When your car battery dies, it can be a frustrating and stressful experience, especially if you’re stranded in the middle of nowhere. In a desperate attempt to get back on the road, some people might turn to unconventional solutions, like putting an aspirin in the car battery. But does this miracle cure really work? In this article, we’ll delve into the science behind this hack and separate fact from fiction.
The Origins Of The Aspirin Hack
The idea of using aspirin to revive a dead car battery has been circulating online forums and social media platforms for years. It’s unclear who originally came up with this hack, but it’s likely that it started as a myth or an old wives’ tale. Some claim that the aspirin trick was popularized by resourceful mechanics or DIY enthusiasts, while others believe it’s just a baseless rumor.
Despite its murky origins, the aspirin hack has gained significant traction, with many people swearing by its effectiveness. But before we dive into the details, let’s take a step back and understand how car batteries work.
How Car Batteries Work
A typical car battery is a type of lead-acid battery, which consists of several key components:
- Positive and negative plates made of lead dioxide and pure lead, respectively
- Sulfuric acid electrolyte solution
- Separators that prevent the plates from touching
When a car battery is fully charged, the lead plates are fully oxidized, and the sulfuric acid solution is at its highest concentration. As the battery discharges, the lead plates begin to sulfate, and the acid solution becomes diluted. This process is reversible, meaning that recharging the battery can restore its original state.
The Problem With Dead Batteries
A dead car battery is typically caused by one of two things: sulfation or acid stratification.
Sulfation
Sulfation occurs when the lead plates are exposed to air, causing them to form a layer of lead sulfate. This layer acts as an insulator, preventing the battery from holding a charge. Sulfation can be caused by:
- Deep discharging
- High temperatures
- Aging batteries
Acid Stratification
Acid stratification happens when the sulfuric acid solution becomes unevenly distributed within the battery. This can cause the acid to become more concentrated at the bottom of the battery, leading to a buildup of sulfate crystals on the plates. Acid stratification is often caused by:
- Inadequate maintenance
- Infrequent charging
- Incorrect charging techniques
Can Aspirin Really Help?
Now that we understand the basics of car batteries and the common causes of death, let’s examine whether aspirin can actually revive a dead battery.
Theoretically, aspirin contains acetylsalicylic acid, which is a type of organic acid. Some proponents of the aspirin hack claim that this acid can help to:
But here’s the thing: aspirin is not a substitute for proper charging or maintenance. At best, the aspirin hack might provide a temporary fix, but it’s not a sustainable solution. In fact, adding aspirin to a dead battery can cause more harm than good.
The Risks Of Using Aspirin
Introducing aspirin into a car battery can have several unwanted consequences:
Contamination And Corrosion
Aspirin can contaminate the sulfuric acid solution, causing corrosion on the lead plates and other metal components. This can lead to permanent damage and reduce the battery’s lifespan.
Inconsistent PH Levels
The acetylsalicylic acid in aspirin can alter the pH levels of the battery’s electrolyte solution. This can affect the battery’s chemistry, making it more prone to sulfation and acid stratification.
Fire Hazards
In rare cases, the aspirin hack can increase the risk of a battery fire. When aspirin reacts with the sulfuric acid solution, it can produce hydrogen gas, which is highly flammable.
What To Do Instead
If your car battery is dead, it’s essential to identify the root cause of the problem and address it accordingly. Here are some recommended steps:
Charge The Battery
Use a high-quality battery charger to recharge the battery. Make sure to follow the manufacturer’s instructions and safety guidelines.
Check The Electrolyte Levels
If the battery is old or has been neglected, the electrolyte levels might be low. Check the levels and top them off with distilled water as needed.
Perform A Battery Load Test
Conduct a load test to determine the battery’s capacity and identify any underlying issues.
Consider Replacing The Battery
If the battery is old or has been damaged beyond repair, it might be time to replace it with a new one.
Conclusion
While the aspirin hack might seem like a quick fix, it’s not a reliable or sustainable solution for reviving a dead car battery. Instead, focus on proper maintenance, regular charging, and addressing the underlying causes of battery death. Remember, it’s always better to err on the side of caution and consult a professional mechanic if you’re unsure about what to do.
Don’t take a chance with your car’s battery – prioritize safety and reliability over unproven hacks.
Can Aspirin Really Revive A Dead Car Battery?
Aspirin cannot revive a dead car battery. The myth that aspirin can revive a dead car battery likely originated from the fact that aspirin contains acetylsalicylic acid, which can be used to clean corrosion from the terminals of a car battery. However, this does not mean that aspirin can revitalize a dead battery.
It is important to note that a dead car battery requires a proper recharge or replacement, not a DIY fix with aspirin or any other household item. If your car battery is dead, it is best to have it checked and serviced by a professional mechanic or a car electrician.
How Does Aspirin Clean Corrosion From Car Battery Terminals?
Aspirin can be used to clean corrosion from car battery terminals by breaking down the corrosion and allowing it to be easily removed. To do this, crush an aspirin tablet into a fine powder and mix it with water to form a paste. Apply the paste to the corroded area and let it sit for about 30 minutes. Then, rinse the area with water and dry it with a clean cloth.
It is essential to note that while aspirin can clean corrosion from car battery terminals, it does not address the underlying issue that caused the corrosion in the first place. It is also important to wear protective gloves and safety goggles when working with car batteries and electrical systems to avoid injury.
What Causes Car Battery Corrosion?
Car battery corrosion is typically caused by acid spills, electrolyte leakage, or moisture accumulation on the terminals. It can also be caused by poor maintenance, such as not cleaning the terminals regularly or not ensuring the terminals are securely tightened.
Regular cleaning and maintenance of the car battery terminals can help prevent corrosion. It is also important to check the battery water level regularly and top it off as needed. Additionally, ensuring the battery is properly secured in its mounting bracket can help prevent vibration, which can cause corrosion.
How Do I Know If My Car Battery Is Dead?
There are several signs that indicate a dead car battery. If your car won’t start, or the engine cranks slowly, it may be a sign that the battery is dead. Other signs include dim or flickering headlights, slow or weak accessory performance, and a clicking sound when you try to start the engine.
It is also possible to check the battery voltage using a multimeter. A fully charged car battery should have a voltage reading of around 12.6 volts. If the voltage reading is below 12.4 volts, the battery may be dead or dying.
Can I Recharge A Dead Car Battery?
In some cases, a dead car battery can be recharged. However, this is not always possible, and the success of recharging a dead battery depends on the type of battery and the reason it died. If the battery died due to a deep discharge, it may be possible to recharge it. However, if the battery died due to internal damage or corrosion, it may not be possible to recharge it.
It is also important to note that recharging a dead car battery requires specialized equipment and knowledge. It is best to have a professional mechanic or a car electrician recharge the battery to ensure it is done safely and correctly.
How Do I Prevent My Car Battery From Dying?
