Some types of rechargeable batteries tend to partially lose their capacity if they have rest capacity when being recharged. This is especially true for NiCd batteries which are being used in RCS Plus and RCS High Flow air samplers. The so-called "memory-effect" can be largely averted by discharging NiCd batteries before recharging. In case a memory-effect already occured multiple discharging helps to reduce the effect.

Handling:

The RCS Discharger can handle batteries with voltages of 7.2 V (article no. 940 375 for RCS Plus/RCS Plus Ex) and 9.6 V (article no. 940 275 for RCS High Flow). While inserting batteries into the discharger one has to make sure that the +/- marks point to the corresponding marks on the instrument.

During the discharging process the LED on the left side of the discharger indicate the function status:

• upper LED while discharging 9.6 V batteries
• middle LED while discharging 7.2 V batteries
  

Discharging a fully charged battery takes 60-80 minutes, rest capacities less accordingly.

Technical Data:

• Nominal voltage: 7.2 V or 9.6 V
• Maximum voltage: 9.0 V or 12.0 V resp.
• Cell capacity: 1300 mAh - 1900 mAh, typically 1400 mAh
• Discharging time: 60-80 minutes at 9.6 V
• Output: 12 W
