How to Recondition Batteries

Did you know that there is a way to bring back to life dead batteries so you won’t need to purchase a replacement? You can do this via a battery regenerator or otherwise known as a battery reconditioner, desulphator, or pulse conditioning device.

Also, I will show you how to properly clean off the things in our batteries that are causing the problems.

Through these, we can effectively restore the capacities of our lead-acid batteries, which would mean we would be able to extend their lifespan. Additionally, you must know, that the process of reconditioning is not the same as recharging. When you recharge a battery, you aim to restore the charge for just a limited amount of time. In reconditioning, you will bring the battery back to its full capacity.
So let’s get down to business.

Battery Reconditioning: How does it work?

Batteries that go uncharged for an extended period of time slowly become sulfated. This happens when lead-sulphur deposits then prop up on the lead plates inside the battery. As a result of this, the battery can’t fully charge to its initial capacity. This is where regenerators/reconditioners come in. They send through the battery high-frequency pulses of electricity that flake off and eliminate any built up sulfate. Keep reading and I will show you the regeneration process through these pulses in greater detail.

Through the application of higher voltages, you can dissolve the crystallized lead sulfate layer back into a solution. This running of a high voltage into a battery, however, would normally cause it to rapidly heat. This then giving in to the potential of an explosion via thermal runaway. That’s why a battery reconditioner uses just enough short pulses of high voltages to reverse the crystallization process of the sulfate.

Battery Reconditioning Guide: Why?

You can do this for economical reason or even open up a battery reconditioning business.
The stockpile of dead batteries in your garage could make for worthy candidates. You potentially could restore all types of batteries from the deep cycle/gel type to the usual car battery using these methods. While not all batteries are the same, the principles are the same.

Battery Reconditioning Guide

The first thing to do in the process of reconditioning your lead acid type battery that has sulfated due to old age or extended use would be an inspection of any kind of defects. These defects could hinder you from fully reconditioning your battery. They could have burnt connectors or melted plastic housing. Any physical signs that point as to why the battery does not work could prevent you from restoring it in the end.

However, if no signs appear, then using this method of battery reconditioning could potentially bring back your battery to life.

Warning: Be extremely careful when handling any chemicals. These batteries contain potentially harmful acids. They can cause irritation or worse. Proper clothing and protective gear are advised as safety when dealing with such chemicals. You have been warned. 

For this method, you will need lots of water and baking soda. You will start by washing thoroughly your battery. For any oils or stuck dirt, you may use a soft brush. For a really dirty battery, you can use soap to clean it. If you use baking soda, it will render any reacting battery acid harmless.

Through the use of a screwdriver, you will need to pry the covers off your battery cell. As a safety precaution from the battery acid, you ought to wear old clothing or an apron. Acid is known to quickly chew through clothing.

So set the covers aside. You can use a small vacuum to suck out any large specks of dirt. Remember to also not let any dirt get into the cells of the battery. Wipe the area around the holes of your cells with a damp paper towel.

Next, you must fill the cells with distilled water to a level just right above the plates. Be sure to use distilled water. Using tap water may corrode your battery. And car batteries usually have a plastic cover over the plates. You must fill your water up to above the plastic cover top. Using a small water bottle can help avoid any messy or shaky pouring of water. Do it slowly and prevent the water from overflowing.

Now, all you have to do is to recharge your battery. You can do so with a professional radiant energy battery desulfator or DIY Battery Restorer.

Battery Reconditioning Guide: Using Chemicals

Step 1. Cleaning terminals

You will need to get rid of any corrosion or dirt of your terminals.

Step 2. Checking voltage

If your battery does not read 12 volts, then you have a problem with a cell.

Step 3. Testing cells.

Test each cell of your battery if it is weak or bad. Each cell must get a reading of at least 2 volts.

Step 4. Battery load test.

For this step, you are to test the load of your battery. Be mindful when doing so.

Step 5. Hydrometer test.

This is akin to the battery load test. You are going to use the hydrometer for step.

Step 6. Adding chemicals.

If it is determined that the battery is available for reconditioning, we now add some battery reconditioning chemicals.

The battery will need to be charged for about 24 hours.

Battery Reconditioning Guide: Epsom Salt Method

The first thing you will need to do is determine if the battery would respond to the reconditioning proces. The voltmeter must show 12 volts. The sweet pocket would be around 10 and 12 volts but anywhere below, it could be a waste of time.

Heat a half quart of distilled water to 150 degrees Fahrenheit. Additionally, dissolve 7 or 8 ounces of Epsom salts in the water.

Remove the cell caps of your battery. If they were sealed, find the shadows plugs that would cover the cells of your battery. These you must drill through.

Then, drain the fluid out of the battery. Furthermore, use a plastic funnel to pour enough of your Epsom salt solution. This is so that you can have each cell of the battery properly filled.

Insert the plastic plugs into the drill holes. Replace the battery caps and then shake your battery so that your Epsom salts are well spread out.
