Is it normal for a car battery to fail after one and a half years?

It is not normal for a car battery to fail after one and a half years. If you usually neglect maintenance or use it incorrectly, its lifespan will definitely be reduced. Here are the correct methods for using a car battery: Charge frequently: The battery should be used and charged regularly to keep it in a saturated state, which will extend its service life. Do not wait until the battery is depleted before charging it, as this will shorten its lifespan by one-third. Also, avoid overcharging. If the charger is used for a long time, its components will inevitably age, leading to leakage. Prevent overcharging: Overcharging the battery generates a large amount of gas that erodes the plates, accelerating the shedding of active material from the plates and shortening the battery's lifespan. Overcharging also accelerates water loss, leading to the drying up of the electrolyte, an increase in battery temperature, thermal runaway, plate expansion, and casing deformation.
As a veteran driver with over 20 years of experience, I think it's somewhat abnormal for a car battery to fail in just one and a half years. Generally, automotive batteries last three to five years. If you're in extremely cold northern regions or hot southern areas, harsh weather can accelerate battery aging, but one and a half years is still unusually quick. I once encountered a similar situation and found that short-distance driving was the culprit—commuting only about ten minutes daily meant the battery never fully charged before stopping, leading to significant long-term wear. Electrical issues, like power leakage from aftermarket audio systems, can also shorten battery life. I recommend having the technician check the voltage and charging status during your next maintenance. Opt for a reputable brand—like the German-brand battery I replaced, which has lasted four years and still going strong. Also, take longer drives occasionally to ensure proper charging and avoid prolonged vehicle inactivity. These small habits can save you a lot of trouble and money.
