General Overview

The ProSport Charger is an advanced electronic and fully automatic multi-stage on-board marine battery charger. ProSport is pre-wired for easy installation and is 100% waterproof for fresh and saltwater applications. ProSport’s multi-stage charging process delivers five modes of operation that include: start-up diagnostics, charging, conditioning, auto maintenance, and storage reconditioning of each battery. This process is proven to extend the life of your batteries and will fully charge your batteries each time you connect to AC power. ProSport delivers increased power and performance while providing improved durability and heat transfer.

The ProSport Distributed-On-Demand™ Charging Technology will automatically sense and distribute 100% of the available charging output of 8,12, 15, or 20 amps (model specific) to any one battery or combination of all batteries. Each battery charger output is fully isolated. ProSport’s easy-to-view LED indicators will provide at-a-glance status of: AC power, battery type, charging, and ready status. The LED status center also includes an indication of a fault or failure detected at each battery that is connected to the charger and can be seen on the top of the unit when installed.

Note: ProSport On-Board Marine Battery Chargers are designed for any combination of group 24,27,30 and 31 batteries. Each battery charger DC output cable must be connected to one (1) 12 Volt DC battery (even if batteries are configured for 24 Volt DC or 36 Volt DC trolling motor or system applications).

Important: The pair of red and black wires in 1 cable jacket MUST GO TO THE SAME 12VDC battery.How Distributed-On-Demand™ Charging Technology Works

ProSport’s Distributed-On-Demand™ Charging Technology ensures that 100% of the available charging amps are fully utilized to meet the demand of each battery on-board. For example, if your engine start battery only needs 2 amps from your ProSport 12 (6/6 two bank charger) the unused 4 amps will be automatically Distributed-On-Demand™ to your house or trolling motor battery, providing a total of 10 amps for faster charging versus only 5 amps that the conventional 5/5 battery charger would provide. The competitive 5/5 charger has a 5 amp limit per bank.

General Operation

Install your ProSport On-Board Marine Battery Charger according to the guidelines in this manual. Make sure your charger and batteries are properly vented. Connect your extension cord with no AC power present to the ProSport and proceed to plug your extension cord in at a nearby 120/230 VAC GFCI-protected (Ground Fault Circuit Interrupt) outlet. With your ProSport plugged in properly, it will automatically/fully charge your batteries while it conditions and extends the life of your batteries. Always leave your charger plugged in to reduce sulfate build-up allowing your batteries to be fully charged and maintained for your next fishing trip.

The ProSport design incorporates a new storage recondition mode that stimulates and reconditions your onboard batteries for 3 hours once a month and when completed will resume its normal auto maintain mode. During the storage recondition mode the ready/maintain LED will remain green and the storage recondition mode LED will fade-in fade-out pulse, indicating your batteries are being reconditioned and are fully charged during this process.

ProSport LED Status Center – Operation and Display

ProSport includes 7 LEDs for operation status and up to 3 battery bank trouble LEDs depending on the model.

1. The blue AC power LED
   Illuminates when AC power is applied
2. The battery-type LED
   Will illuminate red for standard Flooded (lead-acid)/AGM and green for GEL.
   Note: The ProSport 20 Dual bank model includes an amber battery type LED for AGM HP (High Performance) battery type. Please read the battery manufacturer literature carefully and select the correct charge profile. Failure to do so may cause early battery failure.
3. The system checks OK LED
   After applying AC power the ProSport will self-test and analyze all battery connections
   and batteries. If all checks are OK the green LED will illuminate. This can take up to 2 minutes.
4. The charge mode LEDs
   • Charging: Red LED will flash during the self-test and battery test mode (approximately 1-2 minutes) and will be solid red during charging.
   • Conditioning: Amber LED illuminates during conditioning mode.
   • Auto Maintain: Green LED illuminates when batteries are fully charged and are automatically maintained until you are ready to use your boat.
   • Storage Recondition: Green LED fades in and out when performing a once-a-month storage recondition mode.
5. Battery bank trouble status LEDs
   Red LEDs will illuminate indicating a wiring problem or fault at one of the batteries connected
   to the ProSport charger. See page 25 for further details.

Operation after Applying AC Power to a ProSport Charger Connected to Discharged Batteries

(The following example is for the factory setting of Flooded (lead-acid) batteries) When power is applied the ProSport performs a self-test of the battery charger electronics and the batteries connected to the battery charger. During the startup test, the battery type LED will be illuminated and the red charge mode LED will flash indicating that the unit is in a self-test mode. When complete and if there are no faults, the charger’s system checks OK indicator will illuminate green and the ProSport’s solid red charging LED will be ON indicating the charging process is initiated.

