reliability
1. Each battery terminal is
connected reliably. (When
battery strings are
powered off, check the
reliability of each terminal
in the order from positive
terminals to negative
terminals.)
2. The tightening torque of
each battery screw meets
the requirements of the
battery manufacturer. (A
torque wrench is used for
checking the torque. After
checking that the battery
screws meet the
requirements, mark the
screws for later check.)
