The battery discharges too fast
during use, recharging with an
electronic battery charger is
too fast and after recharging
the battery supplies the right
voltage (about 2.14V for each
element without load), but
when tested with a hydrometer
is found not to be uniformly
charged
• the battery supplied filled with
acid by the Manufacturer has
been stored for too long before
being recharged and used for
the first time
• if recharging with a normal
battery charger is not
effective, you must use a
double recharging cycle:
- charge slowly over a 10 hour
period at a current of 1/10 the
nominal capacity for 5 hours
(e.g. for a 100Ah(5) battery
the current must be set at
10A, using a manual battery
charger);
- rest for one hour;
- charge with the normal
battery charger.
At the end of charging with the
electronic battery charger, the
battery does not provide the
correct voltage (about 2.14 V
per element without load) and
appears to be uniformly not
charged when tested with a
hydrometer
• the battery has not been
connected to the battery charger
(for example, because the low
voltage connector of the battery
charger has been erroneously
connected to the machine
connector)
• connect the battery charger
to the battery connector
• the battery charger and power
socket to which the battery is
connected are not compatible
• check that the power supply
characteristics indicated on
the battery charger rating
plate comply with those of the
mains power supply
• the battery charger has not
been installed correctly
• taking the actual voltage
available at the socket into
account, make sure that the
connections of the primary of
the transformer inside the
battery charger are correct
(consult the battery charger
manual)
• the battery charger is not
working
• make sure there is voltage to
the battery charger, that the
fuses are not blown and that
the current reaches the
battery; try charging with
another rectifier. If the battery
charger is not working,
contact the technical service
centre and indicate the serial
number of the battery charger
At the end of charging with the
electronic battery charger, the
battery does not provide the
correct voltage (about 2.14 V
per element without load) and
only one or a few elements are
found to be discharged when
tested with a hydrometer
• one or more elements are
damaged
• replace the damaged
elements if possible.
For 6 or 12 V single block
batteries, replace the entire
battery
The electrolyte in the battery is
turbid
• The battery has reached the
end of the charging/discharging
cycles declared by the
manufacturer
• replace the battery
• the battery has been recharged
with too high a current
• replace the battery
