well you did your part and the employee insisted on return you have no choice but to box it or maybe try this :
"try Soy with Soda mixed together with some foil so it seems like battery is coming out"

then retake photos and continue to say exactly this "upon picking it up for return when complying with their request the battery came out in and burned your hand "then send picture's as this have worked very well with our fellow friend here @justoutslder if he would like he may help you in this as you both have a very similar experience .

I did that pretty similarly and sent the photos. They came with a reply that it's returnable so I should return it and gave me instructions how to do it (their basic instructions, nothing special). Also stated preferably to use Amazon's carrier. Would it be wise to come with a reply to this about ADR and law violation and if not, then I may box them somehow. Though I don't know how, especially what if the dry ice evaporates too early before the guy picks up the parcel

Please describe the pictures you sent to them and how many?

I sent them 2 pics even if they asked for just one photo. Both of them from different angles and different position of the item. Everything was visible and pretty clear. Name and date printed on a paper. I'm thinking of boxing them, but idk, what are the chances that the box arrives and there's still dry ice in it? Plus the original delivery box was thrown away as I was doing the cleaning and spilled water on it and was destroyed. Does different box work tho? If using approximately same size
