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
Sounds like the battery is dead or you have a loose/dirty battery connection. Have the charging system and battery tested at your local auto parts store.

Buy an inverter from any auto parts store or a large store like Wal-Mart. This converts your 12 volt DC power to 110 volt AC power - but this sort of power usage can drain your battery fast, use with caution so that don't end up unable to start your car again.
I go to my local hardware store to buy things like that. Stores like Best Buy and ACE carry battery jump starters also. Your local auto parts store should have battery jump starters also.
Decrease the brightness of the LCD screen Use "screen blank", "standby" and "hibernation" modes to save power If you will not be using the computer for a long time, remove the laptop battery pack and store it in a cool place. Do not recharge until all battery power is used. Do not use the laptop battery until it is fully charged. And remember the best way to get the most from your laptop battery is to purchase a good quality produced battery like those by mcVolt.
The battery ,which gives power to the truck, looses its power because the lights use power from the battery to work. It's just like a batery for a toy.
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.
If you have no battery then you have no power.
A battery is creates an electricflow and is used to power anything like light bulbs, motors and buzzers.
If you have no power to anything it sounds like a battery problem.
Either the battery has a dead cell and needs replacing or something is on pulling power from the battery.
