Bad battery. The inverter with no load should not be a heavy current draw, it should be trivial. But the battery craps out. It's either a non-battery at this point or, as Karl suggests, you have a damaged connection at the terminal.

Disconnect the inverter and the voltage at the battery reads 12.x volts again. I don't think it's a bad battery.
