Two [6V] batteries will not handle a coffee maker, you'll need 4. And you'll need a way to recharge those batteries. Without solar or a generator, that'll be a bit tough.
Yes, 4 6V GCs. Yikes, 260lbs of batteries to make some coffee!
Last week[as I posted on 2014-02-07], while in Quartzsite, I finally upgraded my van's system with a Magnum MMS-1012 inverter/charger. One more test of the Deka 8a24m 79AH AGM was to see how long it could be used in the morning. Keep in mind that this single 53lb battery is running two 12V compressor fridges 24/7 and had been running overnight. I ran a pot of coffee(~625W) for 6min, then ran the inverter MW at ~425W for a total of 20min to reheat coffee and heat food. These runs were spaced over 1:20. I did finally cause an inverter LVD at the at ~30min mark as I was making a second pot of coffee.
