A 3V CR2032 battery is already inserted in the scale, and you need only pull the red tab. Factory the scale is set to "kg". Already can start weighing. Works flawlessly and always displays the same weight. What I like not so good, therefore only 4 stars, when viewing the weight of the background of the display is not illuminated, characterized at least for me, sometimes not so easy to read. On my old scales the background was blue illuminated by the displayed weight was more noticeable
I would still buy the balance at any time and can only recommend this further.
