Lead-acid batteries without a battery box will not “explode”, but the reason why the battery will “explode” after being installed in the battery box is because:

1) The power supply box is too sealed, and the hydrogen generated at the end of the battery charging cannot escape;

2) The power connection line is loose, aging or exposed, sparks are generated when the key is turned on, or the line generates sparks to ignite hydrogen due to uneven road vibration;

3) The fuse holder on the power box body is loose, and it generates heat or sparks during the charging and discharging process of the battery, ignites the hydrogen gas to produce gas expansion, and breaks the upper cover of the battery;

Preventive measures:

1) The power box should not be too sealed during design. Several convection vents with a diameter of about 1cm should be provided on the upper and lower parts of the battery box to facilitate the discharge of gas generated during charging;

2) If the power box is designed without ventilation holes, the ventilation holes must be reserved during installation;

3) Regularly check the power wiring to prevent loosening, aging or exposure;

4) If the fuse holder is found to be loose and aging, replace it in time.
