Typical Discharge Times
This depends on condition and frequency of the battery usage. The following are
approximate figures (From Full charge)
NP-23/NP-23dx/NP-1dx ------------- 75 minutes
NP-H50/NP-H50dx ------------------- 120 minutes
BP-95S/BP-95dx ---------------------- 160 minutes
SPECIAL FEATURES
• Independent Charge/Discharge. Although the i400 is a sequential charger/discharger, it is
designed to fast charge one channel while independently discharging another. This saves the
operator valuable time when conditioning batteries.
• Low Voltage Batteries. Batteries with low voltage will not be recognized as chargeable until the
unit’s initial conditioning sequence has brought them up to a valid voltage level for fast charging.
• Two Battery Types. The unit will charge either BP or NP type batteries, however it always gives
priority to BP batteries. Inserting a BP battery in the same channel as an NP will disable charging
of the NP.
• Safety. The unit will automatically detect abnormally high or low voltage batteries or defective
batteries and will not permit charging. The channel in question will be skipped and the LED will
not come on.
• Uninterrupted Operation. If a battery is removed during or prior to or during charging, the unit
will automatically sequence on to the next available battery channel.
• Digital Negative Delta V charging. Using fully digital microprocessor controlled negative delta
V charging method; the unit will handle most manufacturers’ NP-1 or BP-90/95 style batteries.
From 12V~13.2V and 1Ah~7Ah.
Battery Protection Features
Following are a list of basic charger protection features for User recognition
* Low voltage battery
a. If the battery voltage is below or equal 5.0V
The battery will not be charged, (no charger LED)
b. If the battery voltage is 5.0~10.5V,
The unit starts conditioning charging (red LED lights) and automatically starts quick
charging when the battery voltage recovers to reach 10.5v. If the battery voltage does not
10.5V after 30 minutes of conditioning, charging will be stopped (orange LED blinks).
*Over charge protection
If charging does stop due to faulty battery or some other reason, a circuit protection timer is
automatically activated and stops charging.
If the battery is not charged after 260minutes (4 1/2Hrs) of charging, the unit stops charging.
If battery voltage is 13.0V, Green LED lights indicating usable battery. If the battery voltage
does not reach 13.0V, orange LED lights indicating fault.
*Over voltage protection
Over voltage protection circuit stops charging if the battery voltage does not reach specific
figure within specific time.
If the battery voltage reaches or exceeds 21.5V during quick charge is in progress, charging
will be stopped. Orange LED blinks)
D COLOR STATUS LIST
Full Red…….….………fast charge in progress
No LED………….……. charge waiting (when battery inserted)
Full Green………..……charge complete, trickle charge in progress
Blinking Green………..discharge in progress
Full Amber……….……discharge waiting
Blinking Amber………..defective battery (check battery specifications)
Blinking Red……….…..defective charger (return for service)
