Deviations in electrolyte density
Deviations in electrolyte density
  Note
t  The maximum permissible differences (deviations in electrolyte density) between the cells must not be greater than/same as 0.04 kg/dm3.
t  The electrolyte density must be at least 1.24 kg/dm3.
Examples of unacceptable deviations in specific gravity:
   
Specific gravity deviations in kg/dm3 per cell
Example 1:1.241.251.251.101.241.25
Example 2:1.261.261.251.141.181.24

Deviations in electrolyte density in Example 1, cell 4 (1.10 kg/dm3), as well as Example 2, cell 4 (1.14 kg/dm3 ) and cell 5 (1.18 kg/dm3 ) are not permitted. The batteries shown in the examples are no longer usable and must be disposed of.
The following values must be attained:
   
Charge condition in normal climatic zonesSpecific densities in kg/dm3
Discharged1.15
Half charged1.22
Well charged1.28

  WARNING
Always use genuine sealing plugs in battery openings to guarantee the sealing of the various battery cover systems. Only use genuine sealing plugs of same construction if lost or damaged.
The plugs must be equipped with an O-ring seal.
