Most automatic soap dispensers use alkaline batteries, which have a typical lifespan of around two years. But the true battery life will depend on several factors, including the type of dispenser, the frequency of use, and the ambient temperature.
For example, dispensers used more often or kept in warmer environments will generally have shorter battery life. In contrast, those used less frequently or kept in cooler environments typically have longer battery life.
It’s key to follow the manufacturer’s recommendations for care and maintenance to maximize battery life. With proper care and regular battery replacement, an automatic soap dispenser can provide years of trouble-free operation.
