In most facilities, batteries in towel dispensers last for one to two years. However, some high-volume buildings may have to replace them once or twice a year. Make a battery replacement schedule so janitors know when and how often dispensers will need new batteries. Regardless, replacement batteries are inexpensive and have minimal impact on facility budgets.

Manufacturers are also proactive about fears over battery failure. New products on the market can operate as mechanical or sensor-operated so users can still pull a towel if the sensor isn't functioning properly.
