The size and style of battery is dependent on which musical potty seat you purchased. Your instruction manual and/or packaging will provide you with the type of battery you need to purchase. DO NOT mix old and new batteries and DO NOT mix alkaline, standard (carbon zinc), or rechargeable (nickel-cadmium) batteries. Always remove the batteries when the potty stored for long periods of time. Note: If the sound module is not working, please check to ensure the batteries were installed correctly. Installing batteries backwards may cause irreparable harm to the electronics.
