hi if ur gage keeps dropping and u run out of juice in ur battery it could be one of two things 1) bad battery or 2) bad alternater
Weak battery, or weak alternator.
Sounds like the alternator is going bad, Need to check charging system with a volt meter.
A battery gauge "moves up and down" while running because of fluctuations in the voltage output of the circuit which it is connected to. This may be because of equipment on the circuit.
More information is needed before this question can be answered. Is that "temperature"? Are you talking about the temperature gauge? And what is it on? A car? A refrigerator or freezer? The thermostat? The world outside?

Are you SURE your car is 16 volt?? I've seen 6 volt systems and 99.9% of the cars are 12 volt. So double check you numbers. I have NEVER seen a 16V battery in a car.
Can be loose connections or the alternator is failing.
The fuel cutout light has nothing to do with your battery level....if the level keeps flucuating (gauge needle going up and down) more than likely the alternator has a problem or you could have an electrical or grounding problem somewhere. I have all of the above at the moment. My gauges kept dancing up and down and then the alternator went. (Oh, the voltage regulator is built into the alternator, so you'll be replacing both at the same time if that's the problem.)

The amperage gauge will go down when you turn on your lights, because there is a sudden draw of electric power from the battery. The alternator should equal out the power surge.
