Ni-Cd, Ni-MH and Li-Ion battery blocks, which have different capacities can be charged
while they are attached to the radio or removed from radio. Charger operates according to
the fast-charging technique. After the battery has been charged, it passes to the buffer
charging. While a smart battery is attached to the charger, it gives information about the
situation (charge has began, charging is going on, charging has finished, discharging has
started, discharging is going on, short circuit, maintenance required, error etc.) by the
lighting alerts. Charging or discharging process can be selected. Attached battery block
can be charged after it is fully discharged.
Charging current is limited by electronic circuits for protection.
Desktop Charger Unit LED alerts are given in Table 7-1.
Table 7-1: Desktop Charger LED Warnings
LED COLOR EXPLANATION
Red (Continuously) Battery block is at fast charge *
Red Continuously, sometimes green Charging process is about to finish (>%90)
Green (Continuously) Charging has finished (Ni-Cd , Ni-MH ->Buffer Charge)
(Battery is full>%95)
Orange (Continuously) Battery block and charger connection error **
Red (Blinks)
Battery block temperature is not suitable for fast charging. When the
battery temperature comes to the suitable value range *** device
passes to fast charging automatically.
Red Continuously, sometimes orange
This alert goes on for about 3 minutes. Battery must be discharged
for maintenance (Ni-Cd and Ni-MH batteries only).
Red-Green (in order)
This alert goes on for 2-10 seconds after the battery is being
attached and removed from charger. At this case if battery is
replaced to the charger, discharging has begun (Ni-Cd and Ni-MH
batteries only).****
Green (Blinks)
Discharging (process is being started by the user). Except Li-Ion
batteries.
Orange (Blinks)
Battery is failed. Battery couldn't reach to the required voltage value
or there is short circuit between cells. There may also be a
disconnection at the positive end of the battery.*****
* : Because of block-temperature-control fast charge is applied to Ni-Cd or Ni-MH battery block after 3 minutes the
replacing the battery to the charger is the conditions are appropriate.
** : A permanent failure had been occurred at the battery block circuits, unapproved or unprogrammed battery.
*** : Starting fast charge temperature range can change according to the battery type.
**** : If battery is replaced to charger at first and then removed from charger with in 2-10 seconds to start discharge
process, LED begins to blink red-green. To start discharging battery is replaced to the charger again.
***** : This situation occurs at the battery which hadn't been used for long time and thus couldn't reach to the normal
voltage level or at the short circuit occurred battery blocks after 20 minutes. It also occurs at the battery whose positive
end connection has broken, as soon as the battery is placed to the charger.
