Operating Instructions - DieHard DH138 Manual Del Usuario

NOTE: During charging, the display will
go into sleep mode and will not show the
percentage of charge or voltage of the
battery. To turn the display back on, press
any button.
BATTERY % –
The digital display shows an estimated
charge percentage of the battery
connected to the charger's battery clamps.
VOLTAGE –
The digital display shows the voltage at
the charger battery clamps, in DC volts.
RATE SELECTION BUTTON
Use this button to select one of the following:
3A MAINTAIN –
For charging small batteries, such as
those commonly used in garden tractors,
snowmobiles and motorcycles. Also used
to maintain fully charged large batteries.
15A RAPID CHARGE –
For charging automotive, marine and light
truck batteries. Not intended for industrial
applications.
BATTERY TYPE BUTTON
Use this button to select the battery type.
STANDARD – Used in cars, trucks and
motorcycles, these batteries have vent caps
and are often marked "low maintenance" or

11. OPERATING INSTRUCTIONS

WARNING: A spark near the battery may
cause an explosion.
IMPORTANT: Do not start the vehicle with
the charger connected to the AC outlet, or
it could result in damage to the charger.
NOTE: This charger is equipped with
an auto-start feature. Current will not be
supplied to the battery clamps until a
battery is properly connected. The clamps
will not spark if touched together.
CHARGING A BATTERY
IN THE VEHICLE
1. Turn off all the vehicle's accessories.
2. Keep the hood open.
3. Clean the battery terminals.
4. Place the charger on a dry, non-
flammable surface.
5. Lay the AC/DC cables away from any
fan blades, belts, pulleys and other
moving parts.
6. Connect the battery, following the
precautions listed in sections 6 and 7.
7. Connect the charger to an electrical
outlet.
8. Select the battery type and charge rate.
"maintenance-free". This type of battery is
designed to deliver quick bursts of energy
(such as starting engines) and has a greater
plate count. The plates are thinner and have
somewhat different material composition.
Regular batteries should not be used for
deep-cycle applications.
AGM – The Absorbed Glass Mat
construction allows the electrolyte to be
suspended in close proximity with the
plate's active material. In theory, this
enhances both the discharge and recharge
efficiency. The AGM batteries are a variant
of Sealed VRLA (valve regulated lead-acid)
batteries. Popular uses include high-
performance engine starting, power sports,
deep-cycle, solar and storage batteries.
GEL CELL – The electrolyte in a GEL cell
has a silica additive that causes it to set up
or stiffen. The recharge voltages on this type
of cell are lower than those for other styles of
lead-acid battery. This is probably the most
sensitive cell in terms of adverse reactions
to overvoltage charging. Gel batteries are
best used in VERY DEEP cycle application
and may last a bit longer in hot weather
applications. If the wrong battery charger is
used on a gel cell battery, poor performance
and premature failure will result.
9. When charging is complete,
disconnect the charger from the AC
power, remove the clamps from the
vehicle's chassis, and then remove
the clamp from the battery terminal.
CHARGING A BATTERY
OUTSIDE OF THE VEHICLE
1. Place battery in a well-ventilated area.
2. Clean the battery terminals.
3. Connect the battery, following the
precautions listed in sections 6 and 7.
4. Connect the charger to the electrical
outlet.
5. Select the battery type and charge rate.
6. When charging is complete,
disconnect the charger from the AC
power, disconnect the negative clamp,
and finally the positive clamp.
7. A marine (boat) battery must be
removed and charged on shore.
CHARGE RATE
The charger will automatically adjust the
charging current, based on battery size,
in order to charge the battery completely,
efficiently and safely.
