rate the charge period is around 1.2 hours. When charging NiMH
batteries it is essential to ensure that the charge current is inter-
rupted immediately when the pack is full, otherwise the cells may
suffer permanent damage. If overcharged these cells become
dangerously hot; the maximum permissible temperature of a
NiMH pack after a charge process is 40°C. This requires the use
of a battery charger with a highly accurate charge termination cir-
cuit. The POWER PEAK INFINITY 2 fulfils these criteria com-
pletely, provided that the termination sensitivity is set to "sensiti-
ve", and the trickle charge current is set to 0 mA.
The best known method of charge termination is the Delta Peak
principle. This requires the charger to monitor the voltage of the
battery constantly, so that it can detect when the pack is fully
charged and switch off the current at that point. Not all NC bat-
teries are capable of being rapid-charged. This applies in parti-
cular to the packs used for transmitter and receiver batteries,
which generally consist of cell types which are optimised for
maximum capacity. The maximum charge current for this type of
battery is limited to a fairly low level.
Before you set the charge current it is important to check that it
does not exceed the limit for the type of battery in use.
Nickel-Cadmium batteries lose about 1% of their charge every
day, which means that a fully charged pack will be completely flat
after about 100 days in storage. NiMH batteries self-discharge at
a rate of 2-3% per day, and will therefore be completely flat after
35 - 40 days. This characteristic clearly implies that batteries
must be charged up before each session.
If you know that you will not use a particular battery for a long
period, it is better to discharge it and then store it in cool, dry con-
ditions. It can then be restored to almost full capacity simply by
balancing the pack, i.e. giving it a single slow charge.
When using NC cells a number of safety measures must be
observed, otherwise you run a real risk of causing personal injury
and damage to property.
- battery cells must never be brought into contact with open
fire, as they may explode.
- Never forcibly open battery cells as they contain corrosive
chemicals.
- Never short-circuit the terminals of battery cells; fire and
explosion hazard.
- A charged battery pack is not a toy. Keep such batteries well
out of the reach of children.
NC batteries constitute toxic waste, and you should never dispo-
se of them in the ordinary household rubbish. If you have a faul-
ty or exhausted pack, discharge it completely, then hand it in to
your local collection point in order to protect the environment.
This can be your local toxic waste collection centre or any bat-
tery dealer. These dealers are obliged to accept batteries
whether you purchased them there or not.
The batteries are then re-cycled, and the material is returned to
the production process. Thus the toxic heavy metal does not
reach the environment, and you have made your contribution to
environmental protection.

5. The charger in use

When you wish to use the POWER PEAK INFINITY 2 it is very
important to keep to the sequence of operations described
below:
- First connect the crocodile clips to a 12 V lead-acid battery.
Take great care to maintain correct polarity (red = positive,
black = negative). The screen should now display the mes-

6. The menu structure of the INFINITY 2

Before you start charging or discharging a battery, you should
make yourself familiar with the charging station's menu structu-
re. The first step is always to select the correct mode of operati-
on for the process you wish to carry out.

Modes of operation

As mentioned in the earlier explanation of the charging station's
controls, the 'MODE' button is used to select the mode of opera-
tion before you start to use the charger. The following modes are
available:
CHARGING MODE:
DISCHARGING MODE:
CHAR => DISC MODE:
DISC => CHAR MODE:
LEAD BATTERY:
Each of the POWER PEAK INFINITY 2 's operational modes
has an associated screen display which appears for a short peri-
od after you press the 'Mode' button to select a new mode.
Examples of these displays are shown in the detailed explanati-
on of the individual operational modes. It is not possible to alter
the mode of operation while a charge or discharge process is
actually in progress.

either you have connected the crocodile clips with reversed
polarity, or the input voltage is too low.
Connect the charge lead to the banana sockets on the char-
ger, taking care to select correct polarity (red = positive /
black = negative). Now connect the NC battery with correct
polarity. Caution: read the notes regarding IEC requirements.
