Can a 9v battery be used at a depressed voltage?

Also the actual durations over which each voltage can be exceeded with a few current levels that would be typical for applications that specify 9v batteries.R It's a valid criticism that nobody uses a battery at such depressed voltage levels.

Can a 9v battery output 0.6V?

After all, it is a 9v battery and output at 0.6v is likely to be irrelevant for any application that specifies a 9v battery. Also the actual durations over which each voltage can be exceeded with a few current levels that would be typical for applications that specify 9v batteries.R

How many a current does a 9v battery maintain?

5. A 9V battery maintains a current of 3 A through a portable radio. What is the resistance of the conductor? 6. What is the resistance of a 1100 W hair dryer plugged into a 110 V outlet with a 10 A current flowing through it?

Should I use a 9V or 6V battery?

Something like 1V max drop over the full discharge curve is about the worst case you should be considering with a 9V battery - after all you wanted 9V, not 6V, or you'd use a 6V battery? resistance) depends strongly on temperature.

Can I use 9V batteries for Arduino?

I routinely advise people NOT to use those small 9v batteries for Arduino projects. A pack of 6 x AA cells would make a lot more sense. You can also run an Uno or Mega from 3 x AA cells (4.5v) connected to the 5v pin - which avoids the energy waste in the voltage regulator.

Which battery performs better – Energizer Max or duracel?

It follows that for any load from infinity down to the internal resistance of the battery, the winner (at short-circuit condition) will perform better than the competition. As an example, the Duracel and Energizer Max had equal inrush and steady state currents. However the short-circuit voltage of the Energizer was slightly higher.