Note: If there is a fault the appropriate bank LED will illuminate and the charge process may not start, depending on the location of the fault. See page 25 for further troubleshooting details.

If there are no Battery Faults, the Green System Check OK LED will illuminate and the following sequences will proceed:

• The red battery-type LED (factory set for standard Flooded (lead-acid)/AGM batteries) will illuminate.
• The red charge mode LED will illuminate indicating the charger has started its multi-stage charging process.
• When the charging process is approximately 80% complete the red charge mode indicator will turn off and the amber conditioning LED will turn on indicating the conditioning mode.
• When the multi-stage charge process is completed you will observe the following: Battery type red LED goes OFF.
• The red charging LED and the amber conditioning LED will be off and the green ready/maintain LED will illuminate indicating your batteries are fully charged.
• The only LEDs on after the multi-stage charge process is completed are the green system OK LED, the blue AC power LED, and the green ready/maintain LED.

Multi-Stage Charging Overview

• Stage 1 – System Check OK and Battery Analyzing: During this stage, the ProSport red “Charge” LED will flash indicating ProSport is analyzing all battery connections in addition to checking each battery is capable of being charged. Upon completion, the “System Check OK” indicator will illuminate green followed by Stage 2 Charging.
• Stage 2 – Charging: During this mode, the “Charging” indicator will be red. The ProSport Series will use all of its available charging amps (as controlled by temperature) until the battery voltage is raised to 14.6 VDC (Flooded lead-acid factory setting).
• Stage 3 – Conditioning: During this mode the “Conditioning” status indicator will be amber. Batteries will hold at 14.6 VDC (factory set for Flooded lead-acid batteries) to complete charging while conditioning each battery connected. Upon completion, the ProSport will go into its Energy Saver Mode.
• Stage 4 – Auto Maintain (Energy Saver Mode): During this mode, the blue “Power” and green “Auto Maintain” LEDs will be on indicating Stage 2 charging and Stage 3 conditioning are completed. At this time ProSport will initiate its Auto Maintain (Energy Saver Mode) which will monitor and Auto Maintain batteries only when needed to maintain a full state of charge.
• Stage 5 – Storage Recondition Mode: During this mode the ProSport “Storage Recondition Mode” green indicator will illuminate with a slow fade in and out pulse. This indicates that while your batteries/boat are in storage the ProSport will automatically recondition all batteries for up to 3 hours once a month extending battery life and maximizing the water battery power performance.

Selecting a Charging Profile & Understanding Battery Types

Your battery charger is equipped with a user-programmable battery type selector that is factory-set for standard Flooded (lead-acid) / AGM (Absorbed Glass Mat) batteries. To set your charger for Gel batteries simply remove the black programming cap and replace it with the Gel programming gray cap. If you own a ProSport 20 Dual Bank Charger you also have the option to use the High Performance AGM profile recommended for OPTIMA BlueTop Deep Cycle and Odyssey AGM marine batteries by installing the blue AGM HP programming cap. Any time you reprogram or change the cap, apply marine silicone to the threads of the cap being installed.

NOTE: AGM (Absorbed Glass Mat) batteries are not Gel (Gelled Electrolyte Lead-acid) batteries. Gel batteries require a completely different charge profile that must be selected versus the out-of-the-box factory setting.AGM batteries can accept the same charging profile as Flooded (lead-acid) batteries.
Understanding Battery Types & Charger Settings. There are three primary types of batteries in the marketplace today; standard Flooded (lead-acid), AGM (Absorbed Glass Mat), high-performance AGM and Gel cell (Gelled Electrolyte Lead-acid). Traditionally, the most common type of batteries used is Flooded (lead-acid) batteries. Almost all Gel cell batteries will state that they are Gel cell on the battery case or labels. Shown below are typical battery voltages at absorption and float levels.

