Does anyone know how to change out the batteries in the wireless headsets in a 2002 Chrysler Town and Country Ltd ? Thanks

 

I believe these are the over-the-top infra-red headsets?

If so, very simple. Hold the headset the normal way up. On one of the two sides has a small ridge, this is the point to get your finger and pull it swiftly downwards which should get you to the battery compartment.
