This charger is a charger for 5pcs. 34 series Stinger THT Ni-MH batteries. The charger will able to charge 5 batteries independence of each other. When each batteries are fully charged, Charger utilizes a method called -dV detection for charge termination. This method is based on the fact that the voltage drops over the Ni-MH cells when the batteries are fully charged. This voltage drop is detected when the voltage has dropped a certain percentage from the highest value. If this drop does not occur, the charger has a safety timer which will terminate charging after a given time period to avoid overcharging the batteries.
A few cels may have a voltage drop in the first part of the charge cycle. This is especially true for battery cells which have been idle for a longer period of time. Because of this, a timer is built into the charger which prevents -dV detection the first minutes of the charge cycle.
LED Displays
Red: In Charging Mode
Green: Fully Charged/No Load
Red LED Blinking: in Short Circuit or polarity reverse
Green LED Blinking: repair the charging with smal current
• Ni-MH chargers are designed for charging Ni-MH batteries only.
• Make sure you have the correct battery charger for the battery you wish to charge. The number of cells must correspond to the ouput indicated on the charger. Never charge more battery cells than the charger is made for.
• When charging seperate battery cells, avoid charging cells with different rest capacities at the same time.
• Do not attempt to charge batteries that are not rechargeable.
• Please check that the specification for your battery allows for the maximum charge current indicated on the charger. If in doubt, contact the battery manufacturer for details.
• Please check that the specification for your battery allows for the enviromental conditions present during charging. Do not charge batteries at too high or too low temperatures.
• Please ensure correct polarity when connecting to the battery terminals. Reverse polarity connection may, in some chargers(see the charger specification), result in a fuse rupturing, leaving the charger useless.
• The charge cycle starts when the charger is connected to mains and “turned on” by turning ON/OFF button to the “ON” position.
• If the charger is disconnected from the mains voltage during a charge cycle the charger will start a new charge cycle when it is reconnected to the mains.
• When charging is complete, disconnect the charger from the mains or switch the ON/OFF button on the product to OFF before disconnecting the battery connections.
• The -dV level will adapt to the number of cells and will be approximately equally sensitive for all number of cells.
• The safety timer will protect the batteries if a -dV signal fails to appear during charging. It is normal to have a safety timer that is longer than the max. charge time.
• Top-off charge following –dV detection ensures that all cells in a battery pack reaches full capacity (are balanced) prior to trickle charge.
• The charger is designed for the lowest possible leakage current from the battery when mains is disconnected (<1mA). Even so, it is recommended that the batteries are disconnected from the charger when mains is not connected.
• On request the charger may be supplied with battery temperature monitoring. A built-in temperature change control (+dT/dt) secures optimal charge with a built-in NTC resistor in the battery pack.
When the enviromental conditions specified in the product instructions are met, the product box is opened.
After opening the product box, the AC power cable inside the product is connected to the “INPUT UNIT” which is labelled near of the power plug, and the product is connected to the mains.
After the AC power connection is made, the product is switched on by switching the “POWER ON/OFF” which is labelled near of the red button, switch to ON position. After switching the power switch to ON position, the LED of the red switch will light up.
Battery LEDs in the “LED Display” area are positioned separately for each battery.
These LEDs specifies that,
RED : Battery Charging Mode,
Green: Fully charged/no load,
Flashing Red: Short Circuit or Polarity reversed,
Green LED Blinking: repair charge with small current.
For each battery LED in the system,
When the mains is connected the LEDs will be orange for the first seconds and then turn to green when the initialisation and analysis starts.
The LED will be green when the battery is not connected or when the battery is fully charged. When a battery is connected that is not fully charged and not at a low voltage level, LED will be red which specifies battery charge state. The LED indicator will be red during the battery charging mode, the LED will be green when the battery is fully charged.
The charger applies a low-current soft start on deeply discharged batteries. Until the voltage reaches normal level within a certain time, the charger enters trickle charge mode and the green LED will flash.
The product will enter short circuit protection or reverse polarity protection in case of short circuit condition of battery contacts or battery in battery areas. In case of short circuit or reverse polarity protection, the LEDs will be flashing red.
After the batteries are fully charged and if the product will not be used for new charge cycles, the “POWER BUTTON” is switched to OFF. The batteries can then be removed from the area. The connection between the mains and the product can be unplugged.
You may manually start a new battery charge cycle by disconnecting charged battery from area and connecting new one again.
