6. General information
Rechargeable batteries consist of two electrodes that are placed into
an electrolyte. Batteries are therefore classed as a chemical element.
Chemical reactions take place inside this element. These reactions are
reversible, which makes it possible to recharge the battery.
A charge voltage is required to recharge batteries. This voltage must
be higher than the cell voltage. Moreover, the energy (mAh) supplied
during the charging process must be higher than that which can be
drawn afterwards. This ratio of the energy supplied to the energy drawn
is called efficiency.
The capacity that can be drawn mainly depends on the discharge
current and has a decisive impact on the condition of the battery. The
supplied charge cannot be used as a measure, because some of it will
be lost during charging (e.g. converted into heat).
The capacity data given by the manufacturer is the maximum theoretic
quantity of current which can be delivered by the battery. This means
that a 2000 mAh battery can, for example, theoretically deliver a
current of 1000 mA (= 1 A) for two hours. This value depends heavily
on numerous factors (e.g. condition of the battery, discharge current
and temperature).
• Do not attempt to recharge disposable, non-rechargeable
batteries. This may cause a fire or explosion! Only
recharge batteries that are marked as rechargeable.
• Always observe the correct polarity (positive/+ and
negative/-) when inserting batteries into the charger.
• This product is only suitable for NiCd, NiMH, Li-lon,
LiHv, Ni-MH, Ni-Cd, NiZn, LiFePO
batteries.
