A gentle overcharge may top off all cells while those that are already full will not get damaged. A trickle charge will not only give better initial performance, but better performance all round.
It's the not knowing how to that's holding me back for now.

I have tried this with my Prius, a charge at a low rate (100mA) does not equallise the cells, it actually seems to make them more unequal...which supprised me, I think it is because the self discharge is so temperature dependant and the most full cells get warm and end up the lowest.
