BMW Motorrad Plus battery charger, Operating Instructions Manual, Page: 14 / 21

12 CHARGING PROCESS
The Plus battery charger switches to sleep
mode to conserve energy. The POWER LED
flashes and
Sleep mode Energy-saving
appears in the display. Pressing any but-
ton will briefly awaken the darkened display
from sleep mode.
A very low current flows from the battery
back to the Plus battery charger, so over a
period of months the battery can become
fully discharged. For float charging, there-
fore, the Plus battery charger has to stay
connected to the electricity supply.
