No, Terminal voltage of a battery can't be zero. For example, if my mobile's battery is at low charge. It is showing only one point of charge on screen, but there will be no fluctuation on its screen, all the other features like audio, video, display will remain same unless it will become fully out of charge. Charge could be zero but the voltage can't be zero.
Well, actually the terminal voltage of a battery can be zero, but only when the battery is totally dead and unable to take a charge (if it was a rechargeable type battery). At this point it must be disposed of.
One exception is wet cell batteries (like lead acid), if the liquid electrolyte is removed the terminal voltage goes to zero but the battery is still good and can be restored to normal operation by refilling it with electrolyte. In fact wet cell batteries are often sold fully charged but with no electrolyte and their terminal voltage is thus zero on the store shelf until the salesman fills them with electrolyte.

Why negative voltage is used in BTS in GSM system?
Because 2 terminal comes out from the battery and through red wire we ground the +ive terminal so that possibility of noise interference will get zero....noise occur only in the +ive terminal.....thats why we use -ive voltage.
What is the difference between the terminal voltage and the source voltage?
the source voltage is the voltage that measured exactly after the voltage source , but the terminal voltage is the voltage that measured in the load terminals , which equal to the source voltage minus the drop voltage on the transmission line .
If a 12v car battery has 0.04ohm internal resistance what is the battery terminal voltage when the battery delivers 40A?
011.1
What is the purpose of the zero ohms adjust?
To adjust for the changing (dropping) voltage of the internal battery, so you can still get accurate readings. When you can no longer adjust to zero, replace the battery(s).
If the excitation of generator changes what happens to the terminal voltage?
By Decreasing the excitation voltage the terminal voltage will decrease and similarly by increasing the excitation voltages the terminal voltage will also increases.
What is the voltage in a circuit?
zero That's not always true. If you have a 12 volt battery not connected to anything and you measure the terminal voltage, it will be 12 volts.

What is open circuit characteristic?
The terminal voltage is equal to the supply voltage and there is zero current.
How many volts does a LR41 battery have?
This is an alkaline battery and will have a typical terminal voltage of 1.5v.
Can the terminal voltage of a battery be larger than its emf?
the voltage of a battery could be larger than the emf if you are to charge the battery, in that case V=E+Ir .
What is the difference between the terminal voltage and the source voltage?
the source voltage is the voltage that measured exactly after the voltage source , but the terminal voltage is the voltage that measured in the load terminals , which equal to the source voltage minus the drop voltage on the transmission line .
Why some time the terminal voltage of a battery increases more than its rating?
When the alternator starts charging the battery voltage will increase about two volts to charge the battery.
If a 12v car battery has 0.04ohm internal resistance what is the battery terminal voltage when the battery delivers 40A?
011.1
Under what circumstances can the terminal potential difference of a battery exceed its emf?
"The potential difference between the terminals of a battery will equal the emf of the battery when there is no current in the battery. At this time, the current though, and hence the potential drop across the internal resistance is zero. This only happens when there is no load placed on the battery-that includes measuring the potential difference with a voltmeter! The terminal voltage will exceed the emf of the battery when current is driven backward through the battery, in at its positive terminal and out at its negative terminal."

Why do you not get battery symbol on your laptop sometimes after you on power supply in your laptop made by Toshiba model no A200?
Note: When interconnecting A200 batteries (cells), they must be identical in voltage and amp rating! Batteries may be connected in series. The positive terminal of the first battery is connected to the negative terminal of the second battery; the positive terminal of the second is connected to the negative of the third, and so on. The voltage of the assembled battery is the sum of the individual batteries. The batteries are connected: + to - to + to - to + to -, etc. The capacity of the battery is unchanged. Batteries may also be connected in parallel. The positive terminal of the first battery is connected to the positive terminal of the second battery, the positive terminal of the second is connected to the positive of the third; the negative terminal of the first battery is connected to the negative terminal of the second battery, the negative terminal of the second is connected to the negative of the third and so on. The batteries are connected: + to + to + and - to - to -. In this configuration, the capacity is the sum of the individual batteries and voltage is unchanged.
Why does a multimeter display a reading of zero when both of its probes are touched to the same end of a battery?
A multimeter? Zero because there is no voltage difference, zero because there's no current flow (amperage) and zero ohms of resistance because they are both touching the same metal terminal. Or, perhaps it reads zero because you have it turned off.
What is terminal PD?
A terminal potential difference is the potential difference appearing across the terminals of a voltage source, such as a battery or a generator, which varies according to the load supplied.When the battery or generator is off load (i.e. no load is connected to it), the terminal potential difference is equal to the electromotive force of that battery or generator.The terminal potential difference tends to decrease as the load current increases, due to a corresponding increase in the internal voltage drop of the battery or generator.
