Steps to Help You Repair Your Car Battery at Home with Epsom Salt

Fixing your car battery is not rocket science.

You don’t have to be an expert to know how to repair or increase your car battery’s lifespan. These tips and tricks should help get your car back on the road in no time.

The Equipment Needed

  • Battery charger

  • Flathead screwdriver

  • Neoprene Chemical Resistant

  • 1 Gallon of distilled water

  • Safety Goggles and Gloves

  • Voltmeter

  • Optimal Battery Post Cleaner

  • Plastic Bucket

  • 1lb Baking Soda

  • Plastic Funnel


The Process

1. Reconditioning Groundwork

The first step involves cleaning the corrosion in the battery terminals. This is one of the most crucial steps in reconditioning a car battery.

Ensure that you use a simple dirt cleaner to clean the terminals of your car battery. There are several dirt cleaning products in the market that you can use to clean your battery’s terminals.

You can also make a simple cleaning solution yourself by mixing one cup of water with two tablespoons of baking soda.

Ensure you mix the solution well until it transforms into a fine paste. Use a toothbrush to rub the paste on the car battery terminals.

For heavy corrosion, you may need to use steel wool. This is the very first step towards reconditioning a car battery. Also, don’t forget to use safety equipment like goggles and gloves.

2. Check the Battery Voltage.

Here’s where the voltage tester comes into play.

It’s the best device for checking the correct parameters of the power of your car battery. Again, there’s no rocket science needed here to check the voltage of your car battery.

Just connect the voltmeter to your battery’s terminals and check the readings.

If the reading is 12.6 Volts, then your battery is in good condition. If it’s more or less than that, then reconditioning is surely needed.

However, if the readings range between 10-12 Volts, you can easily restore it to full function. But, if the reading it less than 10 Volts, you’ll probably be wasting your time.

On rare occasions, the reading might reflect as zero. This likely means that your car battery went through a short circuit. On such occasions, it may be best to hire a professional for the job.

3. Take Out the Acid

Once you’ve known the battery’s voltage, it’s time you removed the old acid from the car battery.

You can use a flathead screw to reach and remove the battery caps. Remove all the caps and pour the old acid into a bucket or container near you. And in case any acid spills out, neutralize it using baking soda.

The acid inside a car battery is dangerous and very corrosive.

Therefore, ensure that you’re wearing protective gear during this step.

4. Return the Battery into Working Order

After cleansing the acid from the battery, the next process is to recondition it.

For that, you’ll have to refill it with electrolytes made of distilled water and Epsom salt.

This will enable the battery to charge very well and avoid sulfating. Pour this mix into your car battery’s cells.

5. Charge the Battery

This is the last stage of repairing your car battery.

Here’s where you check whether the reconditioning process worked or not. It’s best to leave the caps on since the electrolyte may overflow while charging.

Charge the battery for at least 24 hours or 36 hours.

Once you’ve charged the car battery, check the voltage using your voltmeter. Normal readings should be around 12.42 Volts. If yours reads something like that, then you should be set with an efficient car battery.

6 Ways to Extend the Lifespan of Your Car Battery.

Like a phone’s battery, a car battery degrades over time and becomes less efficient.

However, with proper care and maintenance, your car battery can serve you for a lot longer. These battery maintenance tips should help to boost the life of your car battery.

1. Avoid Driving Short Trips Often.

Every time you start your car, the battery takes a beating.

However, it’s always recharged when the engine is running for long enough, and the car is on the road.

For the car battery to fully recharge itself it needs a lot of running time. Therefore, if you’re only driving short distances, it becomes almost impossible for your battery to regain any power lost.

And repeating the same process daily can take a toll on your car battery.
If you think about it.

Repeating the process daily can impact your battery voltage up to the point where it won’t be able to start your car.

The best way to maintain your car’s battery power is to drive it frequently for longer periods. And if you’re not planning to use the car more often, you might have to invest in a car battery charger to maintain its correct voltage.

2. Tightly Fasten Your Car Battery.

Vibration can also reduce the lifespan of your car battery. You must use only the approved battery clamps to ensure that your battery is always held down properly.

Excessive vibration can also damage some of the internal components of your battery, creating short circuits. This, in turn, will reduce your car’s battery life.

Also, don’t over-tighten the battery clamp nuts.

You might end up damaging the battery as well. Tighten the nuts to the point where you feel resistance and stop. It should be just fine.

Don’t overlook this simple aspect of your car battery.

3. Minimize Power Used While the Engine Is Off.

Your car battery will be happiest when it’s close to 100% charge.

As a result, keeping your interior and headlights on while the engine isn’t running won’t do it much service. You must ensure that each time before you exit your car, all accessories are turned off to keep the battery in excellent condition.

4. Keep the Battery Clean.

Remember, the top of your car battery must always be kept clean, dry, and not have dirt or grime.

A dirty car battery can discharge across the grime, creating a mild short circuit that will eventually flatten the battery.

Keeping the terminals clean from buildup and corrosion is also a great way of extending your car battery’s lifespan. Ensure that all of the car battery terminals are always clean and dry before you start your engine.

5. Try to Minimize Heat Exposure.

Car batteries always work harder to start the engine during cold weather than in hot weather.

However, the cold is hardly always the problem. It’s always as a result of the damage your car battery sustained from the heat of the summer period.

Extreme heat can be hard on car batteries since it increases the water evaporation rate from the cells.

Even sealed batteries cannot escape this, and the shortcomings often result in a weaker battery. The best way forward is to try and minimize extreme temperature changes subjected to your car battery.

6. Don’t Leave the Car Unused for Too Long.

As you might have already noticed, your lead-acid car battery must always remain charged.

Regardless of your car battery brand, remember that all lead-acid batteries naturally lose their charge over time. Therefore, it mustn’t stay idle for too long.

Prevention is the Best Solution.

If you’re looking to know how to fix your car battery, the first thing to always keep in mind is that preventing damage to your car battery is always better than repairing it later.

The best way to deal with battery sulfation it to prevent it. You must ensure that your battery charging system functions correctly and maintains a full charge to increase your battery life-span.

Wrapping it up

It cannot be emphasized enough that car batteries are your automobile’s arteries. Without it, you stand no chance of starting your car. Hence, you must always care for it and maintain it as required by its manufacturer. And the steps mentioned above are an excellent place to start.
