Is your dead battery useful anymore?

Dead batteries are so much dreaded, and for a good reason – they can be so inconveniencing and annoying at the same time.

No one wants to be helpless when the power they so much need is suddenly not available, and now they have to seek other alternatives which may as well not work as expected. You never want to be stranded for hours just because your car won’t start and there is no one to help.

To avoid such situations, it would be best if you acquired lead acid battery repair skills. Even though having such skills may not be so useful when you have an emergency, you should save a significant amount of cash and time by using them.

Besides, it’s always interesting when you get to learn new skills and use them to make life easier. Other than just using lead acid battery reconditioning skills to ensure that you never run out of power, you could also decide to commercialize the skills.

The most amazing thing about learning how to recondition a lead-acid car battery is that it’s not complicated and won’t need a lot of cash.

How batteries die

Before you go ahead and learn how to repair dead lead-acid batteries, it would be so important to get to know the science behind a failing lead acid battery. When a battery is functioning as it should, it creates power from lead plates immersed in sulfuric acid. The reaction that produces the power is the same that produces a substance referred to as lead sulfate.

When a healthy lead-acid battery is being charged, the substance is usually converted into lead and sulfuric acid, which is not the case with a non-functioning battery. An old non-functioning battery will have the lead sulfate form a solid substance instead of breaking down into lead and sulfuric acid.

Lead acid battery sulfation

For someone who has had some information about dead lead-acid batteries before, the world sulfation should not be new. It’s the word given to the process that ‘kills’ car batteries, after the lead sulfate crystalizes and coats the lead plates. Once that has happened, and the battery’s performance is crippled, we can say that the battery is dead.

Sulfation typically happens when a lead acid battery is not charged sufficiently to provide the amount of power required. This is quite common with city cars as the motor doesn’t provide enough power to charge the battery as it should. The main reason behind that is that city cars don’t travel fast for long distances and fast enough to generate enough power to keep the battery charged.

Sulfation also affects other machines as well, such as wheelchairs and even golf carts if they are not charged for the recommended number of hours. For anyone wondering how many hours they should charge a lead acid battery, keep in mind that less than 14 hours is not healthy. Such batteries require a minimum of 14 hours to get to the saturation point.

How does sulfation affect your battery?

A sulfated battery is not necessarily a dead battery, even though some sulfated batteries won’t work at all. Sulfation is, however, the reason why a battery’s capacity goes down, recharging times become longer, and the working temperature of the battery becomes high. A sulfated battery is also highly prone to corrosive damage.

Restoring a lead acid battery: Is it possible?

Sulfation does not mean that your battery’s lifespan has come to an end. It is possible to rejuvenate a lead-acid car battery, using a special charger. The charger used for such a purpose produces a high current that is sent down the battery, to break down the crystalline lead sulfate. Once the lead sulfate has been broken down to lead and sulfuric acid, your battery’s charging capacity will have been restored.

This method is, however, not always a good idea, as the high current can damage the battery, and in some cases, lead to grid corrosion. The best thing to do when repairing a lead-acid battery is reconditioning.

Reconditioning a lead-acid battery

The process of reconditioning a lead acid battery is not as complicated as you may think. Here are the steps you should follow:

1. Get the battery and remove the protective caps.

2. If distilled water levels are low, add enough, and recharge the battery without reinstalling the protective caps.

3. If the problem is not solved, it’s time for a more advanced solution. Get an acid pack to replace the one in the battery, then add some fresh distilled water. Remember to get rid of the ‘old’ water before you begin the process. After you are done, charge the battery for not less than 14 hours to get it working well.

When adding or replacing the acid, remember to wear gloves and goggles for your protection. You also have to get a voltmeter to measure charge levels when reconditioning the battery for best results.


To be able to recondition a lead acid battery successfully, the electric cells and plates have to be sound and functional, failure to which your battery may never revive. In addition, the battery will not have a 100% capacity even after reconditioning, but the power you will have back should be enough for use in a car.

That way, you can prolong the life of your lead-acid car battery, as well as save some cash. The best thing is that the process is not complicated, and you don’t stand to lose anything by trying.
