VCCBAT range is 1.2V to 3.0V. So, 1.8V is fine (although not exactly in line with a note in the datasheet). It states:

If you do not use the design security feature in Cyclone V devices, connect VCCBAT to a 1.5-V, 2.5-V, or 3.0-V power supply. Cyclone V power-on reset (POR) circuitry monitors VCCBAT. Cyclone V devices do not exit POR if VCCBAT is not powered up.
