If the device is running off battery, the output voltage of the battery will be increased by circuitry to run the device at the required level, however the voltage of the batteries themselves decreases as they loose power (and this is how the amount of charge left is calculated) When you have a power supply, it needs to provide the correct voltage.
So never ever try to connect a battery to the AC supply at home, lab or elsewhere. Now lets see what happens if you connect a 12VDC battery to the 110/230V and 12V AC? If we connect a battery with an AC source (say 120V or 230V AC from a wall plug), It may heat up and explode with a boom having risk of serious injuries and hazardous fire.
When you remove the load, the voltage recovers quickly. But with lead acid or alkaline batteries, it may take a lot longer to recover to the final open-circuit voltage after removing the load. In other words, it is more complicated than a voltage source in series with a resistor.
If the system reaches the equilibrium situation now, the amount of separated charges and voltage will be less (because more charges have to be created). A new battery will have much less loaded voltage drop than you have. An old, worn out, or damaged Lithium battery has a much higher internal resistance than a new battery.
The only time you're exclusively on battery power is when the engine is off (or, of course, if the alternator has failed). With the engine running the alternator supplies current that both recharges the battery- or, once it's recharged, maintains the charge - and runs the rest of the stuff on the car.
For this reason, a DC equipment should not be connected to the AC supply and vice versa. In simple words, A battery is DC operated device and should not be connected with AC source of supply. Good to know: The battery electrodes are known as Anode and Cathode.

Are Batteries AC or DC? The Ultimate Explanation
Batteries produce DC through chemical reactions that occur within their cells. For instance, in a lead-acid battery, a reaction between lead dioxide and sponge lead in an electrolyte solution generates electrons. These electrons then flow out of the battery to power connected devices.

What happens if an AC voltage is applied to a battery?
It''s fairly common to see a lead-acid battery charged using rectified AC. As long as the charging current isn''t beyond the capability of the battery, it will ''work''. If there isn''t a series resistor somewhere, or some primary-side limiter, the winding resistance of the transformer could be what''s limiting the charging current.
