All cells drop in voltage as they lose their charge. Often old cells do not attain full voltage even at their maximum charge. It's just the way the chemistry works. Electronic systems that require constant voltage have regulation circuits that step the voltage up to the necessary level and keep it constant, even though the battery voltage may be dropping.
The number of cells in a battery determine the battery's voltage. Different types of batteries have different cell voltages. The cell voltage is dependant on the reactive metals used. A typical car battery will have six cells. Because a typical cell voltage has a source voltage of approximately 2.0 volts, this makes a car battery produce a voltage of 12 volts.
A solar cell does not store electricity. It charges a battery that stores electricity. The voltage of a battery can be found by connecting a voltmeter to the battery terminals.
2.00V
Voltage would be that of 1 cell.
Lots of things have an electrochemical cell in them. That electrochemical cell is a battery. You cell phone has at least two of them. There is a small one that "keeps alive" memory if you remove the primary battery. A flashlight has a cell or cells in it. We could go on all day. Motor vehicles have a battery, which is a collection of electrochemical cells. Note that a battery could be composed of a single cell, like the "AAA", "AA", "C" and "D" cells. We call them batteries, but they are a single electrochemical cell. A 9-volt battery, on the other hand, has several cells in it stacked in series so their voltages add. That car battery we mentioned is 6 electrochemical cells "long" so that the voltages will sum to the 12 volts (which is actually a bit over 13 volts).
They used to be either Ni-Cd or NiMH, which made the cell voltage 1.2V. These days they can be Li-Po / Li-Io, which have about 3.6V cell voltage.
A nickel-metal hydride cell (NiMH) is a type of secondary electrochemical cell similar to the nickel cadmium cell.
It is NiMH, the only type available.
It depends on the chemistry of the battery. A common alkaline or zinc chloride non-rechargeable battery will be about 1.5v per cell. a NiMh or NiCd rechargeable battery is usually quoted at 1.2v per cell, Lithium Ion cells are generally quoted at 3.7 volts and lead acid at 2v per cell. Divide the pack voltage by the individual voltage of each cell and you will find out how many cells are in the pack.
Depends on the cell/battery chemistry. The most common voltage for a cell is 1.5V, but you can have anything from 1.2(Ni-Cd, NiMH) to 3.7(Li-Po, Li-Io). An automotive battery cell produces 2.2 volts.
The cell voltage.
Battery voltage / number of cells = cell voltage 12/6 = 2 volts cell voltage

There is no standardized voltage for wet cell batteries, but 1.5 V is a common value.
Depends on the number of cells and the chemistry being used. A 3-cell Alkaline battery would be 4.5V while a 3-cell NiMH would be 3.6V
A voltage source is anything that provides a voltage; for example a cell or battery, or an electrical outlet in your home.
