Any reason I cannot just use inexpensive NiMH batteries?

I replaced my nicd original with 2500mAh nimh. They charge and runtime the same. My solar lights run all night and shut off at sunrise in the Summer but only light for about 2 hours in the Winter.
same experience here, I upgraded the Westinghouse HiMH AA to Eneloop AA and I put them in fully charged. They worked all night for a few nights in the winter, but then the solar panel was not able to fully charge the AA cell and they were very weak towards the morning. I think the issues is not the cell, but the small area and low efficiency of the solar panel.
