How many years can a car battery last before replacement?

[TheoMarie]

The car battery typically needs replacement every 2-3 years. Below is an introduction about car batteries: 1. Introduction: A car battery is a type of battery, also known as a storage battery. 2. Working Principle: Its working principle involves converting chemical energy into electrical energy. The commonly referred car battery is a lead-acid battery, which mainly uses lead and its oxides as electrodes and sulfuric acid solution as the electrolyte. 3. Maintenance Methods: Avoid storing the battery in a discharged state. A discharged state means the battery was not recharged promptly after use. In this state, sulfation is likely to occur, where lead sulfate crystals adhere to the plates, blocking ion channels and leading to insufficient charging and reduced battery capacity. The longer the battery remains idle in a discharged state, the more severe the damage becomes.
