Vehicle batteries have it rough. Extremes of temperature, humidity, and constant charging and discharging begin to wear a battery down from the very first time it is called upon to work. The problem is, batteries tend to work OK or not at all. Very seldom are you given fair warning that total failure is imminent. Vehicle batteries typically last no more than 3-5 years under normal operating conditions. After that, their ability to accept and hold a charge is compromised.
The next time you are in for service, ask us to perform a “load test” to determine the health of your vehicle’s charging system & battery.
