IMPORTANT SAFETY
INSTRUCTIONS
CALIFORNIA PROPOSITION 65
WARNING: This product contains chemical known to the state
of California to cause cancer or reproductive toxicity.
1.
SAVE THESE INSTRUCTIONS
– This manual contains important safety and operating
instructions for battery charger Models D250S DUAL
(1044) and SMARTPASS (1058).
2. Use of an attachement not recommended or sold by the
CTEK may result in a risk of fire, electric shock, or injury to
persons.
3. When charging, batteries can emit explosive gases,
therefore it is essential to prevent flames and sparks. The
charger is designed for charging 12V lead-acid batteries.
Do not use for any other purpose.
4. Always provide good ventilation when charging.
5. Make sure that cables used have sufficient cable area,
see CABLE DIMENSIONS.
6. Do not operate charger with damaged cord - replace the
cord immediately.
7. Never operate the charger if it has received a sharp blow,
been dropped or otherwise damaged in any way; take it
to a CTEK representative.
8. Do not disassemble charger; take it to the retailer when
service or repair is required. Incorrect reassembly may
result in a risk of electrical shock or fire.
9. Disconnect the products before attempting any maintenance or cleaning

GENERATE EXPLOSIVE GASES
DURING NORMAL BATTERY
OPERATION. FOR THIS
REASON, IT IS OF UTMOST
IMPORTANCE THAT, YOU
FOLLOW THE INSTRUCTIONS
EACH TIME YOU INSTALL THE
CHARGER.
b) To reduce risk of battery explosion, follow these instruc-
tions and those published by the battery manufacturer
and the manufacturer of any equipment you intend to use
in vicinity of battery. Review cautionary marking on these
products and on engine.
c) Disconnect battery poles before installation
d) D250S DUAL is not reverse polarity protected.
11.
PERSONAL PRECAUTIONS
a) Consider having someone close enough by to come to
your aid when you work near a lead-acid battery.
b) Have plenty of fresh water and soap nearby in case bat-
tery acid contacts skin, clothing or eyes.
4 • EN
c) Wear complete eye protection and clothing protection.
Avoid touching eyes while working near battery.
d) If battery acid contacts skin or clothing, wash immediately
with soap and water. If acid enters eye, immediately flood
eye with running cold water for at least 10 minutes and
get medical attention immediately.
e) NEVER smoke or allow a spark or flame in vicinity of bat-
tery or engine.
f) Be extra cautious to reduce risk of dropping a metal tool
onto battery. It might spark or short-circuit battery or other
electrical part that may cause explosion.
g) Remove personal metal items such as rings, bracelets,
necklaces, and watches when working with lead-acid
battery. A lead-acid battery can produce a short-circuit
current high enough to weld a ring or the like to metal,
causing a severe burn.
h) Use charger for charging a LEAD-ACID battery only. Do
not use battery charger for charging dry-cell batteries that
are commonly used with home appliances. These batteries may burst and cause injury to persons and damage to
property.
i) Never charge a frozen battery.
12. PREPARING TO CHARGE
a) If necessary to remove battery from vehicle to charge,
always remove grounded terminal from battery first. Make
sure all accessories in the vehicle are off, so as not to
cause an arc.
b) Be sure area around battery is well ventilated while bat-
tery is being charged.
c) Clean battery terminals. Be careful to keep corrosion from
coming in contact with eyes.
d) Add distilled water in each cell until battery acid reaches
level specified by battery manufacturer. Do not overfill.
For a battery without removable cell caps, such as valve
regulated lead acid batteries, carefully follow manufacturer’s recharging instruction.
e) Study all battery manufacturer’s specific precautions while
charging and recommended rates of charge.
f) Determine voltage of battery by referring to vehicles
manual.
13.
CHARGER LOCATION
a) Never place charger directly above battery being
charged; gases from battery will corrode and damage
charger.
b) Never allow battery acid to drip on charger when read-
ing electrolyte specific gravity or filling battery.
c) Do not set a battery on top of charger.
14. FOLLOW THESE STEPS WHEN
BATTERY IS INSTALLED IN
VEHICLE. A SPARK NEAR
BATTERY MAY CAUSE BATTERY
EXPLOSION. TO REDUCE RISK
OF A SPARK NEAR BATTERY:
a) Position cords to reduce risk of damage by hood, door or
moving engine part.
b) Stay clear of fan blades, belts, pulleys, and other parts
that can cause injury to persons.
c) Check polarity of battery posts. POSITIVE (POS, P, +)
battery post usually has larger diameter than NEGATIVE
(NEG, N, -) post.
d) Determine which post of battery is grounded (connected)
to the chassis. If negative post is grounded to the chassis
(as in most vehicles) see (e). The battery charger can
not be used with positive-grounded batteries.
e) For Negative-grounded vehicle, connect POSITIVE con-
nector from battery charger to POSITIVE (POS, P, +)
ungrounded post of battery. Connect NEGATIVE connector from battery charger to vehicle chassis or engine block
away from battery. Do not connect to carburetor, fuel
lines, or sheet-metal body parts. Connect to a heavy gage
metal part of the frame or engine block.
f) When disconnecting charger, always do so in reverse
sequence of connecting procedure and break first connection while as far away from battery as practical.

