Operation with rechargeable batteries
Rechargeable batteries will run down even during prolonged idle periods if the scale is not
connected to the mains. Therefore, connect the scale to the mains at least every 3 months.
When the scale is operating on the mains supply, the rechargeable batteries are only
recharged when the scale is switched on (trickle charging).
Overloading the batteries is prevented automatically by an integrated charging circuit. This
charging circuit also prevents any damaging total discharge. The battery lifetime reduces if
it is permanently operated at an almost discharged state.
_______________________________________________________________________
Battery lifetime
− Rechargeable batteries have a limited lifetime.
As a result the capacity of the batteries decreases, as does the
serviceable life of the scale in rechargeable battery operation.
− New rechargeable batteries must be fitted in order to return the scale
to full power in battery operation.

Battery charging functions
The rechargeable batteries are charged during mains operation, but
only when the scale is switched on. There are 2 charging functions for
charging the batteries. These can be selected in menu Pr532:
− Charging new batteries
New batteries require two trickle charges of 16 hours each.
To do this, select Pr532=02 in the menu.
Automatic charging is reselected after each trickle charge.
− Automatic charging
The batteries are automatically charged through internal
measurement of the charging condition in the scale.
