Missing dead AirPods

Sorry, but as long as the case is not charged, you can not use Find My to locate it.

Which AirPods are you using?

Find your AirPods - Apple Support

Are your AirPods inside the case?

If they are not, you can get the case replaced by Apple and pair it to your AirPods again:

Apple Service, Repair and Replacement AirPods - Apple Support

If the Find My Network has been enabled before you lost your AirPods, they should show up on the map as soon as they can connect to this network, if they still have some battery life left.

Or as soon as they are being charged, in case somebody finds them.

• To locate your AirPods, you must turn on Find My on a paired device (such as your iPhone or Mac) before they’re lost. See Turn on the Find My network.
• You can turn on the Find My network to see the location of some AirPods models even when they’re out of range of your device. If the Find My network is turned off (or if your AirPods don’t support the Find My network), the Find My app shows the last time and place they were connected.
• If your AirPods are out of range or need to charge, you might see their last known location, “No location found,” or “Offline” in Find My. If they come back online, you get a notification on devices you paired with them.
