INTRODUCTION
Pro Charging Systems (PCS) has been manufacturing waterproof, on-board battery charging
systems for the marine industry since 1989. Our charging systems are designed and built tough
to withstand intense vibration, extreme temperature variations and submersion without damaging
the unit. Our systems use temperature compensation in order to fully charge a battery in hot or
cold environments and are controlled by microprocessors in order to assure precise control over
each totally independent charging bank. All of our chargers have true reverse polarity protection
and incorporate a float maintenance mode upon completion of each charge cycle.
IMPORTANT SAFETY INSTRUCTIONS
Use of attachments not recommended or sold by PCS may result in a risk of fire, electrical shock,
or injury to persons.
To reduce risk of damage to the electrical plug and power cord, always pull by the electrical plug
rather than by the power cord when disconnecting charger.
When using an extension cord, make sure:
1. That pins on the extension cord plug are the same number, size and shape as those of
the charger’s plug;
2. That extension cord meets UL (Underwriters Laboratories, Inc.) acceptance and is in
proper operating condition;
3. That wire size is large enough for the ac ampere rating of charger.

Do not operate charger with a damaged cord or plug. Replace the cord or plug immediately.
Do not operate charger if it has received a sharp blow, or if it has been dropped or otherwise
damaged in any way; contact our technical support group for assistance (800.742.2740).
Do not disassemble charger; contact technical support when service or repair is required.
Incorrect reassembly may result in risk of electrical shock or fire.
To reduce risk of electrical shock, unplug charger from outlet before attempting any maintenance
or cleaning.
WARNING: RISK OF EXPLOSIVE GASES
1. WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. Batteries
generate explosive gases during normal battery operation. For this reason, it is of utmost
importance that prior to each use of your charger, you read this manual and follow the
instructions exactly.
2. To reduce risk of battery explosion, follow these instructions and those published by the
battery manufacturer and by the manufacturer of any equipment you intend to use in the
vicinity of battery. Review all cautionary markings on any product being utilized in or
around the charging device.
PERSONAL PRECAUTIONS
Someone should be within range of your voice or close enough to come to your aid when you
work near a lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, eyes, or
other surfaces.
Wear complete eye protection and clothing protection. Avoid touching eyes while working near
battery.
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 seek medical attention
promptly.
NEVER smoke or allow a spark or flame in the vicinity of a battery or engine.
Be extra cautious to reduce risk of dropping a metal tool onto battery. This might cause a spark
or short-circuit a battery, possibly resulting in an explosion.
Remove personal metal items such as rings, bracelets, necklaces, and watches when working
with a 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.
Use charger for charging a LEAD-ACID (lead acid, sealed lead acid, gel cell, and AGM) battery
only. It is not intended to supply power to a low voltage electrical system other than in a starter-
motor application. Do not use battery charger for charging dry-cell batteries that are commonly
used with home appliances. These dry cell batteries may explode, causing personal injury and
damage to property.
CAUTION: DO NOT ATTEMPT TO INSTALL THE XTREME IN A BATTERY CONFIGURATION
THAT UTILIZES A SERIES CONNECTION FROM THE CRANKING BATTERY TO ONE OF THE
TROLLING MOTOR BATTERIES. SEVERE SPARKING AND/OR DAMAGE TO THE PROXTRA
CIRCUITRY MAY OCCUR AND THE WARRANTY WILL BE VOIDED.

