7.5 Volts
1.5v+1.5v+`n batteries. You didn't say how many cells, but if they're wired in series, the voltage is additive. 7.5 volts
1.5 x the number of cells eg. 1.5 x 6 = 9v
the age of the battery
The voltage depends on how the two batteries are connected to one another. If they are connected in a series circuit (positive end to negative end) the voltage will double. If they are wired in a parallel circuit, (It
Approximately 7.5 volts, under no-load conditions, assuming that each cell is exactly at 1.5 volts each (which I assure you, it doesn't really happen that way in the real world, but it's close enough).When cells are connected in series, the voltage is the sum of all individual voltages. In this case, with 5 cells in series (each at 1.5V), the total voltage would be 1.5V*5 = 7.5V
Voltage sources connected in parallel should have equal voltage. Otherwise the stronger battery would attempt to charge the weaker creating a lot of heat and depending on the type of battery there is the chance of explosion.
Battery voltage / number of cells = cell voltage 12/6 = 2 volts cell voltage
Voltage would be that of 1 cell.
When batteries are connected in parallel, the voltage remains the same as the voltage of a single battery. This is because the positive terminals are connected together and the negative terminals are connected together, so the voltage across each battery remains constant.
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.
If the 2nd battery is connected "in series" with the 1st battery, the voltage will increase & the motor will run faster. If the 2nd battery is connected "in parallel" with the 1st battery, the voltage will not change, but the total battery capacity will be greater & therefore battery life will be longer than when using just 1 battery.
