Automatic dual battery charger mobile communication apparatus

[0001] There are many battery charging methods used in to-days portable or user carry on electronic communication devices. Such one commonly known system found in mobile phones or note book PC, note pads, tracking apparatuses or other portable electronic devices, wherein the mobile communication device contains an internal battery and when the battery goes low the user plug's the communication device to an A/C outlet or car cigarette lighter plug to charge the battery to operate the device. Unfortunately this method is not practical in use primarily when the mobile communication device battery goes low and the user has no access to an A/C outlet neither to a car cigarette lighter adaptor to charge the battery, in such conditions the mobile communication device becomes useless.

[0002] In event if such mobile communication devices were to use in applications wherein the communication device required to be securely attached to a person such as an offender, in this case when the communication device battery goes low the offender will be stranded at least for 3 hours to an A/C outlet or to a vehicle cigarette lighter adapter to charge the mobile communication device battery, and if happens that the offender is located in an area where there is no A/C outlet or car cigarette lighter adaptor to charge the tracking device battery, the offender's mobile communication device becomes un operative and the offender falsely will be in a violation condition.

[0003] Recently there have been new improved methods used to overcome this problem, such that when a mobile communication device internal battery goes low, the user can plug an external detachable battery to supply power to the mobile communication apparatus electronic circuitry, and charge the mobile communication internal battery, the external battery during charging the internal battery additionally have to provide power to the wireless communication electronic circuitry, thus putting the external battery under hi current discharge condition, by supplying power to charge the internal battery and simultaneously supplying power to the communication device electronic circuitry, the current drain will be hi in particularly when the mobile communication initiates an outgoing call wherein hi current is consumed from the battery, as common knowledge the higher current battery discharge condition will shorten the battery cell live.
