How Long Does a Buick LaCrosse Battery Typically Last?
2 Answers
The normal service life ranges from 1 to 8 years, largely depending on the vehicle's usage conditions. Under circumstances where the vehicle's alternator charges normally and there are no electrical leakage or grounding issues, the battery can generally last over 3 years. Below is additional information: Noticeably Dim Headlights: If the battery seems unable to hold a charge or the starter is weak, and the headlights are significantly dimmer, the battery should be removed and charged for 12-24 hours using a charger. If the issue persists and the mileage exceeds 50,000 kilometers with no alternator faults, consider replacing the battery. Measurement: Some batteries develop high internal resistance after prolonged use, becoming fully charged quickly but discharging rapidly. Such batteries may show normal no-load voltage when tested with a multimeter. Therefore, it's essential not only to measure the no-load voltage but also to check the discharge current using a discharge tester. A discharge voltage not dropping below 10V is normal; if it falls below 10V, the battery may be failing and requires replacement. The more the voltage drops under load, the greater the battery's internal resistance and the poorer its discharge performance.
I've been driving the LaCrosse for five years and have gone through two battery replacements. Generally, the original battery lasts three to four years, but its actual lifespan depends on how you use it. For someone like me who frequently takes short trips—just a few kilometers to and from work—the battery doesn't get fully charged and dies in less than three years. If you drive long distances more often, the battery charges sufficiently and can last over four years. You also need to pay attention to the environment. High summer temperatures cause the battery's electrolyte to evaporate quickly, accelerating aging, while in northern winters, sub-zero temperatures make starting difficult and drain the battery faster. It's recommended to check the voltage at least once a year. If you notice the engine struggling to start or hear a hissing sound when turning the key, it might be a sign the battery is failing, and you should replace it promptly—don't wait until you're stranded on the road, which can be a huge hassle. Turning off the AC and headlights before parking and shutting off the engine can also help extend the battery's life. Overall, under normal use, you should consider replacing the battery after three years. Don't skimp on this expense—safety comes first.
