equipment and electric power systems. These energy sources
are extremely easy to maintain and very reliable. Even so, there
are a number of basic rules which must be observed when hand-
ling these batteries; keep to the rules, and they will reward you
with a long useful life and maximum possible capacity.
The POWER-PEAK INFINITY 2 ia also an excellent choice for
charging modern nickel-metal-hydride (NiMH) batteries. In futu-
re these batteries are likely to become more and more popular
as they offer significantly higher capacity for a given wight and do
not contain any cadmium, which is a highly toxic heavy metal.
A new battery, or one which has not been used for a long time,
must be slow-charged before use. The same applies to a pack
which has been deep-discharged, in which case one or more
cells may have suffered polarity reverse. A slow charge means a
period of about 24 hours at a current corresponding to 10% of
the nominal capacity (charge rate 0.1 C).
We have to differentiate between normal (slow) and rapid char-
ging of NC batteries. The standard charge rate (C) is now in
Operating instructions
POWER PEAK INFINITY 2
Rapid charge output for charging and discharging 1 to 30 NC or NiMH battery cells, or 2 to 12 V lead-
acid batteries.
Charge output for 4-cell to 8-cell receiver or transmitter batteries.
The screen displays the parameters you have set, and also shows the actual values during charge
and discharge processes. The screen is backlit, which means that it is easily legible in the dark, e.g.
when using the charger under the opened car bonnet. It also features a particularly wide effective
viewing angle of almost 45°.

general use to define charge currents and discharge currents
related to battery size: it represents the relationship between the
charge current and the battery capacity. For example, if you want
to charge a battery with a capacity of 600 mAh using a charge
rate of '1 C', then you must set a charge current of 600 mA.
The term slow (or normal) charging covers the charge rates 0.1
- 0.2 C.
An accelerated charge involves the use of a charge current of
0.3 - 0.5 C. The term rapid charging is generally applied to any
process in which the charge current is higher than those already
stated. If you wish to use a charge rate higher than 0.1 C, the
charge process must be carefully monitored and switched off at
the correct time, i.e. as soon as the pack is fully charged. This in
turn calls for the use of a charger such as the POWER PEAK
INFINITY 2 , which is capable of switching off the charge current
automatically when the pack is full.
NiMH batteries must not be charged at a rate higher than 1C. For
example, a NiMH drive or flight pack with a nominal capacity of
3,000 mAh should be charged at a rate no higher than 3 A. At this
