I want to store a battery powered device long term (decades) as a reference article, it will never be switched on or charged again. The problem is that it contains a small LiPo battery that will be very hard to remove.
Is there likely to be any significant risk I need to worry about? Once depleted will the battery be relatively inert?
Brilliant, many thanks. With all the old phones in my cupboards I’d hoped this was the answer, but it’s good to get a second opinion.
