You
will
need
to
fit
an
Anderson
Style
Connector
to
your
12V
Battery
Charger,
then
connect
it
to
the
RHS
Anderson
Output
Connector.
Note:
Check
the
Polarity
of
your
connections!
Ensure
the
ToughPower
is
switched
ON
,
and
all
other
input
Charging
Sources
must
be
disconnected
from
the
ToughPower.
By
attaching
to
the
RHS
Anderson
Connector
the
internal
electronics
and
microprocessor
will
monitor
the
charging
input
from
the
External
12V
Battery
Charger,
and
display
information
on
the
LCD.
Note:
All
other
input
charging
sources
must
be
disconnected
when
using
an
External
Charger.
Alternatively, you can
open the ToughPower Lid, and attach the External 12V Battery Charger’s
Alligator
Clips directly to the Battery terminals. This
bypasses
the ToughPower’s electronics and therefore the LCD
will
not
display
accurate
information
about
the
battery
state
of
charge.
Note: For this method of charging, all other
input Charging Sources must be disconnected
and all
Power
Outlets
must
be
disconnected
from
the
ToughPower.

Charging
Stages
The ToughPower it is equipped with a built-in integrated multi-stage DC-DC Battery Charger. This section
provides
a
brief
description
of
each
stage.
For
all
Lead-Acid
battery
types
the
charger
will
progress
through
the
following
stages:
For
Lithium
LiFePO4
batteries,
the
charger
will
progress
through
the
following
stages:
●
OFF:
Charger
is
disabled.
●
CHECKING:
In this stage (reduced constant-current/trickle charge), the charger charges the battery
with a reduced constant current. This trickle charge stage occurs for battery voltages between 35%
to
70%
(typical)
of
the
voltage
limit
provided
in
the
Charging
Voltage
Limits
section
below.
