Warning! Please remember that the battery contains sulfuric acid solution (electrolyte) – an aggressive, highly toxic substance that corrodes skin and clothing and causes severe corrosion and oxidation of most metals. If sulfuric acid gets into your eyes, rinse the affected areas with plenty of water. If sulfuric acid gets into your eyes, seek medical attention immediately.
When charging the battery (by car or indoors) oxygen and hydrogen are released. The gases are released most intensively at the final stage of battery charging, the amount of gas released is proportional to the value of the charging current.
Oxygen and hydrogen mix at the surface of the plates and form an explosive mixture.
The slightest spark from a lit cigarette or a match that has just gone out is enough to cause an explosion. The battery is destroyed and sulfuric acid is thrown out. People nearby may be injured by fragments of the battery case or splashes of sulfuric acid. The latter are especially dangerous if they come into contact with the eyes, face or hands. In addition, clothing is damaged.
Before disconnecting or connecting the battery, turn off all power consumers.
When charging the battery indoors, be sure to turn off the charger before disconnecting or connecting the battery.
Do not place metal objects on the surface of the battery that may cause a short circuit between the battery terminals.
Do not bring open flames, blowtorches, gas burners, lit cigarettes or matches near the battery.
