Newbie..... Batteries?
I am desperate to be able to run a 1000 watt Microwave oven for a total of 15 minutes before needing to recharge the golf cart batteries. The inverter is 2000 Watts. How many 6 volt batteries will ...

CAtravler is dead on. His 100 amps is probably closer due to losses etc. With four batteries it will have no trouble providing solid power for 15 minutes.
Here is my rough calculations:
1100 Watts used to allow for some losses.
1100/12.5 volts DC = 88 amps DC. Divide that by four and you get 22 amps.
I often use a rough simple method.
Using AC take the 1000Watts and divide by 120 volts. You then get 8.3 amps. If you multiply the 8 amps times ten you get 80 amps of course and that is close to amount needed to run it via DC.
You could do this with two decent 6 volt batteries if rated properly.
