    I have been looking online and I cannot find anything on it really.

    Ive been thinking about what might be healthier for the battery as far as letting it charge up.

    I keep hearing "Charge your iPad 30% faster" or "2 times faster in charging" etc

    But is that really healthier for the battery to pump more juice into it?

    and is it more benifical for the battery to charge slower

    ie
    Charging it 10watts 1amp
    Charging is with 500 miliamps
    and so on.

    You can't charge a Lithium-ion any faster (only slower) than the internal control circuits allow. Go here to learn any and all about battery tech.

    It is "people" who are trying to separate you from your money!:p

    I just put my iPad on charge overnight every few days and not worry about it.

    Easy, follow Apple's guidance. http://www.apple.com/batteries/ipad.html

    Battery technology is constantly changing, best to take guidance straight from the source. Other sources may have very good information, but it can be dated as technology improves.

    iPad will not charge with a mere 500mA.

    There is no such thing as an iPad 10W, 1A charger. It's 10W, 2A. Ohm's Law, W=IR. 10W = 5V * 2A. The iPhone charger is 5W = 5V * 1A, the standard USB spec calls for PC USB ports to provide 2.5W = 5V * 0.5A(500mA).

    And as mentioned, the internal 'smart' control circuits handle battery care. From the consumer standpoint, you don't really need to worry about it.

    Ultra Fast is only for systems that support it. The "wall wart" or USB plug is only 1/2 of the charging system. The "other" 1/2 is built into the iPad. The built in 1/2 is also the "intelligent" part that governs all aspects of charging and discharging.

    Any compony claiming to sell a charger that is "faster" that the iPad "wall wart" is scamming.

    Ultra Fast chargers are used on some systems like electric cars.

    Thanks for all the info. I appreciate it.

    I honestly came across this issue because my dog decided to eat apart my wall mount leaving me with just my pc to charge my iPad which I did last night but when I got home from work it is 100 percent.

    I also go that no "not charging" app on cydia to better monitor the drain of my batter while plugged in.

    I just came across all this battery info that blew my mind.

    Like the Ai charger from Asus, which gives me a BSOD and had to remove.

    Lol my devices have been threw hell in the past day
