    3. Warnings and safety notes · Never leave the charge unsupervised when it is connected to its power supply. If any malfunction is observed please terminate the process immediately and refer to the Manual. · Keep away the unit from dust, damp, rain, heat direct sunshine and vibration. Do not drop it.
  • Page 6 Discharge · The typical purpose of discharge is to confirm the residual capacity of the battery or to lower the voltage of battery to a defined level. When you discharge the battery you also have to pay attention to the process. To avoid over-discharging, please set the nominal discharge voltage correctly.
