10 'Yellow' Hearing Aid Batteries
To makes things easier on users, hearing aid manufacturers and battery makers have teamed up to create a simple to use colour compatibility system. All batteries in this section will fit a hearing aid requiring a yellow battery. This 1.4V battery measures 5.8mm in diameter and 3.6mm in height. It can also last up to 120 hours of use in ideal conditions.
10 (Yellow) hearing aid batteries use zinc air technology that uses oxygen from the atmosphere to pass through the small pores in the casing. This allows air to reach into the battery and cause a chemical reaction. The plastic seal on it protects the freshness of the battery as long as it’s stored at room temperature. Heat can shorten lifespan and it is also not recommended for refrigeration.
