prolonged use will reduce the life expectancy of the battery, due
to the fact that this method can only charge the battery to
approx. 50% of its capacity.
NOTE: For maximum battery life, we strongly recommend that you
maintain the battery in a fully charged state at all times.
NOTE: If charging does not take place, check the green LED on the
adapter. Ensure all connections are clean and free of grease etc.
