Car batteries typically last between 3 to 5 years on average, though this can vary depending on several factors such as climate, driving habits, battery type, and maintenance practices

• In cooler climates, batteries may last closer to 5 years or even longer, while in hot climates, the lifespan often shortens to around 3 years due to accelerated chemical degradation caused by heat

• Standard lead-acid batteries usually last 3 to 5 years, AGM (Absorbent Glass Mat) and EFB (Enhanced Flooded Battery) types tend to last 4 to 7 years, and lithium-ion batteries can last up to 10 years or more under ideal conditions

• Factors such as leaving electrical components on when the engine is off, frequent short trips, corrosion on battery terminals, and improper jump-starting can reduce battery life

• Proper care, such as keeping the battery fully charged, protecting it from extreme temperatures, regular cleaning of terminals, and driving regularly, can help extend its life

In some cases, with excellent care and favorable conditions, car batteries have been known to last 10 years or longer, but this is uncommon

. In summary, expect your car battery to last about 3 to 5 years under typical conditions, with potential variation based on environment, battery type, and usage. Regular testing after 3 years is recommended to avoid unexpected failures
