Control And Filling Up Of The Electrolyte Level; Inactive Or In Discontinuous Service Batteries - Pegasolift TPL 16 Guía Para El Uso Y El Mantenimiento

CONTROL AND FILLING UP OF THE ELECTROLYTE LEVEL:

Periodically check the level of the battery electrolyte; if it is necessary, execute the filling
up only with demineralised water according to the norms CEI21-5 fascicle 255 taking
into account that:
1) It is absolutely prohibited to make the filling up with sulphuric acid
2) The filling up operation should be executed only after a full charging operation
complete of the equalization phase: a filling up with discharged battery could bring,
at the moment of loading, at leaks of electrolyte.
3) The level should remain only a little over the plate with holes for avoiding sprinkling ;
it is preferred have it a little less in order to avoid leakage of electrolyte with
consequent corrosion of the battery space and of the metallic parts.
4) The corks of the battery should be fixed with care avoiding the contamination of the
electrolyte.
5) It is absolutely forbidden to use water containing chloride, calcium, iron or other
impurities.
To maintain in good conditions the battery it is necessary, every time when distilled
water is added, to verify the density of the acid in the electrolyte liquid.
This control will be executed after a complete load of equalization process and after
letting to pass the time needed for the homogenisation of the solution in the interior of
the element.
After a complete reloading, the density of the acid measured at 30ºC (electrolyte
temperature) should be 1,260 kg/dm3, if the value is more than this; it is opportune to
dilute the electrolyte adding demineralised water.
The density of the electrolyte should be increased by 0,0007 for each degree more than
30ºC; diminished by 0,0007 for each degree under it.
Example:
Indication of density at 45ºC : 1,250; correction (45ºC - 30ºC) x 0,0007 = 0,0105; the
effective value of the density is 1,250 + 0,0105 = 1,2605.
As reference if the density is comprised between 1,260 and 1,20 kg/dm3 the battery
should be deemed as partially discharged; if the density is less than 1,140 kg/dm3,
the battery is completely unloaded.
If, after a complete reloading, the acid density results less than 1,20 kg/dm3, the
battery should be deemed as exhausted and so REPLACED.
In every case is prohibited to add electrolyte liquid to the sulphuric acid.

INACTIVE OR IN DISCONTINUOUS SERVICE BATTERIES

During the periods of inactivity the batteries are discharged spontaneously (self
discharge); the self discharge provokes a sulphation of the poles with a progressive
degeneration of the capacity and efficiency of battery.
If the battery is not used continuously or remains inactive for long periods, submit them
at a refreshing loading at least once a month, this is advisable even if the measurement
of the electrolyte density shows high values. In every case, before to put again in service
a car which remained for a long period of time inactive, execute a complete reloading of
the equalization process, a precise control of the electrolyte density and, if it is
necessary , a filling up with distilled water.
