Operating Instructions
OPERATION
a) Open plugs.
b) Pour in the electrolyte at a temperature
between 15¯ and 30¯ C, at a density of
1.270 1.280 kg/l. Make sure the level of
the electrolyte is between 5 _ 7 mm
above the height of the separators in
each cell.
c) After approximately one hour, if necessary,
top up the electrolyte level again, as it
may have been partially absorbed by the
plates.
d) Connect positive and negative poles to
the rectifier. Make sure the polarity is
correct.
e) Let the battery rest for about 4 hours,
then charge at a current intensity about
1/10 of the rated capacity of battery,
proceeding for the time required to reach
a voltage of about 2,7 V in each cell, and
a density of 1.280 1.290 kg/l at 25¯ C
(approximately, from 5 to 15 hours, at
most. For example: 24V - 480 Ah battery
charging current 48 A).
f) The battery temperature must never
exceed 45¯ C during charging. If this
threshold is exceeded, gradually reduce
the current intensity until an acceptable
temperature is reached (around 30¯ C).

g) When charging is finished, the density of
the electrolyte must be the same for each
cell, and be between 1,280 1,290 kg/l,
at 30¯ C.
h) Leave the plugs open during charging of
the battery in order to allow any gasses
to dissipate (oxygen and hydrogen).
i) Close the plugs and clean the upper part
of the battery carefully.
l) The temperature of the environment affects
the density of the electrolyte.
m) The temperature of the environment
affects the Ah capacity supplied by the
battery. Every increase or decrease with
respect to 30¯ C affects the performance
of the battery.
