The lifespan of batteries in a torch (flashlight) can vary significantly based on factors such as the type of batteries used, the brightness level of the torch, and its usage frequency. Alkaline batteries typically last anywhere from 2 to 20 hours, while rechargeable lithium-ion batteries can last several hours to days on a single charge, depending on the torch's settings. Using lower brightness settings generally extends battery life. Regularly checking and replacing batteries as needed will ensure optimal performance.
