The batteries do
not provide the
normal work
time (battery
models only)
the battery poles and charging
terminals are dirty and oxidised
clean and grease the poles and
terminals, recharge the batteries
the electrolyte level is low
top up all the elements with distilled
water as described in the instructions
the battery charger does not work or is
unsuitable
see battery charger instructions
there are considerable differences in
density between the various elements
of the battery
replace the damaged battery
you are using the machine with
excessive pressure on the brushes
reduce pressure on the brush
there are considerable differences in
density between the various elements
of the battery
replace the damaged battery
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
recharge 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
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.
