Hearing Aid batteries come in four sizes and are color coded to help you easily identify the right size. The batteries are air-activated, which means they do not begin working until the colored tab is removed and air is able to enter the battery cell. Remove and discard the tab only when you are ready to use the battery. There is no need to place the tab back on the battery.
- Size 10 batteries have a yellow tab
- Size 13 batteries have an orange tab
- Size 312 batteries have a brown tab
- Size 675 batteries have a blue tab
