it is 12v
That depends on the battery. A car battery makes 12 volts. An AA cell battery makes 1.5 volts.
Depends on size.
Alternator is sending to much volts to battery. Suppose to turn itself off when battery gets to around 13 volts. May need new alternator.
1.5 volts
If the battery is fully charged it will give you roughly 24 hours music playback or 5 hours video playback Hope this helps :)
Automobile battery is 12 volts. If it is fully charged you should actually read 12.6 volts.
1.2 volts
No, a 220 volts AC fan cannot run directly from a 12 volts battery. The fan requires a much higher voltage to operate efficiently. You would need a power inverter to convert the 12 volts from the battery to 220 volts AC to power the fan.
Actually doing ANYTHING on your ipod touch whether it be listening to music, or pressing some buttons will drain the ipod battery. some things drain less battery then other things, but they all drain battery. (for example, listening to music does not drain as much battery as watching a video.) I do not know any buttons on the ipod touch called the hold button, but if you are talking about the button in the front with a square on it, that does not drain battery. if you keep holding it, a whole lot of options might open, but it does not drain battery. If it DOES drain battery, its so small of a drain that you won't notice it and it won't impact your ipod's performance
8 hours of video
The iPod Video does not exist, but look on the bright side. The iPod Touch now has two cameras! A front and rear, much like the iPhone 4.
you cant just buy a battery you gotta buy a new ipod
