(1) Presence of impurity in the electrolyte (2) Short circuit of the external circuit of the battery (3) Spillage of electrolyte on the surface of the battery caused a short circuit of the anode and cathode terminals (4) A metal tool or lever part is located between the anode and cathode terminals, this caused a serious short circuit (5) Peeling of active substances on the plate, the deposition level is too high, this caused short circuit of the plate; damage to the septum caused a short circuit of the plate; plate drive caused a short circuit of the plate
(1) If required, add electrolyte prepared with chemical pure sulfuric acid and distilled water (2) Check the circuit in which the short circuit occurred, eliminate the faults (3) Clean the surface and cap of the battery with lye or hot water so that its outer surface is clean (cannot get into the battery) (4) Do not put metal lever part or tool on the surface of the battery (5) Repairing or replacing the battery
