    • A battery charger charges a battery in a portable chargeable electronic device, such as a cellular phone, with a long-term-constant current, even while the device is used. The charging current is controlled by circuitry in the portable device, avoiding the need for control circuitry in the battery charger or battery. A battery-charger connector that corresponds to the type of battery in the portable device is keyed to fit only a charger that matches the type of battery, thus assuring proper charging of the battery. Alternatively, a simple contact connects the battery charger to the battery. A belt clip covers the battery-charger connector when the battery charger is disconnected to prevent short-circuiting the battery.
    • 即使在使用该装置的情况下,电池充电器也可以在诸如蜂窝电话的便携式可充电电子设备中以长期恒定的电流对电池充电。 充电电流由便携式设备中的电路控制,避免了对电池充电器或电池中的控制电路的需要。 与便携式设备中的电池类型相对应的电池充电器连接器被键入以仅适合与电池类型匹配的充电器,从而确保电池的适当充电。 或者,简单的接触将电池充电器连接到电池。 当电池充电器断开时,皮带夹会覆盖电池充电器连接器,以防止电池短路。
