Car batteries can sometimes die unexpectedly, leaving you with a stranded vehicle. While it’s always best to take your car to a professional mechanic to have the battery replaced, sometimes a dead sealed car battery can be revived, saving you some money in the process.
Sealed car batteries are called “maintenance-free” because they are designed to last a long time without needing any water or acid added to them. However, over time, these batteries can lose their charge and become completely dead.
If you have a dead sealed car battery, don’t worry – there are several steps you can take to revive it. In this article, we’ll discuss some of the best methods for rejuvenating a dead sealed car battery and getting your vehicle back on the road.
Reviving A Dead Sealed Car Battery: How To Do It
Step 1: Check the Battery
Before attempting to revive a dead sealed car battery, it’s important to check the battery thoroughly to ensure it is indeed dead and not just discharged. Use a multimeter to check the voltage and if it reads below 11.5 volts, it’s likely the battery is dead.
Step 2: Clean the Battery
If the battery is dead, removing any corrosion on the battery terminals is essential to revive it. Use a wire brush to remove any corrosion and clean the terminals with baking soda and water to neutralize any acid residue.
Step 3: Reviving the Battery
One method to revive a dead sealed car battery is a process called equalization, which involves slowly charging the battery with low voltage over an extended period of time. This can be done with a desulfating charger or a DIY charger using a car battery, a voltage regulator, and a light bulb. Allow the battery to charge for several hours or overnight, monitoring the voltage regularly.
Step 4: Test the Battery
Once the battery has been charged, it’s crucial to test it again with a multimeter to ensure it’s working correctly. If the voltage has increased and maintains a stable charge, it’s likely the battery has been revived successfully.
- Remember, reviving a dead sealed car battery is not always guaranteed to work and it’s important to prioritize safety at all times when working with car batteries.
- Always wear protective gear, use caution with tools and chemicals, and dispose of any old batteries properly.
Understanding Sealed Car Batteries
What is a Sealed Car Battery?
A sealed car battery is a type of lead-acid battery that is designed to be maintenance-free. Unlike traditional flooded batteries, which require routine checks and occasional water additions, sealed batteries are completely sealed and prevent the risk of acid spills.
Sealed car batteries can be further divided into two categories: Absorbed Glass Mat (AGM) batteries and Gel batteries. AGM batteries use a fiberglass mat to absorb the electrolyte solution, while Gel batteries use a silica gel to suspend the electrolyte.
Advantages of Sealed Car Batteries
One of the main advantages of sealed car batteries is their maintenance-free design. This eliminates the need for routine checks and water additions, making them a convenient option for those who do not want to deal with the hassle of maintaining their battery.
Sealed batteries also tend to have a longer lifespan than traditional flooded batteries due to their sealed design. This design prevents the electrolyte from evaporating, which can lead to premature battery failure.
Additionally, sealed batteries are typically safer to use than flooded batteries, as there is no risk of acid spills or leaks. They also have a lower self-discharge rate, meaning that they can be stored for longer periods of time without losing their charge.
Disadvantages of Sealed Car Batteries
Despite their advantages, sealed car batteries do have some drawbacks. One of the main disadvantages is their higher cost compared to traditional flooded batteries. This cost can be attributed to their advanced technology and longer lifespan.
Sealed batteries also tend to be less tolerant of overcharging and overheating, which can lead to battery damage or failure. It is important to use a charger specifically designed for sealed batteries to avoid these issues.
Finally, when a sealed car battery does fail, it can be more difficult to revive than a traditional flooded battery. Some methods of reviving a dead battery, such as adding distilled water, may damage the battery and render it unusable.
Common Causes Of Sealed Car Battery Failure
One of the most common causes of sealed car battery failure is overcharging. When a battery is overcharged, it causes the electrolyte to heat up and evaporate. This leads to damage to the battery cells and ultimately reduces the battery’s lifespan.
On the other hand, if a battery is not charged sufficiently, it can lead to sulfation. Sulfation occurs when the lead plates in the battery are not fully charged, and acid builds up on them. This can reduce the battery’s overall capacity and lead to a shorter lifespan.
3. Exposure to Extreme Temperatures
Sealed car batteries are designed to function within a specific temperature range. When a battery is exposed to excessively high or low temperatures, it can cause damage to the battery’s internal components. This can lead to reduced performance and a shorter lifespan.
4. Physical Damage
If a sealed car battery is dropped or exposed to physical damage, it can lead to internal damage to the battery cells. This can cause leaks and ultimately lead to battery failure.
5. Neglect and Lack of Maintenance
Sealed car batteries require regular maintenance to ensure optimal performance. Neglecting to maintain the battery or failing to replace it when necessary can lead to a shorter lifespan and reduced performance.
To prevent sealed car battery failure, ensure that the battery is properly charged and maintained. Avoid exposing the battery to extreme temperatures or physical damage. If you notice any signs of battery failure, such as difficulty starting the vehicle, replace the battery promptly to avoid further damage.
Reviving A Dead Sealed Car Battery: Step By Step Guide
Step 1: Safety precautions
Before attempting to revive a dead sealed car battery, ensure that you have taken all the necessary safety precautions. Wear gloves and goggles to protect yourself from battery acid. Work in a well-ventilated area to avoid inhaling any harmful fumes.
Step 2: Clean the battery terminals
Using a wire brush, clean the battery terminals on both sides. Ensure that there is no corrosion, rust, or dirt on the terminals, as this might prevent the battery from charging properly. You can use a mixture of baking soda and water to clean stubborn grime.
Step 3: Check the water level
For a sealed car battery, there is no need to add water to it. If you have an older battery that requires water, ensure that the water level is between the minimum and maximum marks.
Step 4: Charge the battery
Using a battery charger, charge the battery for several hours. If the battery is extremely dead, it might take up to 24 hours to charge fully. Ensure that the charger is set to the appropriate voltage for your battery.
Step 5: Test the battery
After the battery has charged, use a voltmeter to test its voltage. A fully charged car battery should read approximately 12.6 volts. If the battery is still dead, try the charging process again or consider replacing it.
Step 6: Maintenance
To avoid a dead car battery in the future, ensure that you keep up with regular maintenance. Check the battery terminals for corrosion regularly and keep the battery charged by driving your car frequently.
By following these steps, you can revive a dead sealed car battery and save money on a replacement. With proper maintenance, your battery should last for several years.
