In a nutshell:

1. A much, much more powerful battery in the same if not smaller size than a 
single 6
volt. A compact 12 volt can provide 600-900 CCA for less than $60.
2. Longevity. The same 12 volt will outlast a pair of 6 volt batteries 2:1.
3. Limited maintenance of the new designs found in 12 volt batteries. Even if 
you don't
buy a maintenance free battery (no need for that), the modern 12 volt models 
require so
little attention that you might forget where the battery compartment is.
4. Fewer cable pieces and fewer battery connectors mean a more trouble free 
5. Lower cost: I think my last one was 875 CCA, 60 month battery for $50-60 at 
6. These days I have stopped buying those big, heavy marine batteries for my 
boat too. I
got tired of replacing those $125 behemoths every one or two seasons. Now the 
boat, and
the MGB, and the MGA all use the same battery model.
7. For some inexplicable reason the 12 volt battery terminals stay much cleaner 
and free
of corrosion than do the ones on the 6 volt batteries.

I'm sure there are even more reasons to make the conversion, but this should
