Charging NiCd batteries
does not necessarily
require a complex
design. The
charger described in
this article shows that
a reliable unit with
built-in timer can be
constructed for a relatively
small outlay.
I N T R O D U C T I O N
Over the years many techniques have
been developed for fast, accurate and
reliable charging of NiCd batteries.
One of the best of these is still the
14-hour method at one tenth of the
battery capacity. The present design
contains a adjustable current source
and a timer which, after normal charging
has taken place for 14 hours,
switches the charger to trickle charging.
Since the current source is
adjustable, the charger may be used
with a wide variety of NiCd batteries.