Installation

• All ProSport Battery Chargers are designed to be permanently mounted on-board and should be mounted with extruded fins placed horizontally.
• Always mount your ProSport in a compartment area that can be properly ventilated during use.
• Do NOT mix battery types on board. All batteries should be of the same age and in good operating condition.
• Do NOT make any electrical connections to the ProSport or batteries until the following steps are completed:

10 Easy to follow installation steps:

1. Select a mounting location that allows for free air ventilation with a minimum of 8 inches of clear unobstructed space around and in front of the battery charger. Open all battery and engine compartments and ventilate for at least 15 minutes before starting the installation of the charger. Confirm all battery cables can reach each of the batteries.
   • Note: For installations requiring an extension of the DC battery charger cables, please call or visit your retailer or dealer to purchase ProMariner’s 5-foot or 15-foot battery charger DC cable extenders. Our innovative cable extenders are properly fused and do not require any cutting or stripping of wires. If you have any problems locating this accessory call ProMariner at +1-800-824-0524.
2. Using the ProSport charger as a template or the enclosed paper template, mark the position of each
   mounting hole. Ensure the mounting screws will not puncture or protrude into a live well, a fuel or oil tank, or the bottom of the boat.
3. Using a 1/8” drill bit, drill pilot holes in the (4) marked locations as described in step 2. Apply a silicon sealer in each of the mounting locations to waterproof the screw holes.
4. Position the charger over the mounting holes and secure it with a power screwdriver by installing 4 stainless steel # 10 screws. (mounting screws not included).
5. Prepare each battery in advance by cleaning each terminal post with a wire brush until a shiny surface is obtained.
6. Run cables free from sharp objects and hold each in place with cable ties. Coil excess cable, do not cut or shorten the length of the cables, as in-line fuses are located 4 inches from the end of each positive (red) cable. In addition, there are fuses in all but one of the negative (black) leads. These fuses protect the charger and output cables in the event of a wiring short. We recommend the use of wire ties or cable clamps to provide strain relief for the cables and to reduce the risk of damage to the cables or connections.
7. Connect the DC output cables as illustrated on pages 16-22. Make sure the (black) wires are connected as illustrated to the negative side of the battery and the (red) wires are connected to the positive side of the battery.
8. Make sure all DC connections are correct, tight, and free from corrosion.
9. Locate the AC power cord in an open-air area of your boat at least 21 inches from the charger, batteries, and fuel fill lines.
10. Connect a heavy-duty UL-approved extension cord to the battery charger first. After connecting the
    extension cord to the charger, proceed to plug the extension cord to a nearby 120/230 VAC
    GFCI-protected (Ground Fault Circuit Interrupt) outlet. Always remove the extension cord from the 120/230 VAC outlet first when charging is completed, followed by unplugging the charger. You are now connected and charging your batteries. View the LED indicators.

4 Steps to Wire your ProSport Charger Correctly

• STEP 1: Simply choose the illustration that has the same number of charger output bank cables as your ProSport Battery Charger in hand and wire exactly as shown (choose the illustration that matches your application) for proper charger operation.
• STEP 2: Do not remove your batteries series or parallel jumper cables that interconnect batteries to each other. ProSport Chargers are designed with isolated outputs and series or parallel jumper cables do not have to be removed.
• STEP 3: Your ProSport charger will not operate properly if it is not connected properly to each battery. Reminder, the ProSport and each DC jacketed bank cable must be properly connected to “individual 12V batteries”. Number of DC jacketed bank cables equals the number of batteries that must be individually connected. Example: a three bank ProSport 20 3 Bank must be connected to 3 individual 12V batteries. As Illustrated on Pages 16-22. Select your battery / trolling motor configuration for the specific wiring illustration needed for your charger.
• STEP 4: Incorrect wiring will result in reverse polarity or high reverse voltage, in the event this happens, the ProSport Charger has been designed to not fail as a result, however it will cause the charger to “internally disconnect” and provide “no output” until the (reverse polarity caused by putting the “red” + lead on a – negative battery terminal) and or the (high reverse DC voltage caused by taking one bank cable and spreading it across two batteries) is corrected, using the wiring diagrams as shown on pages 16-22. In the event of a reverse polarity connection or an improper battery connection or if an output is not connected to a battery the appropriate red battery bank trouble LED will illuminate identifying the battery and wiring connections where a fault is present. See page 25 for further details.

Installation

When connecting each jacketed battery charger cable, make sure it is connected to only one 12 VDC battery and observe the polarity and color of all connections:

• Red Wire = + (Positive) Battery connection
• Black Wire = – (Negative) Battery connection

The black wire can never be connected to a terminal with red wires. Only black.
Important: The pair of red and black wires in 1 cable jacket MUST GO TO THE SAME 12VDC battery.
