Hi,

So many times i read in product manuals "dont mix old and new
batteries", can someone tell me why?

it can cause the depleted cells to become "charged" in the reverse direction

(if you don't understand how that could happen i'd suggest studying basic
electronics, in particular kirchoff's loop law.

that can make them leak, or worse...

I have a wireless mouse and keyboard here and strapped for cash. Got
some nice energizer batteries and i want to put one in the mouse and
one in the keyboard. Each take two batteries each, any harm in mixing
them up?

could leave an ugly stain. may damage thje insode of the devices too.

maybe you can do without the mouse?
