e) Subsequently changing the operating mode or charging current
for all battery slots
• Press and hold the "MODE" key (6) for approx. 1 second. The operating mode ("CHARGE" or
"CHARGE TEST") flashes on the LC display.
• Select the operating mode by briefly pressing the "MODE" key (6).
• Change the charging current by briefly pressing the "CURRENT" key (4).
• Wait a few seconds, the settings are applied.
f) Switching display indicators
By pressing the "DISPLAY" key (5) repeatedly, you can display various data on the display dur-
ing the charging/discharging process (if the data for only one battery slot is required, select the
battery slot beforehand with the "1" to "4" control key so that the indicator flashes).
• Battery voltage (V)
• Charging current (mA)
• Charged capacity (mAh)
• Elapsed charge/discharge time (h; displayed in HH:MM, hours:minutes)
If a duration of 20 hours has been reached and exceeded, the indicator will start again
at "0:00".
• Internal resistance (mR, milli-ohm); a low internal resistance indicates a high-quality battery
cell; an increasing internal resistance for a battery may be a sign of ageing
10. USB output
The USB output (9) on the rear of the charger can be used, for example, to charge a smart-
phone. The USB output has a usual voltage of 5 V/DC; it provides a current of up to 1 A.
