We generally recommend an overnight charge (approximately twelve hours). Refer to the user's manual for charging instructions.

(Note: it is normal that battery becomes warm during charging and discharging).
New Dell hf674 Battery is hard for the device to charge; they have never been fully charged and are therefore "unformed". Sometimes the device's charger will stop charging a new battery before it is fully charged. If this happens, remove the battery from the device and then reinsert it. The charge cycle should begin again. This may happen several times during the first battery charge. Don't worry; it's perfectly normal.
