Safety rules for the battery
The electrolyte of a battery contains sulfuric acid,
which can produce flammable and explosive
hydrogen gas. Incorrect operation can cause serious
injury or fire, so the following precautions must be
followed:
● Regularly check the electrolyte level of the battery
and replenish it with distilled water, so that the
electrolyte level is between the "upper level" line and
the "low level" line. If the battery electrolyte is lower
than the "low level" line, do not use the battery or
charge the battery.
● When operating the battery, wear safety glasses and rubber gloves.
● Smoking or open flames are not allowed near the battery.
● If sulfuric acid splashes on eyes, clothes, or skin, immediately rinse with plenty of water
and seek medical attention.
● Before operating the battery, turn the key switch to the OFF position.
● Check the electrolyte level with a flashlight, and turn off the engine when checking.
● The expansion of the closed end of the battery indicates that the battery has frozen. When
the battery freezes, do not charge the battery or jump start the engine.
Do not heat a frozen battery above 15
℃
, otherwise the battery may explode.
Explosion prevention of the battery
Warning: Electric sparks or flames can cause hydrogen gas in the battery to
explode. To prevent explosion, please note:
1) To disconnect the battery cable, the negative (-) cable should be
disconnected first;
2) To connect the battery cable, the negative (-) cable should be connected
finally;
3) Do not short circuit the terminals of the battery with metal components;
4) Do not weld, grind, or smoke near the battery.
Due to the risk of sparks, follow the below steps.
● Firmly install the battery in the designated position.
● Do not allow tools or other metal objects to come into contact between the battery
terminals. Do not leave tools or other metal objects near the battery.
● Connect or disconnect the positive and negative poles of the battery in the correct order.
The battery terminals should be securely fixed.
● When charging a battery, flammable hydrogen gas will be generated. Therefore, before
charging, remove the battery from the lower body of the vehicle, place it in a well ventilated
area, and remove the battery cover.
● Tighten the battery cover firmly.
Attention: When repairing electrical systems or welding, it is necessary to remove the
negative terminal of the battery to prevent the current flow.
