4.     Charger Maintenance and Precautions for Using

  • Check the battery technical specification very carefully before charging, to make sure it matches the charger technical data.
  • Make sure charger output connect to the batteries on correct polarity.
  • Input/output connectors must be connected firmly during charging.
  • Reverse connect of short circuit are prohibited during charging.
  • If charger of battery found to be abnormal or damaged during charge, please unplug Input and output wires right away.
  • If use other input wires, make sure the cable can withstand for the maximum input current of the charger and the charger’s input voltage is within its working scope.
  • If you need to extend the output connection cable, please make sure the cable can withstand for the maximum output current of the charger, and the voltage-drop between the charger and connection wire of the battery should be less than 1% of the battery voltage as possible. Otherwise, it may affect the effect of charging process.
  • High voltage and dangerous inside this charger, when there’s a defect, please contact with factory. Users and the maintain person who is not professional staff in our company are forbidden to open or re-develop this product.
  • Never use during a lightning storm.
  • Don’t wet the charger body; never use is in wet or rained place.
  • Never use it near the heat source or where is shined by the straight sunshine.
  • Never use it in or near the place of flammable gas.
  • Use it in the ventilated and dustless place.
  • Don’t place rod of other metal objects at vent or other openings.
  • Never cover the air vent, always leave 10cm space for it at least.
  • Don’t shake, bump or throw it strongly.

5.     Charger Use Method

  • Close the power switch firstly
  • Connect the batteries to the output socket with output wires—positive to positive, negative to negative
  • Plug the input wires correctly and connect to the input power source then
  • Open the power switch, LED flashes blue means battery is being charged
  • LED always green means battery is fully charged, switch off the charge
  • Disconnect the input cable
  • Disconnect the output wires

6.     Charger Features

  • High efficiency, small size, light weight: Charger control circuit adopt advance LLC Half-bridge resonant soft-switching power supply control technology, proper structure as well as nice thermal design make the charger small and light with good portability.
  • Switching power supply type and MCU controlled charging technologies, exclusive precharge mode supplies activate, repair and prolonging life functions for long-term unused or deep sleep batteries.
  • High reliability: The charge is made of high quality military and industrial levels components. Advanced circuit design and strict production process according to ISO9001:2008 quality management system make the charger with low reject rate, high reliability and long service life.
  • The charge is reliable with multiple protections, such as over temperature protection, output short-circuit protection, reverse polarity protection, output over-voltage production, that prevent damage by faulty operations.
  • The charge case is made of aluminum alloy with surface oxidation treatment, high-grade, fashion, good heat dissipation ability, high hardness, antioxidative, non-fading

7.     Charging Mode

  • Precharge stage (TI): When the battery voltage is lower than normal standard, the Charger cannot withstand large current charging. The charger will supply small current for charging, which has the functions of activation, repair and battery life extension. When the output voltage reach normal value or at the T1 of the timing period, the Charger will switch to fast charge stage automatically.
  • Fast charge stage (T2): When battery is on the main period of charging, charger will quickly charge the battery with a constant flow, at the maximum current which can be used by the battery. When the battery voltage raise up to the set value, the charger will switch to float charge stage automatically.
  • Float charge stage (T3): The charger will switch to float charge stage, the charging current will fall off gradually, when the values drops to the set value or at the T3 of the timing period, charger will turns off the output voltage automatically, battery charging is complete.

9.     Charger Protection Features

Over Temperature protection: When the charger internal temperature reaches Protection point, the charger will stop charging automatically and the LED is always red alarm.

  • Output Short-circuit Protection: When the charger appears short-circuit, it will cut off the output current and the LED is always red alarm.
  • Reverse Polarity Protection: When the battery polarities are reversely connected, the Charger will cut off the connection and the LED is always red alarm.
  • Output Over-Voltage protection: When the charger output over-voltage, it will cut off the output current and the LED is always red alarm.

10.      Charger LED Indicator:
