Why does removing a battery and replacing the same battery (in a wireless mouse for example) work?

Basically as stated above. When my mouse's battery is presumably dead, I just take it out and put it right back in. Why does this work?

The contacts on the battery and your device can develop a layer of corrosion as they're exposed to oxygen. This layer does not conduct well. By replacing it you're scraping the contacts clean allowing better conductivity. When the batteries get low, this can make the difference between a usable amount of current and not.
