The water might break down under fairly weak fields because K = 80 is
a very high number for a simple natural substance. What this means is
that the bound electrons are on very weak "springs" and have large
deflections (K = 80) so that a moderate field might break the springs
and free the electron for conduction.
If the battery remains connected, the E field is still there,
exacerbated by local ionizations, and able to do more ionization
rather than herding ions where they can't do any harm.
What is "thinly insulated"?
