Those Dallas "smart sockets" and the memory chips with internal batteries were a 10 year ticking time bomb. People who designed with them weren't thinking ahead 10 years to "what happens if the product is successful and starts to fail en masse ten years from now."
Customers don't like when their data collectors don't remember the date and are quoted a large price to effectively change a battery. Fortunately not my design nor the part of the company where I had any responsibility.
