Why do batteries have to face the opposite direction in order for the device to actually work?

So the current goes from negative to positive to negative to positive so it can actually flow.

Haha sorry that was probably wrong, I’m just guessing.

They don’t always face opposite ways, it just depends on how the device is wired.

I’ve got a few electronic doo-dads where they do orient all in the same direction.

The thing is, the device maker is trying to get the batteries to all line up positive-to-negative in a line.

When a device needs two rows of batteries, the “line” then makes a 180-degree turnaround. Hence, one row orients one way, and the other in the opposite direction.

The manufacturer just needs to get the circuit lined up right. Opposite orientation simplifies that process (and build cost), but it’s not a requirement. They could (and sometimes do) route the wire the long way from the positive terminal of one row to the negative of the next, allowing the batteries of both rows to orient in the same direction.

I have no exact idea about this question. Im so sorry buddy.
