If batteries are not to be used for a while, the following
must be observed when storing them:
Disconnect the negative battery connection on the
battery and store it so that it cannot inadvertently
come into contact with the negative terminal of the
battery.
Only store batteries while charged.
The storage location should be cool (the self-dis-
charge rates will be lower).
Maintenance-free batteries:
Carry out the monthly voltage test.
Recharge once the battery capacity is lower than
60%.
Discharge end voltage or total discharge protection:
The settings of the discharge end voltage must be
checked to ensure that the runtime of the machine is
not limited and that the battery cannot deeply dis-
charge.
Connect the charger to the batteries.
Connect the voltage meter and clip-on ammeter to
the batteries.
Insert the power cord of the charger into the sock-
et and turn the charger on.
Determine the current and voltage measuring val-
ues after switching on the charger and record
them.
Determine the current and voltage measuring val-
ues after about 10 minutes and record them.
The measuring result of the I constant phase in the
main charge must be close to the manufacturer's
values of the charger. (See typeplate of charger.)

IUIa means:
I = constant current line
U = constant voltage line
I = constant current line recharging
a = automatic switch-off (transition to maintenance
charge)
During the I constant phase, the charger is
charged with the nominal current (see typeplate
on charger) and the charge voltage will increase
slower or faster depending on the charge condi-
tion. After that, the charger will switch to U con-
stant phase.
In the U constant phase, the voltage remains con-
stant and the current sinks continuously. After
that, the charger will switch to I constant phase.
In the I constant recharging phase, the voltage will
rise to the values indicated in the diagrams and
the current remains constant. After that, the charg-
er will switch to maintenance charge.
The recharging phase serves to achieve the com-
plete transformation of the active mass in all bat-
tery blocks.
During the maintenance charge, the fully charged
battery status remains at constant voltage. The
maintenance charge has no time limits.
