Because batteries have fixed polarity, whereas AC requires that the polarity is switched, normally 50-60 times per second.

How a Seminar on Why can not you store AC power in battery like DC power?
WE can not change the AC power because AC power has two magnitudes one positive and the another one is negative.when we store the AC power in positive half cycle it store the energy and in the negative half cycles it discharge the energy so it is not possible for store the AC power like DC power
Will a compaq nc6000 run on ac power when the battery is dead?
A Compaq nc6000 will run on ac power when the battery is dead. The battery is long lasting but it can be charged by using ac power.
Is a battery consider AC power?
No. A battery is considered to be DC power.
Why can not you store AC power in battery like DC power?
Because ac is of changing polarity. It means the positive terminal becomes negative and vice versa... And this happens 60 times a second! So if we want store this, the terminals of the battery should be changed at the same speed as that of the supply which is not practicable ( and in theory it can be done by a electronic switch which constantly changes its polarity). So its better to convert this ac to dc, store it and then again to ac as in the case of a UPS.
Is recharging while using bad for the laptop battery?
No. When a laptop is plugged in, it immediately switches to AC power and begins charging the battery. The battery cannot become "overcharged" because special circuitry in the battery is designed to prevent this.
What are the two power sources that power a laptop?
* Electric Power * battery
Can a 220 volts ac fan run in a 12 volts battery?
No. You cannot use any battery for it.
Is battery ac powered?
No, batteries provide DC power.
Why dc series motors cannot be used in home?
DC series motors run on DC power. Homes have AC power, not DC power. You could use DC motors in homes if you have a power supply or use a battery, but it is usually more cost effective to use an AC motor.
Can you hook up AC power to a car battery?
Usually a car battery, but it also depends on the size of the battery.
When your computer says its running on AC power what does that mean?
it means it isn't using power from the battery. it is coming strait from the outlet...aka battery is charged and its not using battery power
Is there any problem to laptop bcz i removed the battery and iam wrk on laptop with ac power?
If you are running the laptop off an AC adapter, there is no problem if you keep the battery out - however I keep my battery in, just in case if there is a power failure.
