5.2.1 HYDROMETRY
Hydrometry can be made with batteries under charge with a densimeter. Do as it follows :
Put the gun densimeter and take a quantity of electrolyte sufficient to push up the floating;
Keep care the the top of it doesn’t touch the rubber or the glass walls.
For a mesure of density, after filling up with distilled water, density has to be uniform in the box.
5.2.2 WATER FILLING UP
Put distilled water in each cell of the battery before charging the batteries to take the liquid at 6 mm
over the plates.
This operazion has to be made every time the level goes down, but never over a week between two
filling up.
5.2.3 CHARGING LIMITS
It’s not necessary to charge the battery if density, after a working day, is underneath 1,24 (28 Bè). The best
recommended temperature is 45°C. If the electrolyte temperature goes up of 10/12°C inside facing to room
temperature, it can be overcharged without depending from the normal use.
5.2.4 OFF DUTY OR INACTIVE BATTERIES
While inactive, the batteries can go flat by themselves. If battery is not frequently used, it may occurrs to do the
following operations:
Once in a month place it under charge, to a voltage indicated as “final”, until all elements are full of
gas and is possible to read tension and specific weight for 3-4 hours about ;
It’s necessari to do it even when mesurements of specific weight show high values. If battery stays
inactive longer it has to be preserved in a dry place.
5.2.5 TECHNICAL FEATURES OF THE CHARGER
The charger has the following features:
-
Entrance
-
Exit
For that it concerns the technical features of recommended accumulators see Section 2.3
TECHNICAL DATA TABEL.
