Hi All
So, as per subject. This is for some solar lights that have 250mAh NiMH
1.2V AA cells, but would 2500mAh cells work too?

Assuming they are the same physical size as the 250mAh cells and fit,
then in principle they should give you light for longer, appropriate
for early winter evenings and long nights.

Yes.

But the converse is that
they'll take longer to recharge, inappropriate for short dull winter
days.

No, you should get the same amount of charge added
and so get the same result even on short dull winter days.

Very crude simple chargers may limit the amount of
charge the cell gets to avoid overcharging so while
it will still work with the higher capacity calls, you won't
see any advantage when using higher capacity cells.
