What is an exponential?
@Hanno Becker @Steve Huntsman just a note: the group of invertible elements in a Banach algebra has natural structure of manifold modeled on the underlying Banach space, and I know Serge Lang's Foundamentals of Differential Geometry as the reference for Banach Manifolds. There the exponential map is associated to any spray on a Banach manifold. |

@Hugo Chapdelaine: does not your question concern Lie groups? |

On closed totally disconnected subgroups of connected real Lie groups
and what if we consider a topological group which is not locally euclidean? |

@Hugo Capdelaine but in such a case even $G$ would be totally disconnected, while you assume $G$ connected |

On closed totally disconnected subgroups of connected real Lie groups
@Hugo Chapdelaine: as outlined in my answer, when $H$ is a closed subgroup of the Lie Group $G$, the Cartan--Von Neumann theorem implies that $H$ is an embedded Lie group. Aside it is clear, from the definition, that a topological manifold is totally disconnected if and only if it is 0-dimensional. |
