How To Fix Any Dead Car Battery Back To Life Again? 

 September 29, 2021

As a car owner, you know that your battery is an essential part of the vehicle. If it dies, you are stranded wherever you happen to be. How do I bring my car battery back to life? How can I make sure this doesn't happen again? How do I fix a dead battery in my car? These questions and more will be answered in this informative blog post!

Basic requirements:

Reconditioning your dead battery will require assembling some ingredients that you might not find in the home. Safety goggles, rubber gloves and an apron are necessary to protect yourself from any harmful chemical reactions during this process, while baking soda and distilled water help remove sulphuric acid corrosion for better conductivity. Always be careful when using anything electrical!

Clean Battery Terminals:

It is best to start by cleaning the battery terminals because they have a lot of buildups. To clean them, you can use an old toothbrush and baking soda. It would be best to scrub them with a toothbrush until all the buildup is gone and then rinse them with water.

Check Battery's Fluid Levels

You should also check your battery's fluid levels because if the levels are low, it may be losing power, and this could cause your battery to go dead. Here's how you do this: remove the vent caps on top of the cells (if you have sealed batteries) or loosen the metal terminal covers on top of open-cell batteries. Add plain water per the markings inside. Test your battery with a voltmeter and make sure that the voltage is at least 12.

Check Voltage

Next, you should start by checking your battery voltage. You can do this with a digital voltmeter or an analog meter with at least three volts for accuracy. Make sure it is read on the DC scale and not AC (alternating current). If your car's alternator is working properly, then powering up the engine will be enough to charge your battery back to life, but if it isn't, you may need to jump-start it from another vehicle to get things going again!

Clean Battery Acid

If the corrosion is too much to handle, you can use baking soda and distilled water to solution three parts water to one part baking soda. This will help rid your battery acid from any sulphuric buildups that are on it for better conductivity!

Electrical Testers

You should also invest in an electrical tester because they'll be able to tell you whether or not your car's alternator is working properly. It does this by testing out how many volts are coming off the battery when running and then comparing them with readings taken after the engine has been turned off but before disconnecting power cables. You want these numbers as close together as possible if something isn't right, so take note of them so that you know what needs to be fixed.

Clean Cells of the Battery

Once you have finished cleaning the battery terminals, you should also clean out any cells of your battery. This can be done with water and a paintbrush or by spraying them off until they are free from corrosion deposits.

Recondition Battery

After you have finished cleaning the battery and all of its cells, it is time to recondition your battery. This can be done by taking a solution of distilled water and baking soda in a ratio of three parts water to one part baking soda. You then need to add this mixture into each cell (or use it for spraying) while connecting them with wires on top. Once they are connected, charge it up so that corrosion starts eating away at any acid buildups.

Recharge Battery

You will know when your car's battery has been successfully revived because an electric tester should read 12 volts or more after charging! If you're unsure about how voltage works or what some terms mean, don't worry! Everything will be explained in detail below!

Battery Test

You should also invest in a battery test so that you can see if your car's alternator is working properly. It does this by testing out how many volts are coming off the battery when running and then comparing them with readings taken after the engine has been turned off but before disconnecting power cables. You want these numbers as close together as possible if something isn't right, so take note of them so that you know what needs to be fixed!

Many reasons can cause a car battery to die. Regardless of the reason, drivers need to know how to change and fix their dead batteries so they don’t get stranded on the side of the road or in an unsafe area. If you have had your battery die recently, watch this video as we show you step by step instructions from start to finish on how to recondition your battery.
