Battery Remaining Power
The battery remaining power is
enough.
The battery remaining power
is a half.
The battery remaining power is
nearly empty.
Re-charge the battery soonest
possible.
NOTE
The use of the battery in a cold condition (below
0 degree Centigrade) can sometimes result in the
weakened tightening torque and reduced amount of
work. This, however, is a temporary phenomenon,
and returns to normal when the battery warms up.
