Sequential Multi-Stage Charging Overview
Upon applying AC power to your ProSport On-Board Marine Battery Charger, the
following will be observed (all LEDs will flash as a self test):
The Blue AC Power LED will illuminate followed by the Red Charging LED and Red Battery Type LED
(Factory setting for standard Flooded (Lead-acid)/AGM batteries). The combination of these three
LED’s turning on indicates ProSport has started its Sequential Multi-Stage Charging process. When
the Charge Process is completed, only the Green READY and Blue AC Power LEDs will be illuminated.
ProSport’s Sequential Multi-Stage Charging process delivers three sequenced modes of
operation that include: Charging, Conditioning and Maintenance of each battery. This process
is proven to extend the life of your batteries and will fully charge your batteries each time.
Stage 1: ProSport Charging
During this mode, the ProSport will use its available charging amps (as controlled
by temperature) until battery voltage is raised to 14.6 VDC (Factory setting for
standard Flooded (Lead-acid) / AGM batteries).
Stage 2: ProSport Conditioning
The ProSport will hold batteries at 14.6 VDC (Factory setting for Flooded (Lead-acid) / AGM
batteries) providing a 100% charge to each battery, while conditioning batteries by desulfating
each battery. Upon completion, the ProSport will go to into its maintenance mode.
Stage 3: ProSport Ready / Maintenance Mode
During this mode, the Red Charging LED and the RED Battery Type LED (Factory set
charge profile for standard Flooded (Lead-acid / AGM Batteries) will turn off indicating
the Charge Process is completed, followed by the Green READY LED turning On.
The Green READY LED and the Blue AC POWER LED will remain on indicating that your
batteries are fully charged and are being maintained with a precision 13.4 Volts DC
Finishing Voltage (Factory set charge profile for standard Flooded (Lead-acid / AGM
Batteries). ProSport’s Ready/Maintenance Mode is perfect for short or long term storage
and will never overcharge your batteries.
Note: Only the Green READY LED and the Blue AC POWER LED will remain on when
the ProSport is in its Ready/Maintenance Mode.
Performance Tip:
For long term or winter storage/ maintenance of batteries, ProMariner
recommends that every 30 days: AC power is removed by unplugging your extension cord at the
GFCI outlet first, check battery electrolyte levels. Re-apply AC power to your ProSport Charger.
This practice will properly maintain your batteries resulting in extended battery life and use.

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 caps.
Please be sure to keep your unused programming 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:

Selecting a Charging Profile & Understand Battery Types
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 high performance AGM or GEL batteries
simply remove the black programming cap and replace it with
either the red AGM HP or gray GEL 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 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.
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 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).
