There is no charging circuitry in the battery pack. The CMD-J5/J16 has complete charger function internally. 
 
The telephone can be charged only with the battery connected the phone. This situation can be sub-divided into 
two situations: the phone is on or off. It can be charged with the AC Adapter, Travel Charger or Cigar Lighter 
Charger. 
 
The battery symbol is used to indicate the charging, and to indicate when the battery is fully charged. This is done 
using the following sequence of icons: 
 
 
 
The uncharged segments of the battery are moving in a right to left manner until the charging stops. The 
sequences for each charging level is repeated until the battery is charged to that level. 

 

When the charging sequence is finished the flashing of the battery level sign stops.  
The phone shows the full-battery icon.

 

 
 
 
 

 
The battery pack contains a single Li-ion cell, a safety circuitry and, in addition, a microprocessor unit which 
manages RTC information by reading out the binary counter value in the microprocessor. The charging circuitry 
and the safety circuitry together guarantee a double fail-safe battery pack. This means that each component can 
be either short or open and still all the safety requirements will not be violated. 
 
The safety concept protects against: 
Over voltage: The charging is stopped when Battery Voltage (Vbat) reaches 4.25V- 4.3V. The charging resumes 
when Vbat falls below (4.025V - 4.125V). 
 
Under voltage: When the cell voltage drops below 2.242V – 2.358V the cell is disconnected for discharging. 
Charging is still possible.  
 
Current fuse: Finally, if all protection functions are out of order due to abnormal condition, the current fuse protects 
the device from explosion and fire with melting. The fuse melts 10A during 1 second.

The phone can be charged even during making phone calls.  
However, the shortest charging time will be reached when the phone is switched off.
