The voltage between the two electrodes of the battery depends on the redox reactions going on at the electrodes. The overall reactions stay the same, so the electromotive force stays about the same too. The electromotive force is however dependent on the concentration of the reactants the electrolyte, and the voltage at the outside of the battery depends on the internal resistance of the battery as well, which can be much higher when the battery is used.
A battery is energy stored in a chemical way. When "converted" into electricity, the chemical looses power, either going from a base of very low PH to neutral or from a base of very high PH to neutral.
A fresh battery gives out a "high" voltage and slowly as it is discharges, the electrolyte inside will reach a PH of 7 (neutral) and voltage drops accordingly.
The voltage can not drop below zero, as the electrolyte has lost all its power when it reaches a PH of 7.
Chemical reactions work only one way, reaching PH Neutral as its ultimate goal, where as in AC one have mechanical movement of wire in a magnetic field.
No movement, no electricity. When the wire moves in a magnetic field it produces electricity, but only as long as the magnetic field constantly changes from North to South and back to North again. It is this that creates AC or alternating current, hence the Alternating magnetic poles.

What is the Working of online ups?
Online UPS on the other hand uses an Inverter which always on to give sine wave AC in the output socket. The incoming AC is first converted into DC by a transformer to charge the battery as well as to give power to the inverter transformer. The inverter transformer converts the DC to AC continuously to power the load. If power fails, the battery backup circuit switches on and takes the load. Online UPS is more efficient than the Offline UPS and uses a "Constant duty Inverter". It also has a "Static bypass" system that transfers the load to the AC power if the inverter system fails. The advantage of the Online UPS is that, it clean up the AC waveform by converting it into DC then reconverting this DC to fresh AC.
What is the output voltage of megger is it ac or DC?
megger are available in ac &dc
What is the difference while applying kcl to dc and ac circuits?
KCL is Common to both AC and DC. Only the waveform or AC and DC will differ
What is an ac voltmeter?
A: It is a regular DC voltmeter but the AC is rectified and the DC component is measured and displayed as AC VOLTS.
How can I convert a DC adapter operated device into one that uses a battery?
A: A DC adapter is basically like a battery except it is conditioned from an AC source. To change over measure the voltage when fully operational then switch to battery that have the same voltage as the adapter. the only concern should be the power required
Is Battery is DC or AC?
An alkaline battery's output is DC as is any battery.
Is battery ac or DC?
Batteries are DC
Battery ac or DC?
A battery supplies DC.
Why DC is used in battery's?
dc in battery stands for direct current .ac is alternating current.
When measuring electrical components how can you tell if it will be AC or DC?
Typically DC is what you get in a battery and AC is what powers your house.
Is a battery consider AC power?
No. A battery is considered to be DC power.
Are TV's in buses AC or DC input?
Televisions in buses can be either AC or DC current. It depends on whether the bus is using a DC to AC power convertor or an AC generator or DC power from the battery.
How can a 110 amp battery and 24v alternator give power to a home?
It can't. You home runs on 120 volts AC not DC power from a battery.
Will a 120 volt AC to 12 volt AC adapter charge a 12 volt car battery?
No, the battery is DC not AC.
Do laptop work on ac or DC and how?
A laptop runs on DC. Either from the battery, or the external power supply, which converts AC power to DC.
Is a 9 volt battery ac or DC?
All Batteries are DC or Direct Current.
What does AC-DC conversion and battery charging mean?
The voltage in your house is AC. It is in the form of a sine wave that goes positive and negative 60 times a second. To charge a battery you need DC so you do an AC to DC conversion and then apply the DC to the battery charging circuit that applies the correct charging current to the battery and checks on the state of the charge.
