Why do batteries have to alternate when you put them in?

I'm fumbling with my camera in the dark here forgetting which slots go positive up. Why can't they all just go positive up or something?

well they could still be in series, it's just easier/cheaper for them to manufacture it this way

Hmm... I guess that's true, they could still have them connect in series inside the camera..

That is an interesting thought.... But you're right, it would raise costs.

Yes, technically they could stillb be in series...but any engineer who put two batteries in series like that would need to be fired immediately.

Why? Why would it make a difference what direction the batteries are put in as long as the wiring is correct inside? Something like that just makes it easier for the end user.
 
In standard battery compartments, the current path actually makes a zig-zag pattern. Imagine if you took a line of batteries that were all tied together, and then folded it. That's what happens. To place them all the same direction, you would have to have a contact, and then a wire go to the other end of the compartment for each battery. In the case with hinged doors that have contacts on then, you would need extra contacts for these wires instead of just metal springs.

The added cost, complexity, and loss of reliability just isn't worth it.

Because if you made them all go in the same way, you would have to run a wire from the end of battery 1 to the top of battery 2 (to keep them in series). If you alternate them you can just have them share a plate of metal to make the connection because + and - from battery 1 and 2 are on the same sides.

Indeed.
