3.1 Charging
During charging, the LED lights red.
At the end of the charging cycle the LED lights green.
The battery capacity can be read by pressing the thickener in the foil. One,
two or three green LEDs will light up as a rough indication of the charge
status. When the battery is empty, a small red LED lights up.
Never charge the battery pack at temperatures below 0°C. At -10°C, a
protection device is activated which makes charging impossible. The
battery can be discharged or used up to a temperature of -20°C.
