BATTERIES
CHECKING THE CHARGE STATE OF THE BATTERIES
As it is known that there is a direct relation between the specific gravity of the electrolyte and
the charge state of the battery, the measure of the specific gravity of the electrolyte is
assumed to be an efficient and correct control of the battery charge state. When the battery
is charged and is under normal conditions, with the electrolyte located at the proper level,
the electrolyte density will be about 1.260 (30°Bè) referred at 30°C. If density is between
1.26 (30° Bè) and 1.20 (24° Bè), the battery is partially discharged, but if density is lower
than 1.14 (18° Bè), the battery is completely discharged.
DENSITY MEASUREMENT
The density measurement of the electrolyte is the most important check on a battery. This
measure should be performed with extreme caution by means of a densimeter. The syringe
densimeter should be introduced, thus extracting an amount of electrolyte enough to bring
the float on the surface. The float top should neither get in touch with the rubber pear nor
be stuck with capillarity to the glass walls. Should a density measure be performed after ha-
ving added some distilled water, wait until the density has become homogeneous in all liq-
uid contained in the element.
WATER TOPPING UP
Add some distilled water in each battery cell, after charging the batteries, to bring the liquid
to a level of 6 mm over the plates. The operation will initially take place after each charge,
then the subsequent toppings up can be executed less frequently, according to the expe-
rience of the person responsible of it, but never let more than one week between one top-
ping up and the next.
