Sulfation is when lead sulfate crystals form on the battery plates. This can happen if a battery isn’t charged for a long time or if it’s discharged too much. The sulfate crystals prevent the battery from being able to accept a charge. If left unchecked, sulfation will eventually destroy the battery. Most battery chargers have a setting that will desulfate a battery, typically indicated by the “SUL” setting on display. When you notice that your battery isn’t holding a charge as well as it once did, it’s crucial to use this setting on your battery charger, if it has one. Your battery’s lifespan and condition can be improved and extended by routinely desulfating it.
Can a sulfated battery be charged?
Sulfated batteries can be charged, but it’s important to do so carefully. A battery charger should be used at a low current rate (5 to 10 amps) until the gravity of the electrolyte increases. This will help to prevent further damage to the battery and prolong its life. It’s important to note that sulfated batteries require more frequent charging and maintenance than other batteries, so check them regularly. With proper care, a sulfated battery can provide years of reliable power.
Can you jump-start a sulfated battery?
A battery becomes sulfated when left inactive for long periods or when frequently discharged below 75 percent. During these conditions, lead sulfate crystals form on the battery’s plates, gradually growing larger and thicker. The result is a loss of power and capacity. While it’s possible to jump-start a sulfated battery, it’s not always effective. The lead sulfate crystals need to be broken up to restore power and capacity. This can only be done using a battery charger that delivers a high current pulse. When used correctly, a pulse charger can break up the lead sulfate crystals and revitalize a sulfated battery.
How long does it take to Desulfate a battery?
Desulfation is a process of removing lead sulfate from lead acid batteries. This build-up of lead sulfate occurs when the battery is not used for an extended period, causing the lead electrodes to corrode. Running current through the battery can desulfate it by oxidizing the lead sulfate and reducing it back to lead and sulfuric acid. The desulfation procedure can take anywhere from 48 hours to weeks to finish, depending on the size of the battery. During this period, the battery is also trickle-charged to continue reducing the amount of lead sulfur in the solution. Once the desulfation process is complete, the battery can hold a charge for longer and will be less likely to fail.
How do you fix a Sul battery?
One way to fix a sulfated battery is to give it an overcharge in the form of a regulated current. This will help to reverse the sulfation process and allow the battery to regain its full charge. It is important to ensure that the overcharge is properly regulated, as too much current can damage the battery. When giving the battery an overcharge, it is also important to monitor it carefully to ensure it does not overheat. If the battery becomes too hot, it may be necessary to stop the overcharge and let the battery cool down before continuing.
Will a sulfated battery start a car?
The simple answer to the question is no. A sulfated battery will not start a car. A battery suffering from sulfation has lost a significant amount of cranking power. It will likely only provide a small amount of power to the starter motor. The starter motor will not be able to turn the engine enough to start the car.
In some cases, the battery may provide enough power for the starter motor to turn the engine over but not enough to sustain it, causing the engine to stall. Suppose you suspect that your battery is sulfated. In that case, it is best to take it to a reputable mechanic or auto shop for testing and replacement.
How do I stop sulfation?
When a lead-acid battery is stored for long periods without being used, it can undergo a process called sulfation. Sulfation occurs when the lead sulfate crystals that normally form on the battery’s plates grow larger and heavier. This can eventually prevent the battery from holding a charge and, if left unchecked, can lead to permanent damage.
During storage, there are a few things you can do to avoid sulfation. Prior to anything else, make sure the battery is kept charged to at least 12.4 volts. Second, keep the battery in a space where the temperature doesn’t rise above 75°F (24°C). You can help ensure that your battery lasts for many years by complying to these simple and direct suggestions.
