The lifespan of 3 AAA batteries in a flashlight depends on various factors such as the capacity of the batteries, the power consumption of the flashlight, and the usage pattern. On average, standard alkaline AAA batteries have a capacity of around 1000-1200 mAh each. If the flashlight consumes 100 mA of current, the batteries could last approximately 10-12 hours. However, if the flashlight has a higher power consumption, the batteries may last for a shorter period.
