(2) Don't let the battery get close to open flames (matches, lighters, lighted cigarettes, etc.). ), and don't cause sparks because of short circuit of wires near the battery.
(3) The electrolyte (dilute sulfuric acid) of the battery is corrosive and cannot be directly contacted. Once the eyes, skin and clothes are stained with electrolyte, please wash them thoroughly with water immediately. If the electrolyte enters the eyes, you should go to the hospital for necessary treatment in addition to washing with water immediately.
