6 volt battery charging

Is there any difference in charging a 6 volt battery, compared to a 12 volt battery?
I have the 6 volt battery for my 1951 Packard. Putting it on my 10 amp charger, it charges down to between 5 and 6 amps but doesn't seem to go any lower? With a 12 volt battery a battery charges down to between 2 and 3 amps.
Taking the caps off the 6 volt battery, I see little bubbles rising to the top. The battery doesn't seem warm from charging. Is the battery bad?

Thanks John
