How Long Can a Car Battery Last Before Replacement?

[LeCharlotte]

Generally, the lifespan of a car battery is around 3 years. Here is some relevant information about car batteries: Working Principle: A car battery, also known as a storage battery, is a type of battery that converts chemical energy into electrical energy. Typically, when people refer to a car battery, they mean a lead-acid battery. This type of battery is primarily made of lead and its oxides, with a sulfuric acid solution as the electrolyte. Maintenance Tips: Avoid storing the battery in a discharged state. A discharged state refers to when the battery is not recharged promptly after use, which can lead to sulfation. Sulfation occurs when lead sulfate crystals form on the electrode plates, blocking the ion channels and resulting in insufficient charging and reduced battery capacity. The longer the battery remains in a discharged state, the more severe the damage. When the battery is not in use, it should be charged once a month to extend its lifespan.
