Precautions

During the discharge of the Heavy Duty Jump
Starter Pack, there is polarization, and the larger the current, the greater
the polarization. The same current, the higher the temperature, the smaller the
polarization. Therefore, the battery should be given a good temperature
environment to ensure high power output to start the motor.

When you can't hit it for the first time, don't
fight immediately. Because of the polarization, the Heavy Duty Jump Starter
Pack voltage has not fully recovered, and it is easy to damage the battery when
it continues to play, and it affects the high current output. Therefore, it is
recommended that the interval between each start is about 10 seconds. Don't be
too fast or too slow.
