How long do the batteries typically last?

The lifespan of batteries can vary depending on several factors. Typically, the longevity of batteries depends on their type and usage patterns. For disposable batteries, such as alkaline or zinc-carbon ones commonly used in everyday devices like remote controls, toys, or flashlights, they tend to last anywhere from several months to a couple of years, depending on the frequency and duration of use. Rechargeable batteries, on the other hand, can last for several hundred to a few thousand charge cycles before experiencing a noticeable decline in performance. However, it's important to note that the overall lifespan can be influenced by various factors such as temperature, storage conditions, device compatibility, and charging/discharging practices. It is always recommended to refer to specific product guidelines and instructions for optimal battery usage and maintenance.
