Trouble-shooting
Description Solution
1 blink every 5 seconds. There is no battery pack plugged on the
connector.
The battery pack is not plugged in cor-
rectly.
Plug a battery pack.
Remove the battery pack and plug it
again.
Description Solution
Yellow - 1 blink Temperature is below operating range
for charging.
Operate within the operating tempera-
ture of charge for the charger and the
battery pack.
Yellow - 2 blinks Temperature is above operating range
for charging.
Let the battery pack cool down to bring
it back to operating temperature and the
error will stop.
Red - 1 blink Battery pack is overcharged, voltage is
higher than accepted range for charging.
Charging will not start.
Leave the battery pack to rest for a cer-
tain period of time (around 5 days).
Try again with another charger.
If the error still occurs, the battery pack
must be disposed of.
Red - 2 blinks Charger cannot retrieve information
from battery pack temperature.
Charging will not start.
Try again with another charger.
If the error still occurs, the battery pack
must be disposed of.
Red - 3 blinks Over-current detected.
Charging will not start.
Disconnect the battery pack from the
charger and reconnect after 5 minutes.
If the same error occurs, try the battery
pack with another charger. A charger
that has this error with different battery
packs must be disposed of for safety
reasons.
Red - 4 blinks Time for pre-charge is too long.
Charging is stopped.
Battery pack may have been deeply dis-
charged. Try to charge the battery pack
one more time to resume normal charge.
If the error still occurs it means that the
battery pack chemistry is not working
properly anymore and so it should be
disposed of for safety reasons.
Red - 5 blinks Time to charge is too long,
Charging is stopped.
Check plugging of the battery pack on
the charger. Poor connection between
charger and battery pack terminals may
slow down the charge.
Red - 7 blinks Cells imbalance is out of range. Charg-
ing will not start.
It is generally due to natural cells aging
or is the consequence of repetitive
strong discharge.
Try again with another charger.
If the error still occurs, the battery pack
must be disposed of.
Red - 8 blinks Charger cannot communicate with bat-
tery pack or the battery pack is not rec-
ognized as compatible.
Check the compatibility of the battery
pack with charger and try again with an-
other charger.
If compatible then it means that the
electronic has been damaged and then
for safety reasons the battery pack must
be disposed of.

EN Trouble-shooting
06/2020 11 / 12
Description Solution
Red - 6 blinks
1 blink every 5 seconds.
Battery pack is strongly discharged and
cannot be charged anymore for safety
reasons.
For charger rev1, it can also be a
communication issue or compatibil-
ity issue (red 8 blinks)
Try again with another charger.
If the error still occurs, the battery pack
must be disposed of.
