Charging Batteries - Kompernass Tronic KH 967 Operating Manual

4. Charging batteries

Danger: Only charge batteries identified by the letters
"Ni-Cd" or "Ni-MH" .
Never charge other types of batteries, even if these
are "rechargeable". Such batteries require a quite different
type of technology!
If you place these batteries in Ni-Cd/Ni-MH battery
chargers, they can overheat and explode.
a) Inserting batteries
• Place the batteries the right way up, as indicated in the
charging slots. Otherwise the charging process cannot
start.
Ni-Cd batteries should only be recharged when they are
almost completely discharged. Otherwise, a "memory
effect" is created, where the batteries reduce their
capacity to the lower level at which they are actually
used. Ni-MH are not susceptible to the "memory effect".
b) Test the batteries first!
If you do not know how charged or discharged your
batteries are, you can test them as follows:
Move the switch to the far left, to the position with
the "Test" symbol.
The test indicator light at the symbol
if the battery is sufficiently charged. If the test indicator
light is lit only faintly or not at all, then the battery is
almost completely discharged or flat.
Note: Only insert the battery in the slot on the far left is
tested. If you would like to test the other batteries as well,
they must be inserted one after the other into this slot.
The test function is not available for 9V single block
batteries!
