Discharging / Balancing Batteries; Discharging Mode - ROBBE POWER PEAK INFINITY 2 Notice D'utilisation

Please note that the potential maximum charge current of 5 A
varies according to the number of cells in the pack (see
Specification).
A pack which is already fully charged will have a high internal
resistance, and in automatic mode it will only be charged at a
very low rate.
If you encounter problems when attempting to use automatic cur-
rent setting with some older types of battery, we recommend that
you charge them with a manually set current.

The procedure for setting up the POWER PEAK INFINITY 2

discharge voltage, or simply select the automatic mode. Please
observe the permissible currents stated by the battery manufac-
turer.
The discharge current can be selected within the range 0.1 A to
5 A. It is important to check that the cable conductors and the
connectors fitted to the transmitter and receiver batteries can
cope with the discharge currents you intend to use.
A useful guide value for final discharge voltage is 0.85 V / cell.
Press the 'START-STOP' button to start the discharge process.
The end of the discharge process is indicated by an appropriate

You can also manually interrupt the discharge process at any
time by pressing the 'START-STOP' button.

This value can be used as an accurate basis for drawing conclu-
sions about the general condition of a pack, and allows you to
check the state of your batteries at regular intervals.
As with charging, you should not disconnect the battery when it
is being discharged without first pressing the 'START-STOP' but-
ton, otherwise you will see the corresponding error message.

The measured values, e.g. the discharged capacity, are stored
by the charger after you disconnect the battery, and are retained
until either you disconnect the charger from its power supply, or
you connect a new pack to it.
As in the case of a charge process, the variable parameters you
have set for a discharge process are retained even after the
power supply voltage is disconnected.
Please note also that the maximum discharge current varies
according to the number of cells in the pack. The POWER PEAK
INFINITY 2 's software ensures that the maximum discharge
power (see Specification) is not exceeded.
The POWER PEAK INFINITY 2 provides facilities for maintai-
ning NC packs, i.e. for balancing new batteries, and also for revi-
ving the performance of old packs.
This is the purpose of the two operational modes 'CHAR-
GE=>DISCHARGE' and 'DISCHARGE=> CHARGE'.
In 'CHAR=>DISC' mode the battery is first charged and then
the discharged, in order to balance the state of charge of the cells.
