The Time Timer WASH requires 3 AA/1.5V batteries. We recommend using new high quality, single use alkaline batteries for best results and longevity.

The duration of the batteries will depend on various factors, including how often it is used and if music and alerts are used. With good batteries, your Time Timer WASH should last for over 9,000 activations in silent mode, or 5,500 activations if music and beep alerts are used.  

Your Time Timer WASH includes a low-battery indicator. You will see this icon light up when the batteries are over 70% through the life needed to operate the WASH. Your Time Timer WASH will last approximately 1,600 activations after the battery indicator light turns on.
