2. General

Accumulators comprise two electrodes which are placed in an electrolyte; this
makes an accumulator a chemical element. Chemical processes run within such an
element. Since such processes are reversible accumulators may be recharged.
Charging an accumulator requires a so-called charging voltage which has to be lar-
ger than is the celll voltage. Furthermore, this requires to feed more energy (mAh) in
charging than can be redrawn later. This relation between the energy fed and energy
drawn is called efficiency.
The capacity to be drawn, which largely depends on the discharge current, is crucial
for the accumulator condition. The charge which is fed cannot be referred to as a
measure because some part of it will get lost (e.g. is converted into heat).
The capacity indicated by the manufacturer is the maximum theoretical charge volu-
me that the accumulator may deliver. This means that an accumulator of 2,000 mAh
may theoretically deliver a current of 1,000 mA (= 1 ampere), e.g. over two hours.
However, such values are dependent, to a very large extent, on many factors (the
condition of the accumulator, discharge current, temperature, etc.).
The C rate term is very common for chargers. The C rate is the current value which is
normally indicated during charging and discharging. This current value in amperes
corresponds to the rated capacity in ampere-hours; this means that C = 2.0 A for an
accumulator of 2,000 mAh.
Note that the capacity which can be drawn from an accumulator is highly dependent
on the discharge current; the smaller the discharge current is the larger is the capa-
city that can be drawn. This charger, when in the automatic mode, automatically
adapts the discharge current to the instantaneous condition of the accumulator.
If accumulator packs have less than 16 cells this charger starts at a discharge cur-
rent of 1.0 A; 1.0 A is 1C already for an accumulator of 1,000 mAh whereas it is only
C/2 for an accumulator of 2,000 mAh. This is why the 2,000 mAh accumulator will
reach its 2,000 mAh easier than will the 1,000 mAh accumulator reach its 1,000 mAh.

1. Utilisation
Ce chargeur sert exclusivement à la charge des packs d'accus au nickel-cadimium
et au nickel-hydrure métallique qui se compose d'accus en tailles Mono, Baby, Sub-
C et Mignon. Les packs d'accus peuvent se constituer de 1 à 20 cellules. Les packs
d'accus composés d'accus en tailles Micro et Lady, ne doivent pas être chargés
avec ce chargeur ! La capacité nominale de ces types d'accumulateur (indiquée en
mAh ou Ah) doit être entre 500mAh et 20Ah.
Ce chargeur sert exclusivement à la charge des accumulateurs mentionnés ci-des-
sus avec le nombre de cellules correspondant. D'autres types d'accumulateurs et/ou
de packs d'accus avec un nombre de cellules différent ne doivent pas être chargés !
