Default Rechargable Cells/batteries for Lights

Hi,

Currently using a rather bog-standard cateye front light for commuting. It
requires two C/R14/Baby size cells. I'm currently usinf NiMh 2300mAh cells.
Despite the claims of global warming, the rather bitter cold here is having
a noticable effect on the performance of the cells (maybe up to 1/3
reduction). i hear that Cadmium cells suffer less from this effect (despite
their other shortfalls), does anybody know how true this is in a/this
practical sense?

Secondly, i suspect that the longer/faster i ride the colder the light
becomes (fact, i've experimented and the effect is noticable) thus effecting
the battery further and i presume this is to do with a) increased time in
the cold (obviously) and b)wind chill effect. Before i go to the bother of
creating some neoprene light sleeve to increase insulation does anyone know
if this is likely to have the slightest effect?

Any other ideas appreciated

Thanks
