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 ...

Thanks everyone but it sounds like a bunch of "educated guesses".
Isn't there some precise math?
People's guesses are based on education and experience. This is all you are going to get here.
There is a precise math - Peukert spreadsheets. But you don't have a precise data, so we are back to guesses again. MW current is unknown - unless you really measured those watts, or Peukert coefficient for your batteries. 1000W oven draws around 150A DC at high setting.
My educated guess - assuming Peukert 1.4 for average flooded, and DC current with inverter 150A, gives 420A Peukert corrected current for 2 GC. Meaning, you will be down to 50% after 15 minutes run. Sounds like possible - in theory - but your 2 GC are not going to like 150A.
Get 4.
Btw, I don't understand a "desperate" need for MW without shore power, unless this is something that is really, really difficult to do on a stove top. Very few tasks are, baby food heating maybe.
