A group 24 or 27 would last for a night or two depending on use. 2 6 volt batteries wired in series would give more.

1. 2 x grp 31 dual purpose batteries v.s. 2 x 6V GCs is a much fairer and more equal comparison based on more equal weight and Amphours.
2. The same goes to battery type. 12Vs are hybrid dual purpose, therefor giving a good compromise between low and high draws. GCs are deep cycle only and not designed for high draws.
It depends! What is the run time for a 1500W microwave with 2 x 6V GCs?
