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.
