Digi-Key p/n 439-1016-ND is a (non-rechargable) Tadiran 3.6V AA, 2400mAh,
17.6g.  The D cells offer even better energy density, albeit at $18 each.
Since this would really be an emergency/contingency measure, I don't think
non-rechargable batteries would be a problem.  Plus, the shelf life is
great.
