Recommend you take the CR2032 out when not using the calipers. Cheap/no name ones (atleast those sold 5-10 years ago) have a relatively high standby current, even when the LCD screen is off.
I just flip the coin cell around so it stays in the device but does not deplete (reverse polarity but in fact the contacts will not touch the battery poles so no harm).
Would you happen to know the current draws for the older and newer designs? I would like to check if mine are worth replacing (since I dutifully remove and store the battery in the designated holder in the case I can't rely on durability comparisons because it would depend on usage patterns).
I don't know the current draw of either. I don't know if newer designs are better, I only have one I bought around 10-15 years ago. For mine a bettery left in the calipers depletes within a few months, without use.
