Note: It is the color and internal design of the cap that determines the charge profile, not the
alignment of the debossed letters for the battery type on the cap.
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:
11 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 ProSport On-Board Marine
Battery Charger. Open all battery and engine compartments and ventilate for at least
15 minutes before starting the installation of the ProSport Charger.

. Prepare each battery in advance by cleaning each terminal post with a wire
brush until a shiny surface is obtained.
IMPORTANT NOTICE
As you prepare to attach the positive (red) and negative (yellow) charger output
leads to the batteries there will be brief low power spark that is generated as
you make the connection. This is due to the high frequency capacitors taking
a charge. Make sure the (yellow) 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, as illustrated on pages 10 and 11.

. Confirm the selected mounting location allows for a minimum of 8 inches of free space
around front and sides of the ProSport charger. Do not install charger on carpeted ,
upholstered, vinyl, or varnished areas. Be sure to place the ProSport in an accessible area
where all indicators are viewable. 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.

. Using the ProSport as a template, mark the position of each mounting hole.
4
. Using a 1/8" drill bit, drill pilot holes in the (4) marked locations as described in step 3.
Apply a silicon sealer in each of the mounting locations to waterproof the screw holes.
5
. Position the ProSport over the mounting holes and secure with a power screwdriver
by installing 4 stainless steel screws.

IMPORTANT NOTICE
Confirm the surface you will be
mounting the charger to is
adequate in strength and
thickness to hold the ProSport
in place with the mounting
screws you have selected.

Selecting a Charging Profile & Understanding Battery Types
Understanding Battery Types
There are three primary types of batteries in the marketplace today; Flooded (Lead-
acid), AGM (Absorbed Glass Mat) and GEL cell (Gelled Electrolyte Lead-acid). Traditionally,
the most common type of batteries used are 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.
***If you are still unsure what kind of battery(s) you have, we recommend that you
contact the manufacturer of the battery(s).
NOTE: AGM (Absorbed Glass Mat) batteries are not GEL (Gelled Electrolyte Lead-acid) batteries and
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.
Battery Type
Charging Profile
Flooded (Lead-acid) - with or without fill caps
AGM (Absorbed Glass Mat) - Sealed
GEL Cell - Sealed
14.6 VDC Absorption, 13.4 VDC Float
14.1 VDC Absorption, 13.8 VDC Float
Your Battery Charger is equipped with a user programmable
battery type selector that is factory set for Flooded (Lead-
acid) / AGM (Absorbed Glass Mat) batteries.
To program your ProSport On-Board Marine Battery Charger for
GEL (Gelled Electrolyte Lead-acid) batteries simply remove the
black programming cap
and replace it with the
gray programming
cap that is marked GEL
. Any time you re-program or change the
cap, apply marine silicone to the threads of the cap being installed.
