How Long Does the Buick LaCrosse Battery Last?

[SanCarter]

The normal lifespan of a Buick LaCrosse battery varies between 1 to 8 years, largely depending on the vehicle's condition. If the vehicle's alternator charges properly and there are no electrical leaks or grounding issues, the battery can typically last more than 3 years. More details are as follows: 1. If you notice the battery isn't holding a charge, the starter is weak, or the headlights are significantly dimmer, remove the battery and charge it for 12-24 hours using a charger. If the issue persists and the mileage exceeds 50,000 KM without alternator problems, consider replacing the battery. 2. Some older batteries develop high internal resistance, appearing fully charged quickly but discharging rapidly. While a multimeter may show normal no-load voltage, it's essential to also measure the discharge current using a discharge tester. 3. During discharge, a voltage above 10V is normal; below 10V indicates possible battery cell failure, requiring replacement. The greater the voltage drop under load, the higher the internal resistance and the poorer the discharge performance.
