Car battery maintenance is a common practice that most drivers need to perform regularly. Unfortunately, sometimes a dead cell may occur on the battery and prevent the car from running. This article will discuss the common causes of a dead cell and the steps you can take to fix the issue.
What is a Dead Cell?
A dead cell is a part of the car battery that has completely lost its ability to maintain a charge. This occurs when the lead-acid chemical that composes the battery is unable to keep a charge, causing the battery to fail. The most common cause of a dead cell is corrosion, rust, or other damage to the battery, which can be caused by leaking acid, old age, or prolonged exposure to extreme temperatures.
How to Diagnose a Dead Cell
Before attempting to fix a dead cell, you should first diagnose the battery to determine if a dead cell is the actual problem. The easiest way to do this is to use a multimeter and check the cell voltage. If the battery is unable to maintain a charge, then a dead cell is likely the cause. You can also inspect the battery cells for signs of corrosion or damage.
