N SERIES

Thank you for purchasing the ISDT N8/N16/N24 Smart Charger.
The Series N is an intelligent battery charger that is compatible with multiple types of AA/AAA size
cylindrical batteries. Each channel works independently of each other which means that dierent types
and dierent sizes of batteries can be charged at the same time.
For safety and for a better user experience, please read this user manual in detail and follow the
instructions carefully before using your new charger.
1) Never attempt to charge a damaged battery or a non-rechargeable battery.
2) Keep the charger away from humidity and high temperature while it’s working and ensure that the
charger is not covered in any way which may prevent ventilation required for cooling.
3) Do not let young children operate the charger.
4) Make sure that the charging and discharging parameter settings are suitable for the batteries being
charged as incorrect setting could lead to damage to the batteries and the charger or even re .

How To Determine The Battery Type
Usually, the battery chemistry type and the rated voltage are stated on the sleeve of the battery. The
charger will attempt to automatically identify the battery type based on the built-in detection
algorithm but please select the battery types manually if the charger chooses the wrong one.
* NiZn and LiHv batteries need to be selected manually.

Operation Instructions
With the N Series of battery charger, 8 / 16 / 24 cells of AAA or AA batteries of the same chemistry can
be charged, discharged, analyzed and activated increased in a variety of combinations. When charging
with the battery type selected to be 'Auto', NiMH and Lithium batteries can be charged simultaneously.
1) If you are using the N8, the charger is powered via the USB socket. Connect the auxiliary USB cable
with any USB power adapter and the N8 is turned on and ready for use. The N8 can be powered from a
wide range of USB power adapters and it can automatically identify and adapt to the optimal charging
power.
When the charger is N16 / N24, connect the power adapter supplied with the charger, the N16 / N24 is
turned on and ready for use.
2) Before the battery is inserted, please long press the ○touch key to enter the system setting interface
to preset the task and parameters in the charger.

Standby Mode
No batteries are inserted or when the batteries are fully charged, if the charger is not operated within
ve minutes, it will automatically set the display backlight to the minimum brightness level and the
charger will enter standby mode to reduce power consumption. In standby mode, inserting or
removing a battery or pressing any button will activate the charger automatically.
Capacity Plus Charge
When the user selects the battery type as NiMH/NiCd/Eneloop and the task as Charge, an additional
charging option of the task setting interface can be set. If this mode is selected, the charger will
automatically discharge the battery rst and then automatically recharge to full capacity so as to
eliminate the memory eect of the battery, and where possible, increase the capacity of the battery.
3) After correctly setting the parameters and inserting a battery, the charger will beep and sound a
prompt tone. Charge or discharge will start based on the setup parameters selected and the working
status will be displayed on the screen as shown below:
*The taskbar shows the status of each task visually.
