It usually says that on things you buy that require batteries.

Don't mix different brands or fresh/used batteries in the same device.
Different brands could/will have different stored energy capacities and different impedances. If you run the mixed battery pack down close to zero power, then it is likely that at least one battery will be driven close to zero voltage or even a reverse voltage.
This is bad because the chemistry of that super dead battery changes & may release gases & leak electrolyte gunk all over the insides of your device.

It isn't bad to mix brands of batteries. It's bad to mix new batteries with old batteries, because the power pull on the newer batteries will be disproportionate, which could damage them and possibly the device. They're telling you that as a CYA.

Different brands are okay so long as they are of the same type of construction. It is only bad to mix different types of cells such as general purpose, heavy duty, alkaline, ni-cad, etc. or as the first poster said, to mix like cells with different amounts of charge. The reason for this is because when one runs down the others will continue to push a current through the discharged cell, causing it to charge in reverse, which will cause it to overheat and possibly leak. And if it leaks it can damage your equipment.

different brands are likely to have different internal dimensions of electrodes and electrolyte.
while they may be very similar, any tiny difference will be exaggerated when you mix.
the difference will cause 1 brand of cell to deliver more than its fair share of the power, thus running out before the other, you then hit the "dont mix old and new" problem

Different brands have slightly different capacities and abilities. In rare circumstances this may throw extra load on to one of the batteries causing it to heat up and burn. It can melt and throw its internal chemicals all over your valuable electronic device.

The thing that you buy might be broken if you mix the brand with the same size.
