Traditionally batteries are paired at opposite ends, but this isn't always the case. Do you know the reason why?
Mystery Hour Question
Batteries have a positive and negative side, and usually a remote controller has one battery facing each way. However, I've found a remote which works with batteries facing the same way. Why is this?

Answer: When batteries are placed parallel to each other, they use less than their full power, but last longer. If they face opposite ends, then they're in a series. This allows the battery to put out its full wattage.
