Battery charge time It takes approximately two hours to fully charge a battery. A battery charged in a wireless handheld generally takes longer to charge than a battery charged directly in the battery charger. Simultaneous battery and handheld charging You can charge a battery in the battery charger and charge a battery in a wireless handheld at the same time. If you do this, the battery in the wireless handheld takes priority. Both batteries are charged; however, the battery in the handheld will likely finish charging before the battery in the battery charger. © 2003 Research In Motion Limited. All rights reserved.
