Battery Reconditioning Epsom Salt
An easy, step-by-step guide to recondition dead batteries with epsom salt at home.
Battery reconditioning with Epsom salt is a cost-efficient method of extending and reviving the natural life of your lead-acid battery. Like me, I am quite stingy when it comes to paying a hefty price for brand new items when I can still squeeze some juice from my old stuff.
There are several other additives you can use in making your electrolyte solution. However, I am to focus on Epsom salt today in my sharing. Above all things, you need to secure your safety before doing the whole process at home. Battery solutions are made from acidic liquids, so you need to wear your gloves and goggles for
I have here some of the things you need to know about battery reconditioning Epsom salt. Just continue reading up to the last portion of my article.
Benefits of Epsom Salt Lead Acid Battery Reconditioning
You can experience a few benefits from reconditioning your old batteries. Below are some of the essential benefits you can have.
Huge Cost Savings
Reconditioning your car batteries allows you to avoid shelling out huge money for a brand new cell. The standard 12V car battery costs around $50 to $120, while the expensive brands are between $90 to $200. By reconditioning, you can save around 25 to 50 percent of the retail cost.
Earn a few bucks
How many of your neighbors have old car batteries that are not damaged but are still functional? Say, you have 10 of them. A brand new battery would cost around $100, but if you recondition their batteries and charge them about $20 to $50. You will earn around $200 to $500 for all 10 of them. That is already good money.
By learning the concepts of battery reconditioning Epsom salt, you can start your own business and earn a decent profit.
There are millions of car owners all over the United States. If all of them would replace their old car cells, then that is around 1million lead-acid battery waste for disposal. To help minimize this waste, reconditioning your 12V car cells will be a good practice.
Tips and Warnings
I always prioritize safety among all things, precisely when dealing with chemicals. Please bear in mind that battery solutions are acidic and they contain traces of lead metal. These chemicals are harmful to our health and the environment.
Car battery solutions are mostly made up of sulfuric acid, which is highly corrosive and generates some fumes which you must not inhale. To protect yourself, wear the proper safety attire, that is, goggles, gloves, and apron.
When doing the reconditioning process, make sure you are in a well-ventilated area with an available supply of water. Likewise, avoid directly pouring out the old electrolyte solution as it might splatter everywhere and in your clothes.
How to Recondition a Old Battery with Epsom Salt
We are now in the reconditioning proper, and you have to prepare the required materials for this process. Here are the materials and tools you need to make beforehand.
Materials and Tools
- Epsom salt
- Baking soda
- Distilled water
- An old or new toothbrush
- Steel wool or sandpaper (optional)
- Battery load tester
- Battery reconditioning charger
- Flathead screwdriver
STEP 1Wear your protective safety attire – gloves, apron, and goggles.
STEP 2Remove the battery from your car and place it on your working table.
STEP 3Remove the corrosion in the battery terminals. Prepare a baking soda (2 parts) and distilled water solution (1 part). The resulting solution is sticky and paste-like.
STEP 4Get your toothbrush and dip it into the baking soda solution. Then brush the battery terminals to remove the corrosion.
STEP 5WIf the corrosion is hard to remove, use steel wool or sandpaper.
STEP 6After, remove the battery caps using a flat head screw and place it in one container to avoid losing them.
STEP 7Gently tilt the battery and pour the old electrolyte solution in your bucket.
STEP 8Depending on the volume of the battery solution, you can pour 1 lb of baking soda into the bucket to neutralize the acid.
STEP 9You can prepare another baking soda (1 part) and distilled water solution (1 part). Use your funnel, and pour some volume in each cell. Return and close back all battery caps, and shake the battery for 30 seconds to 1 minute. In this way, the lead sulfate solids in the plates are dissolved. You can do this process twice. Remove the battery caps, and pour out the solution into the same bucket.
STEP 10Preparation of the Epsom salt battery solution
- Heat 1/2quart of distilled water to 66 degrees Celsius. We do this to ensure all salts are dissolved later while mixing.
- Dissolve 7 to 8 ounce of Epsom salt into the warm distilled water and stir until completely dissolved.
You can repeat the process if not all cells in the battery are filled with the new electrolyte solution.
STEP 11Use your funnel, and pour the prepared Epsom salt solution into each cell of your car battery.
STEP 12Return and secure the battery caps back into your car battery.
STEP 13Connect your battery charger to the 12V car battery, and put it in slow charge mode 12V/2amp. Let it charge for 12 to 24 hours.
STEP 14After charging, measure the voltage of the battery using a voltmeter. A battery that is in full capacity and good condition will have a reading of 12.4V to 12.43V.
STEP 15If the battery did not reach that voltage reading, you need to discharge the battery and recharge it again adequately.
STEP 16Place the battery in a load test. You can buy a battery load tester from any hardware store. It comes at an affordable price only.
Epsom Salt Battery Myth
I still hear some rumors about the Epsom salt battery myth, and if it works for reconditioning. Here, I have a few ideas on why it works in bringing back the life of your car battery.
Epsom salt has the chemical name Magnesium sulfate. This salt has many applications, and its food grade brand is used for cooking. During the reconditioning process, one thing that must be remedied is the sulfation in the plates.
Sulfation happens when the solid lead sulfate builds around the battery plates inside. Epsom salt or Magnesium sulfate solution is capable of softening these solid salts.
Magnesium sulfate and lead sulfate undergoes a single replacement reaction. Magnesium metal is more reactive than lead, so it is capable of replacing it in the plates. Take note; Magnesium sulfate is highly soluble in water. With this, lead metal is gradually restored and removed around the plates.
Overall, the Epsom salt solution helps in the desulfation process and serves as a good conductor for current.
Frequently Asked Questions
I also included a few FAQs regarding the topic for more insights.
What is a suitable voltage for charging car batteries?
You can charge your car batteries with voltages higher than 12V – e.g., 15V. However, you need to have close monitoring to avoid overcharging, and it must not reach 100%full capacity.
Meanwhile, if you plan to leave it for charging, then the suitable float voltage is 13.6V to 13.8V.
After starting the engine, how long do you think until the battery recharges?
A general answer for this is around 8 to 99 seconds after starting the engine.
When do you add water to your battery? After or Before charging?
Typically, you need to add the water before charging the battery. During the charging process, bubbles are created, which helps mix water and battery acid.
At what voltage level do you consider your battery to empty?
If the voltage reading of your battery is below 10V, then you consider it empty or fully discharged.
How much is Epsom salt required to rebuild a battery?
You have to make a mixture of 4 ounces of Epsom salt and 4 cups of water. Now you have to stir both the ingredients so that the water becomes clear and transparent. Now, you can use this solution in your battery. Thus, as an answer to the question, a single battery will require 4 ounces of Epsom salt.
Can I put aspirin in the battery to work?
Yes, you may use aspirin to make your battery work. But, make sure to put only two aspirin tablets in the solution. Also, keep in mind that using aspirin in the battery to make it work temporarily can reduce the life of the cell in the long run.
How to desulfate the battery?
For this, you need to have a battery charger that comes with the advanced desulfate mode. Now, let it set in charge, and you can observe the battery getting charged at its highest voltage. Thereafter it will get to its disulfate mode.
Thank you for reading through the whole section of my article. I hope I was able to share good ideas about the topic. There are so many things to gain from reconditioning batteries.
