Using my method, on the other hand, will give you a better idea of how the battery is performing, and what you can expect when you get it back to life.
Make sure that your battery is good. There are two things you want to check – the voltage and the capacity. These will help you determine what kind of battery you have. If your battery is low on both of these items, then it’s time to replace it. To check the voltage, open up the hood of the vehicle and look for a sticker.
It should be between 2.6v. If you see something else, you need to get a new battery. Capacity is determined by the amount of power the battery can store. The best way to find out is by measuring the battery with a multimeter. I recommend the one below because it’s accurate and easy to use.
STEP 2 – Turn Your Car Off, and Remove The Battery:
Remove the battery from the car, turn off the car, and then remove the negative cable (the black one).
Next, disconnect the positive cable (the red one) from the battery. If you need to, you can use a screwdriver to get into the battery compartment to disconnect the cables.
If you can’t get into the battery compartment, you may have to disconnect the cables at the alternator.
STEP 3 – Unscrew the Battery’s Connector:
The next step is to unscrew the battery’s connector. This is really easy. All you need to do is push down on the side of the connector until it pops out.
STEP 4 – Connect the Battery:
Now that you know your battery is good, it’s time to connect it to your car. Open the battery compartment and make sure you remove any old terminals. Then, take the positive terminal and attach it to your car’s positive battery post. If your battery is older, you might not have a positive battery post, but you can still connect the negative terminal to the ground.
STEP 5 – Charging the Battery:
Now that you’ve connected your battery, it’s time to charge it. You’ll want to do this in three different steps. First, plug in the battery charger. You can usually find one on the back of your vehicle. Second, plug in the battery itself. Then, connect the charging cable to your battery charger. Finally, charge your battery for 4-6 hours. The first two steps are really all you need to charge the battery, but I like to follow up with the last step just to be sure.
STEP 6 – Connect the Test Strip:
Next, you’ll need to connect your test strip to the battery’s terminals. It doesn’t matter which end of the strip you use, but make sure that the positive side (the red one) is connected to the positive terminal.
STEP 7 – Insert Your Positive Cable into the Negative Cable:
Next, insert the positive cable into the negative cable. Again, it doesn’t matter which end you use, but make sure that the negative end is connected to the negative cable.
You can also do this by turning the positive cable, but it’s easier to just push it in.
STEP 8 – Disconnect the Battery:
Once you’re done charging the battery, it’s time to disconnect it from the vehicle. Once again, make sure you remove any old terminals first. Then, connect the negative terminal to the ground. Now that you have your battery charged, it’s time to test it out.
Plugin your battery charger and make sure that the voltage is between 3.6v. If it’s anything lower than this, your battery is dead and needs to be replaced. If everything is working, you’re ready to drive! If not, keep trying until you find the solution.
STEP 9 – Turn On Your Car:
Finally, turn on your car. Your test strip should read “charged” now.
