When charging battery the hydrogen which is explosive is emitted. Therefore before charging: 
    – remove traffic jams (on the served batteries);   – disconnect "weight" (if the battery is charged on the car);   – before connection with the battery (or before a detachment from the battery) disconnect the charger from network. 
  
 Security measures 
   Charge the battery in the ventilated room. 
   The maximum current of a charge should not exceed 5 A in order to avoid explosion.   |
