The battery discharges too fast
during use, even though it has
been charged correctly and
when tested with a hydrometer
at the end of recharging, it
turned out to be uniformly
charged (battery models only)
• the battery is new and does not
deliver 100% of its expected
capacity
• the battery must be "run-in"
by performing 20-30 charges
and discharges to obtain
maximum performance
• the machine is being used at
maximum capacity for
continuous periods and the
working time is not sufficient
• if possible, use batteries with
a higher capacity or replace
the batteries with others
charged previously
• the electrolyte has evaporated
and does not cover the plates
completely
• top up all elements with
distilled water until the plates
are covered then charge the
battery
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 (battery models only)
• the battery supplied filled with
acid by the Manufacturer has
been stored for too long before
being charged and used for the
first time
• if recharging with a normal
battery charger is not
effective, you must use a
double recharging cycle:
- charge it 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 it 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 (battery models
only)
• 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
