that seems… unlikely, just because of the labour cost to change the batteries compared to a DC power supply and plugging the shelves in

    They have to change whats on shelves and distances between items all the time. So changing batteries isnt all that uncommon.They also are pretty power effecient since the displays are e-ink Edit: also we have a box of batteries in the back. If we notice a whole rail isnt displaying properly we can go grab a new one and have it switched out in like 2 minutes.