PREPARING TO CHARGE
If it is necessary to remove the battery or batteries to charge, always remove grounded terminal
from battery first. Make sure all accessories are off, so as not to cause battery arcing.
Be sure the area around any battery is well ventilated while batteries are being charged. “Gas
fumes” may be present during charging and can be forcefully blown away by using a piece of
cardboard or other nonmetallic material as a fan. Proper ventilation is always recommended in
the charging area.
Clean all of the battery terminals. Be careful to keep corrosion from coming into contact with
eyes.
Add distilled water in each cell (wet cell batteries) until battery acid reaches level specified by
battery manufacturer. This helps purge excessive gas from cells. Do not overfill. For a battery
without cell caps, carefully follow manufacturer’s recharging instructions.
Study all battery manufacturers’ specific precautions such as removing or not removing cell caps
while charging and recommended rates of charge.
Extension cords should be industrial grade/heavy duty UL approved and grounded. Check
extension cord before use for damage, bent prongs and cuts. Replace if damaged.
Always make your extension cord connection on the charger side first. After connecting the
extension cord to the charger, proceed to plug the extension cord into a 120 VAC GFCI protected
(Ground Fault Circuit Interrupt) outlet.
Always remove the extension cord from the 120 VAC outlet first when charging is completed
followed by unplugging the charger.
PRODUCT SUMMARY
General Operation:
Use the following guidelines in this manual to install your fully automatic PCS battery charging
system.
Assure that the area around your charger and batteries is properly ventilated. Connect your
extension cord with no A/C power present to the battery charger and proceed to plug your
extension cord in at a nearby 120 VAC GFCI protected (Ground Fault Circuit Interrupt) outlet.
Once you plug in your PCS battery charging system, your batteries will be simultaneously and
independently charged to 100%. Unlike systems that utilize one large charger to attempt to
charge multiple batteries, your system utilizes a totally independent battery charger for each
battery. Each charging bank will remain in a float stage once the battery is charged and then
monitor and/or maintain the battery indefinitely.
We recommend that you leave your system plugged in to reduce sulfation on the lead plates of
the batteries and to allow your PCS charging system to keep your batteries fully maintained and
ready to perform at their best. Your Xtreme Series system also utilizes specially designed
circuitry to enable independent charging current to flow to additional batteries. This system is
enabled and operates automatically whenever the engine starting battery is being charged and
maintained by the engine driven charging system.
Independent Charging Bank Indications
When your battery charging system is activated, each bank provides charging information utilizing
five red Light Emitting Diode (LED) indicators and one green Light Emitting Diode (LED) indicator.
These indications occur only when the charger is being powered by AC.

5
The five red LEDs enable you to track the progress of the charge cycle on each battery as the
voltage rises. Indications are as follows:
“Charging on the run” Indications
During periods in which the engine starting battery is being charged and maintained by the
engine driven charging system, amber and red LED indicators are provided that display the state
of the integrated ProXtra circuitry, which controls the flow of the current to additional batteries.
Indications are as follows:
CHARGING CRANKING BATTERY: This amber LED is illuminated whenever the voltage of the
engine starting battery is in excess of 13.0 Volts.
CHARGING ADDITIONAL BATTERIES: This red LED is illuminated during periods when the
Proxtra circuitry is allowing charging current to flow to additional batteries.
INSTALLATION INSTRUCTIONS
All PCS battery charging systems are designed to be permanently installed in a well-ventilated
area and have no mounting restrictions.
Do not make any electrical connections to the power supply (AC) or to a battery (DC) until the
installation process has been completed.
If mounting the charger in a boat, please choose a flat surface as high above the water level as
possible. If a compartment wall is chosen, make certain its strength is adequate to support the
weight of the charger.
Use the mounting flanges of the charger to mark locations for starter holes. Drill a 1/16 inch hole
at each marked location. Then, utilize all the stainless steel screws that have been provided and
install the charger securely, being cautious not to over tighten the screws. Silicon sealer should
be used to secure and waterproof the screw holes.

