• There are four different battery sizes: 10, 13, 312, and 675. Manufacturers use an industry-standard color code to identify the battery size. Different battery sizes are used to power different types of devices. You can find which type of battery your device requires by referring to your hearing device's manufacturer's manual.
    • Battery life is determined by the type and amplification of your hearing aid, as well as the hours you wear it. Because this varies from person to person, we suggest you consult your hearing professional so they can properly diagnose the expected battery duration in accordance with your specific lifestyle.

    • Store your batteries at room temperature. Avoid extreme temperatures, heat will shorten the life of the batteries and refrigeration is not recommended. Avoid carrying batteries in your purse or pocket because metal objects such as keys or coins can short out batteries.

      - Do not leave batteries in the hearing instruments if you do not use them over a long period of time, they can potentially leak and ruin your hearing device.

      - Replacing the tab when the battery is not in use will not extend the life of the battery.

      • Keep out of the reach of children
      • Make sure batteries are secure in the device
      • Do not leave batteries out where they can be mistaken for medicine or pills
      • Do not put batteries near the mouth
