That’s definitely true. But I would definitely pay more for a scale with ultra long battery life.
I made the mistake of buying an off brand digital calliper and now like an idiot I find myself removing the battery when it’s not in use just to avoid damn thing running flat in one month thanks to its atrocious standby current which enables the display to turn on instantly when I move the slide (rendering the on/off entirely moot).
Next time I’ll just bite the bullet and buy a Mitutoyo.
Right. If your design requires 3.3V minimum then putting in a 3.3V battery and no boost converter is just dumb (or extremely user-hostile).
