NWB-15(GWB-15) li-ion battery mining lamp Portable Charger

NWB-15(GWB-15) portable charger NEW (2008-6)
The NWB-15 (GWB-15) Portable Charger is a desk top charger specifically suited for the KLM5 LED Li-ion Cap Lamp. The charger provides the user with the ability to charge the cap lamp from a standard power outlet. It is small in size, light in weight, and convenient to carry. The newly designed NWB-15 (GWB-15) Portable Charger is more reliable than previous models and has a simple, sleek finish. The circuit board design has been optimized and improved to increase safety and reliability. The chargers shell is made from high quality aluminum alloy. The NWB-15 (GWB-15) is CE Certified for European Union standards.
Usage Guide:
1. The charger is compatible with most standard power outlets; the charger is supplied with an input voltage of 85- 265V and a frequency range of 50-60Hz.
2. Outlet plugs can be supplied for US, EU, UK and AU standards.
3. Connect the outlet plug to the power outlet; the charger indicator light will turn green to indicate the presence of power.
4. Place the cap lamp head into the plug of the charger; turn 180 degrees clockwise until the anode contacts with the chargers cathode; the charger indicator light will turn red to indicate it is charging.
5. Once charging is completed the charger indicator light will turn green. The charging time is approximately 6-8 hours.
Maintenance:
The NWB-15 (GWB-15) Portable Charger requires no maintenance if used correctly under standard operating conditions.
Charging Theory:
The Lithium-ion battery makes use of both constant current and constant voltage charging methods. The charging current is 1500mA 150mA; voltage is 4.30V 0.05V with an approximate charging time of 6-12 hours. The circuit is designed with a steady state charging and control system which automatically regulates the charging process. The circuit we design is near the theory charging for Li-ion battery. For a discharged battery a constant current charge is employed at 1500mA 150mA (the charger indicator light is red). When the charging voltage reaches 4.30V, the battery switches to a constant voltage charge (at this point the battery is approximately 70% charged) and the current gradually decreases. When the battery is sufficiently charged it automatically cuts off the circuit to protect the battery from over charging (the charger indicator light is green). Note: It is not necessary to wait until the battery is completely discharged before charging. Charging can be undertaken whilst the battery is at any capacity and it actually prolongs the life span of the battery if charging is completed prior to complete discharge.
Major Technical Specifications:
1. Input: AC85-265V, 50-60Hz
2. Output: DC4.30 0.05V, 1500mA 150mA
3. Size: 125 x 55 x 80mm; weight: 0.3kg
4. Plug: US, EU, UK or AU standards for different markets
