Are
you tired
of waiting
for
numerous
hours to
have your
batteries
recharged?
Do you
have a
collection
of various
sizes of
rechargeable
batteries?
Would you
like a
charger
than can
discharge/recondition
your
‘dead’
batteries?
If your
answer is
a yes
for the
above,
then look
no further
as this is
possibly
the only
charger
you will
ever need.
The
Intelligent
Charger
(IC) is a
state-of-the-art,
microprocessor
controlled
charger
for
charging
rechargeable
Nickel
Cadiums
(Ni-Cds)
and Nickel
Metal
Hydrides
(Ni-Mhs).
It is able
to detect
the
current
state of
the
rechargeable
battery
and
recharge
it to the
full
capacity
appropriately,
irregardless
of the
brand and
the
capacity
of the
battery.
It does
this
without
overcharging
or
damaging
the
battery.
–dV
is used to
control
the
charging
of Ni-Cds
while +dV
is used
for Ni-Mhs.
Unlike
conventional
time-based
chargers,
it cannot
be easily
fooled. It
will not
charge
batteries
that are
already
fully
charged.
Overcharging
will
shorten
the life
cycle of a
battery
and may
even cause
permanent
damage to
it.
By
pressing
down on
the switch
in the
center,
the smoked
cover
springs up
(damped
action
adds a
classy
touch to
it) to reveal
a
well-designed
battery
compartment
that
supports
AAA, AA,
C, D (the
2 sides)
and
9-volts
rechargeable
batteries
(center).
At any one
instance,
it can
recharge
two
batteries
of the
same
category.
For the
cylindrical
rechargeable
batteries,
the IC
uses a
fixed
contact
point for
the anode
and a
retractable
contact
point for
the
cathode so
that it
can
accommodate
all sizes
ranging
from AAA
to D.

proceeding

Unlike
many of
the usual
chargers,
the IC is
equipped
with a
separate
power
adaptor.
It means
that this
IC can be
used
practically
in any
part of
the world,
by simply
using the
appropriate
adaptor.
If you
have an
unused
AC/DC
adaptor
that
matches
the above
specifications,
it can
probably
be used as
well.
800mA
is an
impressive
figure for
the charge
current
specification.
This is
the
highest
figure I
have ever
come
across for
a
cylindrical
dry cell
charger!
It is a
breeze to
recharge
batteries.
As a
reference,
a table
has been
included
in the
operating
instruction
manual for
an
estimation
of the
charge
time
required.
I have
included
the table
for your
reference.
Check it
out!

Try
comparing
the above
charging
times with
your own
existing
charger
and you
will
appreciate
the
difference.
It can be
seen from
the table
that 9V
rechargeables
require a
notably
longer
period to
charge.
This is
because
the unit
only uses
a
continuous
trickle
charge
mode for
charging
9V
batteries.
I was told
that this
is due to
some
technical
limitations
associated
with 9V
rechargeable
batteries
and they
cannot be
fast
charged.
