As the battery pack ages, even if it is looked after, its ca-
pacity reduces such that the full run time will no longer
be reached when fully charged. This does not indicate a
defect.
Rectification
 Charge the battery pack.
 Replace the battery pack.
 Push the battery pack into the mounting
until it latches into place.
 Stop working and allow the battery to cool
down to normal battery temperature.
 Stop working and allow the motor to cool
