This experience is fairly common. hat most people fail to appreciate is that our Chinese friends in particular fit cheap batteries of often dubious quality that may already be quite old at the factory and the item may then spend several months or longer in transit or on the store shelves before getting to the customer. Many instruments in particular do not have proper on/off switches that isolate the supply but merely the display and the device may still draw a good percentage of the full on current. These facts coupled with the fairly rapid self discharge of cheaper battery types explain dead cells or short initial life when the instrument is purchased.
I too have found that cells bought on e-bay seem to last over a year in most of my calipers, scales etc

The "free" batteries suck. Out of 3 scales, only one set was good. The others were dead. Replaced with fresh store bought and they've been fine for well over a year.
