Battery exploitation induction is happening as follow:

• check of completion and existence of mechanical damages
• cleaning and possible drying of the battery
• checking connection attachments
• removal of transport pockets
• checking  stagnancy status and density of electrolytes
• if required implement first charging of the battery
  

(1.28 +0.02,-0.01)kg/l on 25°C.

Batteries, or panels configured for exploitation in warm/tropical climate environments, must have letter T added. In this type of batteries density of sulphuric acid inside the battery or panels when filled, needs to be:

(1.23+0.02,-0.01)kg/l on 25°C.

For soaking dry, filled,undried batteries and panels, sulphuric acid is used of certain quality and per standard JUS H.B.013. and with followed density:   

(1.28+0.01,-0.01)kg/l on 25°C  for average and cold climate environments. (1.23+0.01,-0.01)kg/l on 25°C  for warm/tropical climate environments.
