ELI5: Why don't batteries charge instantly?

I never really thought about it but if there is an infinite amount of potential electricity flow from an outlet, why don't batteries charge instantly?

"if there is an infinite amount of potential electricity flow from an outlet"

There is not an infinite amount of potential electricity flow.

The amount of electricity flowing through a wire is limited by the wire. If you put too much electricity through a tiny wire, it can heat up and melt.
