Quasar Battery. 

 

Trickle Charge 

4 green bars (charger inserted, 
battery fully charged) 

 

When the charger is first inserted, the Quasar will enter a fast-charge mode. In 
this mode, a fully discharged battery can be charged within approximately 5 to 6 
hours. When in use, fast-charge is indicated with moving green bars on the 
Battery Status indicator in the StarLab application software, see Table C-2. 

When the Quasar detects that the battery is fully charged, it reverts to a "trickle-
charge" state, which keeps the battery charged even when the Quasar is in use. 
The "trickle-charge" is small enough not to damage the battery even when the 
charger is inserted for long periods. Trickle-charge is indicated with 4 fixed 
green bars in StarLab. 

If the charger is re-inserted when the battery is already fully-charged, the Quasar 
will initially begin fast-charging, and after a few minutes will revert to trickle- 
charge. 

Fast-charge and trickle-charge function in the same way when the Quasar is in 
use and switched on, or when the Quasar is not in use and switched off. The 
charger can be left plugged into the Quasar indefinitely without damaging the 
battery.
