It's definitely normal... a significant amount of amp draw on a battery will
drop the measured voltage... the led lights measure voltage. On a fully
charged battery when you turn on the fridge (engine not running) the led
lights will switch from green to yellow in a short time.... if you then turn
off the fridge, right after it switching to yellow, you will notice the led
switch back to green as the voltage pops back up after removing the amp draw
of the fridge.
