7 Dead Car Battery Tricks

Dead Car Battery Tricks

A car battery is essential to any vehicle, providing the necessary electrical power to start the engine and operate various electrical systems. Like any other equipment, a car battery has a finite lifespan and can be considered dead when it no longer functions optimally or fails to perform its intended duties. But there are several tricks you can try to get your vehicle up and running again. Consider these simple solutions before calling for roadside assistance or spending money on a tow truck.

Tapping or Turning the Battery Terminals

Tapping or turning the battery terminals is a famous trick to revive a dead car battery. This simple technique can sometimes provide a temporary solution when your vehicle fails to start due to a drained battery. To perform this method, you will need a pair of pliers or a wrench to loosen and tighten the connectors on the battery terminals. Now locate your battery’s positive (+) and negative (-) terminals, typically marked with red and black covers, respectively.

To tap the terminals, strike each terminal with the handle of a screwdriver or another small metal object. This action helps dislodge any loose connections that may have formed due to corrosion. Tapping can also help redistribute electrical charge within the battery cells, potentially allowing it to regain enough power to start your car. Alternatively, you can try turning the terminals instead.

Use a Portable Jump Starter

A portable jump starter is a compact and lightweight device that can provide the necessary power to start your vehicle when the battery dies.

How to use a portable jump starter? Here is:

  • Connect it to your car’s battery following the manufacturer’s instructions.
  • Attach the positive (red) clamp to the positive terminal of your car’s battery and the negative (black) clamp to a grounded metal surface in your engine bay.
  • Once properly connected, turn on the jump starter and attempt to start your car as usual.
  • The powerful burst of energy from the jump starter will give your battery enough juice to get going again.

Use Jumper Cables

Jumper cables can be the lifeline that every car owner should have in their vehicle’s emergency kit. With the proper technique and some help from another vehicle, you can quickly jumpstart your dead car battery and get back on the road soon. Here is what you can do:

  1. Locate the positive terminal on the dead battery, usually marked with a + sign. Attach one end of the red cable clamp to this positive terminal securely, ensuring it is tightly connected.
  2. Next, locate the positive terminal on the working battery and attach the other end of the red cable clamp to it. Both clamps must be securely fastened to their respective terminals to ensure a successful jumpstarting process. Once you’ve successfully attached one end of the red cable to each battery terminal, connect one black cable clamp.
  3. Once identified, take one end of the black cable and securely attach it to the working battery’s negative terminal. This connection will act as an earth or ground connection during jumpstarting for safety reasons.
  4. Now, take the other end of the black cable and securely attach it to an unpainted metal surface on the car with the dead battery, such as a bolt or bracket. This helps ground the circuit and prevents any sparks or electrical mishaps.
  5. Start the car and let it run for approximately 10 minutes.

Smear Petroleum Jelly On The Battery

When your car battery is exposed to air and moisture, the sulfuric acid inside can react with these elements, leading to corrosion on the terminals. This buildup of corrosion can hinder the flow of electricity between the battery and other electrical components, resulting in a weakened or dead battery.

Applying a thin layer of petroleum jelly onto the terminals creates a barrier that helps prevent air and moisture from reaching them. This protective coating significantly reduces the chances of corrosion forming and extends the lifespan of your car battery.

Use Soda To Clean The Corrosion

Dead Car Battery Tricks

Yes, soda is an effective and affordable way to tackle battery corrosion. The carbonation in soda helps break down the acid buildup on the terminals and connectors. All you need to do is pour a small amount of soda directly onto the corroded areas of your battery.

The enthusiasm will work its magic by eating away at the acid residue, making removing it easier with a wire brush or cloth. Not only does soda make cleaning corrosion a breeze, but it also provides a bonus – preventing future buildup!

Trick The Car Computer By Accelerating

By using this simple yet effective technique, you can accelerate the charging process of your dead car battery and trick the car computer into thinking everything is just fine. No need to wait hours or call for roadside assistance – take matters into your own hands with this handy trick.

This method involves revving up your engine while someone else tries to start the vehicle. Doing so increases the alternator’s output, which helps charge the battery faster than it would under normal circumstances.

Drop Two Aspirin Tablets Into Each Battery Cell

Did you know a couple of aspirin tablets can revive a dead car battery? Yes, it’s true! This simple trick involves dropping two aspirin tablets into each battery cell, which can help jumpstart the chemical reactions within the battery and bring it back to life. While it may sound like magic, some science is behind this method.

A car battery usually dies due to accumulated lead sulfate crystals on the battery plates. These crystals prevent the flow of electrons necessary for powering your vehicle. Aspirin contains acetylsalicylic acid, which has been found to dissolve these crystals. By dropping two aspirin tablets into each cell of your dead car battery, you create an acidic solution that helps break down the lead sulfate buildup.

Remember, this method carries an element of danger and should only be attempted cautiously and under proper safety measures such as wearing a pair of protective goggles.

Use The Epsom Salt Trick

Epsom salt, also known as magnesium sulfate, is a readily available household item that can work wonders when reviving dead batteries. The trick lies in its ability to dissolve and remove the sulfation buildup on the battery plates, which often causes the loss of charge. To

What Causes Dead Car Battery

Understanding the common causes of a dead car battery can help you take preventive measures and avoid getting stranded on the road. Several factors contribute to this issue, ranging from simple human error to more complex electrical problems.

Vehicle Age And Usage Patterns

A car battery’s lifespan typically ranges from 3 to 5 years, depending on various factors. Frequent short trips without ample time for the storm to recharge can accelerate its deterioration. Similarly, vehicles left unused for extended periods can drain the battery due to natural self-discharge. Aging batteries are also prone to failure as their capacity diminishes over time.

Extreme Weather Conditions

Harsh weather extremes can take a toll on your car’s battery health. In cold climates, extremely low temperatures slow down chemical reactions inside the battery, making it harder to generate sufficient power. On the other hand, high temperatures cause fluid evaporation and accelerate internal corrosion within the battery, leading to premature failure.

Corroded Battery Terminals

Over time, corrosion can build up on your car battery terminals due to exposure to moisture and air. This corrosive buildup prevents a solid electrical connection between the terminals and the cables, resulting in poor energy transmission. As a result, your battery may fail to recharge properly or drain completely.

Leaving Lights On

Forgetting off your headlights or interior lights is a common cause of dead car batteries. It may seem like a minor oversight, but the constant drain on your battery can quickly deplete its charge and leave you stranded. Always double-check that all lights are switched off before leaving your vehicle unattended.

Parasitic Drains

Parasitic drains mean unnecessary power consumption by specific electrical components even when the car is unused. These components can include features like clocks, alarms, entertainment systems, or diagnostic modules that require a small amount of electricity to function continuously.

How do they drain your battery?

While individually consuming minimal power, collectively, these components can significantly drain your car battery over time. This happens because they continue drawing energy from the battery even when the vehicle is switched off or parked for an extended period.
