Step 2
Line up the bracket’s two holes over the solar panel bracket’s holes and use the supplied Flush Head screws
to secure the bracket to the panel.
Step 3
Repeat these steps for the other three remaining brackets if required.
FREQUENTLY ASKED QUESTIONS
Q: Will the Battery Doctor’s
®
9 watt Model #23144 keep my vehicle battery maintained?
A: Great question! Model #23144 compensates for natural voltage losses and key-off small instrumentation
drain by replenishing and maintaining your battery up to a maximum rate of 750m Amps in full sunlight.
Q: What types of batteries can I maintain?
A: You can maintain all types of rechargeable 12V batteries including automotive batteries, deep cycle (trac-
tion) batteries, gel-cell batteries, and heavy-duty (stationary) batteries.
Q: Can the Battery Doctor’s
®
9 watt Model #23144 drain my battery at night?
A: No. Battery Doctor’s
®
9 watt Model #23144 solar panels are equipped with a built-in diode, which pre-
vents reverse current.
Q: Can I overcharge my battery with the Battery Doctor’s® 9 watt Model #23144?
A: The Battery Doctor’s
®
9 watt Model #23144 may overcharge a vehicle battery in certain situations.
We therefore recommend that you use a 10 Amp solar battery controller, sold separately, with Model
#23144.
Q: Can I start or drive my vehicle with the Battery Doctor’s
®
9 watt Model #23144 connected to the cigarette
lighter socket (12 volt lighter adapter) or battery?
A: No. For safety reasons please make sure the panel is not in use while you are using your vehicle.
Q: Can the Battery Doctor’s
®
9 watt Model #23144 be left outdoors?
A: Yes. This solar panel is weather resistant. However, if this solar panel is unreasonably weathered, the
warranty will become void.
Q: Will the Battery Doctor’s
®
9 watt Model #23144 always charge the battery through the cigarette lighter
socket (12 volt lighter adapter)?
A: Good question! In some vehicle models, the cigarette lighter socket (12 volt lighter adapter) is inactive
while the vehicle is off. Please consult your car owner’s manual. In the event that your car presents this
limitation, use the battery clamps provided with the unit in order to connect it directly to your battery.
Q: How do I know if the panel is working?
A: Use a voltmeter to measure the voltage of the panel. The voltage reading should be between 16 and 25
Volts in full sun.
Q: What does it mean if the LED does not light up on Voltage Indicator?
A: If the LED is not lit, it may mean that you are not exposing the unit to enough daylight. Please position the
solar panel to maximize its exposure to the sun. In rare instances the LED indicator may have burned out
yet the panel is still working effectively. You can test the solar panel’s output with a voltmeter.
Q: How long does it take to charge a lifeless battery?
A: If the battery seems lifeless, a larger output solar charger such as the 20 watt unit (Model #23145) is
needed. If the battery is truly dead, no charger will bring the battery back.
General Product Description
Battery Doctor’s
®
Model #23144 capture the energy of the sun to generate power that can charge a 12 Volt
battery for small power applications such as lighting systems or any small appliance.
The battery bank is an important component of any off-grid solar charging system, and we suggest using a
deep-cycle battery. A 12 Volt battery is not included in this kit and is sold separately.
Please note: A full battery has a voltage of 12.8 Volts. Never deeply discharge your battery; never let your bat-
tery voltage pass 11.0 volts. It will cause permanent damage to the battery. Use a DMM (Digital Multi-Meter)
to measure your battery’s voltage.

9 Watt Maintainer (Model #23144)
Specifications and included items:
Power Rating: Up to 9 Watts
Current: Up to 750m Amps @ 12 Volts
Includes: Alligator Clamps, 12 Volt DC Plug, 8’ 8” Wire, (4) Steel Mounting Brackets, Tilting Rods, Voltage Indica-
tor
Installation
Securely place the solar panel in the sun. Included mounting brackets and screws can be used if necessary for
permanent installation. Tilting rods are also supplied positioning the solar panel at an angle.
Installation through 12 Volt DC Plug:
Plug the included 12V DC Plug into the 12 Volt DC socket (cigarette lighter socket) in vehicle. Make sure both
ends are secure and aligned correctly. For optimal power, ensure the panel (solar cell up) is directly facing the
sun.
Installation using Battery with Alligator Clamps:
Connect the included alligator clamps correctly by matching up the red clamp which is Positive (+) to the Posi-
tive (+) terminal on your battery. Connect the black Clamp which is Negative (-) to the Negative (-) Terminal
on your battery.
WARNING: Follow this carefully to avoid bodily harm; wrong connections may cause sparking or explo-
sion.
For optimal power, ensure the panel (with the solar cell facing up) is directly facing the sun.
NOTE:
This solar panel has a built in blocking diode to prevent “reverse discharge”. Please do not use this panel while
vehicle is in use. When operating your vehicle, it is best to secure the solar panel in another secure location. The
9W Solar Panel is weather resistant and can safely operate in most weather conditions.
BRACKET INSTALLATION
To install the mounting brackets, please follow the below instructions.
Step 1
Remove the screws from the silver bracket on the back side of the solar panel as shown in the picture. This
will require a small Phillips head screwdriver. The screws that are removed will not be needed to fasten the
bracket.
