Battery recommendations for 1500W inverter
Does anyone have recommendations for a 12V battery setup that can power a 1500W inverter? The background: my travel trailer is currently powered by two 6V golf cart batteries (Duracell SLIGC110 215...

I've measured the voltage at the battery terminals while running the microwave, and the voltage does indeed drop to 10.5V
Fascinating
A lot of responders did not read the OP's simple to understand post.
6 cells of GC220 battery cannot support that kind of load -- period
6 additional cells of GC220 will support the load for x amount of minutes, like for warming coffee or doing a baked potato.
12 additional cells will support the microwave for perhaps 20-30 mimutes continuous.
Does the OP have that much extra space? For the batteries?
Substituting a pair of high CCA AGM batteries like Full River or Deka would allow a microwave to run for perhaps ten minutes depending on battery temperature. 3 group 31 batteries would add another 5-7 minutes and this is due to Peukert it is not simply additive.
One thing about big battery banks is while 6 cells of wet may be sipping say 9 amperes of charge, 18 cells would be accepting 27 amperes.
18 cells of flooded battery can power DC hotel loads for many days at a time. In any event both max upgrades call for a minimum of 100 amperes bulk charge rate.
Beware of inflated generator ratings. Cheapos measure things while going down a steep hill with a 100 mph tail wind.
