Apple says that the iPad 1 has a 10 hour battery life. but this can be shorter, or longer, depending on screen brightness, WiFi and/or 3G usage, loud volume etc.
The Apple iPad 2 is said to have a battery that lasts for 10 hours on a full charge. Unfortunately, the battery life does decrease over time, so to delay this decay, make sure that you are properly charging your iPad 2. After a full charge, use the tablet until its battery indicator shows a red status, indicating that a charge is necessary. By constantly charging the iPad before its battery is this low, you'll be speeding up the aging of its battery.
