Direct connection of two batteries

[kimmy510]

If i connect the positive terminal of a 5 volt battery to positive terminal of 10 volt battery and the negative terminals of both batteries are also connected without using any resistance or any other components in between what will happen to the two batteries?. Will the one with higher voltage discharge and the one with lower voltage charge?

Please don't do that. It could result in a fire or other bad things happening.

Batteries are low output impedance voltage sources, and large currents could flow if unequal batteries were connected in parallel.
