Disclaimer and warning
Thank you for purchasing the ISDT C4 smart charger.
C4 is one of the smart chargers which has excellent
performance and supports almost all types of batteries,such
as Li-lon,Lihv,IM-R,IN-R,Ni-MH,Ni-cd,Lifepo4,eneloop.It has
high angle visible IPS display,detailedparameterandtask
progress.Dierent types batteries can be put into dierent
slots and operate independently.The charger will identify
battery type and choose the matched charging way.
Read this user manual and follow the instructions carefully
before using your new charger.
1,Never charger an non-rechargeablebattery;
2,Keep the charger away from humidity and high tempera-
ture while
charging,and ensure the cooling fan heats sinking smoothly;
3,Do not let the children close to the charger.And do not
leave the charger unattended.
4,Make sure the charging and discharging parameters is
correct.Incorrect setting of parameters will result in disastrous
consequences.
5,When the charging or discharging is completed,please cut
o the power and remove the battery as soon as possible.
Multiplecombinationmanner could be used to charge,-
discharge,storage or circulate batteries,like 4s AA /2s
AAA/2s 18650/1s 26650.
Put the battery into matched slot,and then the charger
will start charge task automatic after buzzer 3
times.Meanwhile,users could touch the touch key to stay
in the task page and change each parameter manual-
ly.The items are as follows:
Usually,there are battery type or rated voltage on the
battery surface.Users could compare the below list to
conrm it.The charger will identify battery type automat-
ically based ontestingthevoltageofbatteries.And
please select the battery types manually if the charger
choose the wrong one.
* NiZn,LiHv batteries needto selected manually.
1)Connect the charger to a AC outlet(100-240V)or
vehicleadapter.
2)Put the battery into C4 according tothe positiveand
negative pole,then the boot screen comes up and will
shows charging state(as below pic)after buzzer 3 times.
Thetaskbar shows each task statusin one visual way,
means charging, means discharge, activate,
means circulate,analyze.After any task is complet-
ed,the will displayed on the screen instead of battery
percentage .Each detailed task page would be cycle
through thewindows. Use button tocycle
between modes.
