  • Discharge Characteristics
    Discharge capacity varies depending on discharge current(hourly rate). The smaller the discharge current, the more capacity increases, and the large the discharge current, the lower the capacity. Figure shows the constant current discharge characteristics of batteries when discharged, to the final discharge voltage, at various discharge currents.


  • Constant Voltage Cccharging
    Charging at constant voltage is the most suitable and commonly used for charging DW batteries Figure 10~15 shows the charging features of DW batteries when charged with constant voltage chargers at 2.23volts/cell, 2.30volts/cell, 2.40volts/cell and 2.50volts/cell, with the initial charging current controlled at 0.1CA and 0.25CA.

Battery Life

  • Cyclic use
    The cyclic life is very much dependent on the depth of discharge which the battery expedites during each cycle. The number of cycles, varying with the depth of discharge are shown in the graph.
  • Floating Use
    Floating use is very much dependent on the temperature at which the battery is floatably charged. Float life is very long at low temperatures(10~20°C) but is shortened at higher temperatures.
