Charging Your Battery; State - DieHard 200.71312 Owner's Manual

AMMETER:
The ammeter indicates the measured amount of
amperes being drawn by the battery. When you first
3tart charging a battery, the reading will be high, with
the needle near 12 using the 12 amp charging rate.
• In the MANUAL setting, as the battery charges, the
needle will fall to about 5 to 6 amps, indicating a
charged battery.
• In both AUTOMATIC settings, the needle will fall to
zero and the charger will shut off when the charger's
control circuit senses a full charge. A freshly
charged battery's voltage will drop shortly after
charging, and the charger, if left connected, may
resume charging. This off-and-on cycling will
continue until the battery's voltage no longer drops
enough to restart the charger.
• At the 2 amp charging rate you will notice very little
needle movement.
Nhen cranking the engine while using the ENGINE
START feature, the needle will swing into the Start
(red) area of the scale.
LED INDICATOR:
The green LED INDICATOR wUl glow when the charger
senses that the battery has reached a full charge.
• When using the MANUAL charge rate, stop charging
when the LED glows and the AMMETER needle is
about 5 to 6 amps in the 12 Amp setting.
• For deep cycle batteries, you may wish to allow the
battery another one or two hours of charging after
the LED glows to obtain a maximum charge.

• When using the AUTOMATIC charge rates, the LED

taining the battery's state of charge.
Charging Your Battery
Charging a battery in the vehicle:
1. Arrange the power cord and charging leads carefully
to avoid damage that could be caused by the hood,
door, or moving engine parts.
2. Keep clear of fan blades, belts, pulleys, and other
parts that can cause injury.
3. Check the polarity of the battery posts as indicated
on the battery case: POSITIVE (POS, P, or +) and
NEGATIVE (NEG. N or -). NOTE: The positive post
on top-post batteries is usually larger than the
negative post,
4. Identify which battery post is ground or connected to
the chassis. THE NEGATIVE POST IS
NORMALLY THE ONE THAT IS GROUNDED,
5. To charge a negative grounded post system:
Connect the red (POSITIVE) battery charger clamp
to the ungrounded POSITIVE (POS, P, +) post of
the battery. Then connect the black (NEGATIVE)
clamp to a heavy, unpainted metal part of the
chassis or engine block, away from the battery. Do
not connect clamp to carburetor, fuel lines, or sheet
metal parts.