Before making any connections, prepare batteries as follows:
(a) With caps securely in place, thoroughly clean the case and posts with a solution of
baking soda and water. Be careful not to allow any baking soda to get inside the case.
(b) All battery posts, terminals and connectors should be cleaned to a shiny bright finish,
using a wire brush or sand paper. This should be done periodically to assure maximum
conductivity between the battery and the charger.
Charge Cables #1 and #2
Each charge cable assembly is equipped with a temperature sensor located at the junction of
each set of ring terminals. Attempts to shorten the cables could partially disable the charger.
Therefore, we recommend that you do not make any adjustments without first consulting our
technical support group (800.742.2740).
Route your charge cables from the charger to your batteries, being cautious to avoid sharp
objects, and use the supplied wire ties to hold them securely and neatly in place. Securely
connect the red (+) charger ring terminals to the positive battery posts and the black (-) charger
ring terminals to the negative posts. If the unit is equipped with a standard AC plug on the power
cord, a plug receptacle is also provided to hold the power cord plug when it is not being used.
Locate a convenient site for the receptacle and attach it using the four smaller stainless steel
screws.
Cranking Battery Cable
The cable assembly designated for the engine starting battery is unique in that in addition to the
Red (+) and Black (-) wires, there is a purple wire that must be attached to a 12 Volt source,
which is switched on and off by the engine ignition key switch. Use the supplied quick connector
to attach the purple wire to any key activated 12 Volt source. It is important to note that the
“charge on the run” circuitry will not operate unless the purple wire is connected to a 12 Volt
source.
TROUBLE SHOOTING
PROBLEM: No LED indicators illuminate in any of the charger banks.
Solution Sequence: Check the AC power supply from its source through all connecting points up
to the charger by using a meter or test light to confirm that current is being delivered to the
charger.
PROBLEM: One red LED flashing

7
Solution Sequence: With the AC power supply cord unplugged, check the ring terminals for
correct polarity (Red to positive or + and Black to negative or -). Also check for corrosion free
secure connections to the batteries. Call technical support for further assistance (800.742.2740).
PROBLEM: The LED indications change rapidly back and forth from red to green, or the
green LED will not illuminate after excessive charging time (16 hours or more).
Solution Sequence: Disconnect AC power to the charging system. On multi bank chargers,
remove the charge cable assembly of the affected bank from the battery. Take the original
charge cable assembly from this battery and attach it to the battery from which you removed the
first cable. Plug the charger in and observe the LED indications. If the rapid LED sequence (red
to green repeatedly) occurs on a different bank of the charger, this confirms that a battery
problem exists.
PROBLEM: The green (READY) LED was illuminated before disconnecting the power from
the charger, but upon reconnection, the red (CHARGING) LED appears and remains on.
Solution Sequence: This is normal operating procedure for the system and simply indicates that
a re-analysis of the battery status has been initiated and after a series of steps, the green LED
will illuminate.
PROBLEM: The indicator lights from the ProXtra II “charge on the run” system are not
illuminating while the main boat engine is running.
Solution Sequence:
Check that each charge cable ring terminal is attached securely and with proper polarity.
Check that the purple 12 Volt sense wire from the cranking battery cable assembly is installed
properly.
Check engine RPMs. The system may not operate with the engine at idle. Assure that the
system has been tested at higher engine RPMs.
For further troubleshooting, please contact technical support (800.742.2740).
PROBLEM: One or both indicator lights on the ProXtra II “charge on the run” system
remain on after the main engine is shut down.
Solution Sequence: It is normal for the “charging additional batteries” and “charging cranking
battery” lights to remain on for a brief period of time following main engine shutdown. As the
battery voltages decrease, the lights will extinguish.
If one or both lights remain on indefinitely, please contact technical support (800.742.2740).
POST-INSTALLATION TESTING
After completing the total installation process for your Xtreme system, it is possible to test the
ProXtra II section of the system for proper operation without having to operate the main engine.
Attach a battery charger designed for a 12 Volt system to the cranking battery.
Turn the ignition key switch to the ON position.
Turn the charger on and observe the indicator lights on the ProXtra II section of the Xtreme.
When the voltage of the cranking battery reaches a predetermined level, the “charging cranking

8
battery” light will illuminate. As the voltage of the cranking battery continues to rise, the “charging
additional batteries” light will illuminate.
Once both indicator lights have illuminated, unplug the charger attached to the cranking battery.
As the battery voltage drops to a predetermined level, both indicator lights should extinguish.
If unable to accomplish the previous steps for any reason, please call PCS technical support
(800.742.2740) for further assistance.
