Because a battery works by the chemical action of the electrolyte on the plates. The process works slowly, and it works with a constant potential, which is inherently DC.

What are the roles of a diode and a capacitor in an AC-DC converter?
An AC-DC converter you can operate a device on AC instead of batteries. ~bobbyjack~ : D
What does an ac adapter do for a Nintendo DS?
It allows you to use mains power instead of batteries
Is batteries alternative current or directly current?
Batteries store DC, or Direct Current. The correct term for AC is Alternating Current.
Batteries are car batteries ac or DC?
dc
Why cannot store the ac power in battery?
Because batteries have fixed polarity, whereas AC requires that the polarity is switched, normally 50-60 times per second.
Why don't we get most of our electricity from batteries?
Batteries can only store electricity, not create it. Batteries can only store and release direct current (DC), while power plants produce alternating current (AC). Since it takes up a lot of space and it costs a lot to use batteries, the batteries might not be able to store all the electricity that is produced. This is why an electrical generating station does not use batteries to generate electricity.
Why can not store ac in battery?
Batteries are storing charge or free electrons. The state is by nature a fixed voltage rather than a varying voltage. You can convert the battery charge to AC by using what is called an inverter.
How do you identify dc source is connected instead of battery?
"dc" is direct current which is what batteries use, whereas "ac" is alternating current, which is what your household receptacle uses.
Is battery ac or DC?
Batteries are DC
Can AA batteries be replaced with ac power adapters?
No. AA batteries are DC to begin with. The equipment in question may have an AC power jack, though.
Are 6 Volt Car batteries AC or DC current?
DC definitely, all car batteries - all batteries.
Why cant you generate DC directlyinstead of generating AC and converting it to DC?
Yes, by using a dynamo (which produces d.c.) instead of an alternator.