15. FOLLOW THESE STEPS WHEN
BATTERY IS OUTSIDE VEHICLE.
A SPARK NEAR BATTERY MAY
CAUSE BATTERY EXPLOSION.
TO REDUCE RISK OF
A SPARK NEAR BAT TERY:
a) Check polarity of battery terminals. POSITIVE (POS,
P, +) battery post usually has a larger diameter than
NEGATIVE (NEG, N, -) post.
b) Attach at least a 24-inch-long 6-gauge (AWG) insulated
battery cable to NEGATIVE (NEG, N, —) battery post.
c) Connect POSITIVE charger connector to POSITIVE (POS,
P, +) post of battery.
d) Position yourself and free end of cable as far away from
battery as possible – then connect NEGATIVE charger
connector to NEGATIVE (NEG, N, -) post of battery.
e) Do not face battery when making the final connection.
f) When disconnecting charger, always do so in reverse
sequence of connecting procedure and break first connec-
tion while as far away from battery as practical.

wiring system; or an equipment-grounded conductor should
be run with circuit conductors and connected to equipmentgrounded terminal or lead on battery charger. Connections
to battery charger should comply with all local codes and
ordinances.
D250S DUAL
The D250S Dual has 2 inputs. The Service battery will be
charged from the alternator, solar panel, or both in combination. The solar panel adjusts itself to the Starter battery voltage.
The Starter battery will be charged and maintained directly by
the solar panel if the Service battery is fully charged.
D250S DUAL
FEATURES:
•Multi-step 20A temperature compensated battery charging
and battery maintenance.
•Battery separation of Starter and Service batteries.
•Maximum power point tracking for solar panels charging
the Service battery.
•Two power source inputs (alternator, solar, wind, Supply
battery and other).
•Coordination of the two inputs, allowing parallel operation.
•The solar input will also maintain the Alternator battery.
•Built in battery guard for the Alternator battery.

SMARTPASS
SMARTPASS can operate as a stand-alone unit, but works best
in combination with D250S Dual. The SMARTPASS creates
a priority path for charging the Service battery to recharge
it more quickly and efficiently. Attached energy sources like
solar, wind or shore power will charge both the Service and
the Starter batteries through the SMARTPASS. Service batteries
that are overheated due to age, high ambient temperature or
other battery problems will be protected from high alternator
current.
SMARTPASS
FEATURES:
The CTEK SMARTPASS adds additional functionality for higher
output alternators, larger battery banks and/or high parallel
loads.
•Separation of consumers and Service batteries during
charging, which improves the charging capacity significantly, and lowers the consumer voltage, which increases
expected service life of lights and other electronics.
•Service battery watch, which avoids harmful deep discharges that otherwise would shorten battery life. The battery watch also protects navigation, radio and emergency
light from being out of electricity.
•Over-temperature protection of Service battery. High battery temperature could significantly reduce battery life.
•Maintenance charge of Starter battery, which simplifies
installation with fewer components.
•Simplified installation of AC/DC chargers (shore power).
Only one output from the AC/DC charger needed.
The CTEK SMARTPASS is designed to work together with
1-2 CTEK D250S DUAL, but can also be used alone.
