Because of the chemicals and metals which are used to make it, a battery can only produce dc (direct current).
For the same reason a battery cannot produce ac (alternating current) on its own, but it can be connected to another device, which is called an invertor, to produce ac for use by devices which require ac instead of dc.
Many of the devices and other pieces of equipment to which a battery can be connected will only work on direct current (such as, for example, car starter motors) but some things (such as light bulbs) can work on either dc or ac.
Some batteries are rechargeable but they cannot be recharged using ac . That is why all battery chargers which are designed to plug into house ac power sockets must convert the ac to dc.

An inverter is the apparatus that changes direct current (DC) to alternating current (AC). It does this by converting the fixed voltage and direction of DC electricity into an oscillating voltage and alternating direction of AC electricity.
No, alternating current (AC) is a type of current in which the flow of electric charge periodically reverses direction. It continuously changes magnitude and direction in a waveform pattern, unlike direct current (DC) which flows consistently in one direction.
Thomas Edison promoted direct current (DC) as the preferred method of electrical distribution. He believed DC was safer, cheaper, and more efficient than alternating current (AC) which was being championed by his rival, Nikola Tesla.
Outside the battery, it is negative to positive and inside the battery it is positive to negative.
The main division is between alternating current (AC) and direct current (DC). AC is universal now for domestic and industrial supply, but DC used to be used in some places in the early part of last century. Automobiles use DC at 12V which is I think universal now. AC in domestic use can be at 50Hz (Europe and many other places) or 60Hz (North America), and can be at either 240V or 120V.
No, that's Alternating Current.
An inverter is the apparatus that changes direct current (DC) to alternating current (AC). It does this by converting the fixed voltage and direction of DC electricity into an oscillating voltage and alternating direction of AC electricity.
Alternating current changes direction on a set frequency such as 50 Hz, 60 Hz or 400 Hz. Direct current always flows in one direction.
Alternating current. Direct current is used in batteries.
Perhaps you are referring to DC and AC? DC is direct current - current flows in a single direction. In AC (alternating current), the current regularly changes its direction.Perhaps you are referring to DC and AC? DC is direct current - current flows in a single direction.

Alternating Current which reverses its direction regularly at certain intervals Direct Current flowing continuously in one direction only
Alternating current is better than direct current for transmission.
Power lines carry electricity as alternating current.
Diode rectifier
DC stands for "direct current", AC for "alternating current". A direct current flows in a single direction; an alternating current changes its direction all the time, typicall 100 or 120 times a second (twice the frequency, which is measured in hertz).
An electric current that periodically changes direction is called an alternating current (AC). In AC circuits, the flow of electric charge reverses direction many times per second, typically at a frequency of either 50 or 60 Hz. This is in contrast to a direct current (DC) in which the flow of electric charge remains constant in one direction.
To convert direct current to alternating current you need either an inverter or a motor-generator set.
