Battery questions

I have a Kuerig coffee maker that brews one cup at a time.

I would be running this with a 3000 watt inverter solely for the coffee maker. Trying to keep weight down I would like to keep it to 1 group 27 or 31 deep cycle. How long do you guys think the one battery would go if starting from fully charged?

Your Keurig is the problem - it draws WAY too much, so a single G27 or G31 won't run it at all without the inverter alarming almost immediately. My own 550 watt Cuisinart coffee maker runs well enough using a single G27 as source power without causing my 1000 watt PSW inverter to alarm provided the battery is fully charged but less than a full charge and the inverter will alarm. My 750 watt toaster causes the inverter to alarm regardless. Since we do this infrequently my solution is to load support my single G27 with my truck, as described earlier.
