General Safety
Before connecting your batteries or applying AC power, read all instructions and cautionary
markings on the battery charger, cables, and batteries.
CAUTION - To reduce the risk of injury, charge only Lead-acid type rechargeable batteries;
Flooded (Lead-acid), Sealed (Lead-acid) and Gel (Gelled Electrolyte Lead-acid). Other
types of batteries may burst, causing personal injury.
Use of attachments not recommended or sold by ProMariner may result in a risk of fire,
electrical shock or personal injury.
EXTERNAL CONNECTIONS TO CHARGER SHALL COMPLY WITH THE UNITED STATES COAST
GUARD ELECTRICAL REGULATIONS (33CFR183, SUB PART 1).
Do not operate the charger if it has received a sharp blow, direct hit of force, been dropped
or otherwise damaged in any way. Do not install if any protective AC and DC cable insulation,
DC fuse holders and/or ring terminals have been damaged or compromised.
Call ProMariner for repair service to avoid risk of fire, short circuits or electrical shock.
Do not disassemble the battery charger. If service or repair is required please contact customer
care at 800.824.0524. Incorrect reassembly or cable modifications may result in a risk of
electrical shock, fire or explosion.
To reduce the risk of electrical shock, remove AC power from the charger prior to any
maintenance or cleaning.
WARNING: RISK OF EXPLOSIVE GASES
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 EXTREME IMPORTANCE
THAT EACH TIME BEFORE USING YOUR CHARGER YOU FOLLOW THESE SAFETY INSTRUCTIONS.
WARNING AVOID SERIOUS INJURY OR DEATH FROM FIRE, EXPLOSION, OR
ELECTRICAL SHOCK
- Make your AC power connection in an open atmosphere free of explosive fumes.
- Make your AC power connection in a secure manner that will avoid contact with water.
Personal Safety Precautions
a) Someone should be within the range of your voice or close enough to come to your aid
when working near a Lead-acid battery.
b) Have plenty of soap and water nearby in case battery acid comes in contact with skin,
clothes, or eyes.
c) Wear complete eye protection and clothing protection. Avoid touching eyes while working near battery(s).
d) 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 get
medical attention immediately.
e) NEVER smoke or allow a spark or flame in the vicinity of a battery or engine.
f) Incorrect assembly or modification may result in risk of electrical shock, fire, or explosion.
g) Be extra cautious to reduce risk of dropping a metal tool onto the battery. It might spark
or short-circuit a battery or other electrical hardware which may cause an explosion or fire.
General Safety
h) Remove all personal metal items such as rings, bracelets, necklaces, watches, and jewelry
when working near a battery. A battery can produce a short circuit current high enough to
weld a ring or any other metal, causing serious burns.
Not intended to supply low voltage electrical systems other than in a marine application
use your marine battery charger to charge dry cell batteries that are commonly used with home
appliances. These batteries may burst and cause injury to persons and property. Never charge
a frozen battery.
. Do not
Safety Precautions Prior To Charging Batteries
If necessary to remove a battery from a boat to charge, always remove the grounded
negative terminal from the battery first. Make sure all accessories in the boat are off,
as to not cause an arc. Be sure the area around the charger and batteries is well ventilated
while the batteries are being charged. Gases can be forcefully blown away using a piece of
cardboard or other nonmetallic material as a fan.
Clean battery terminals with full eye protection to prevent corrosive material from coming in contact
with eyes.
For flooded batteries add distilled water in each cell until electrolyte reaches levels specified
by the battery manufacturer. This helps purge excessive gases from cells. Do not overfill. For
batteries without caps, carefully follow manufacturer's recharging instructions.
Study all manufacturer’s specific precautions, such as removing or not removing cell caps
while charging, in addition to battery type for proper rate 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 to a nearby 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, completely disconnecting
IMPORTANT NOTICE: FCC CLASS A PART 15 NOTIFICATION
Your On-Board Marine Battery Charger has been designed and tested to comply with FCC Class A
part 15. These regulations are to provide adequate protection against harmful interference while
operated in a commercial application. If in a residential setting, you are encountering interference
with TV and radio reception, simply remove AC power from the ProMariner unit to confirm if your
battery charger is causing interference. End user can explore the following to minimize interference:

General Overview
The ProMar1 Battery Charger is a fully Automatic/ Electronic On-board Marine Battery Charger.
The unit is prewired for easy installation and is 100% waterproof for fresh and salt water
applications.
The ProMar1 charger incorporates a durable one piece plastic housing. The unit offers fully
automatic charging which includes a "Float " maintenance mode that is safe for long and
short term storage. The charger can be left on indefinitely without harming or over charging
your batteries.

engine battery (model specific) configurations without rewiring or switching. Just attach the
DC output cable terminals as illustrated in the installation section of this manual.
Understanding Battery Types
There are three primary types of batteries; 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.
NOTE: AGM (Absorbed Glass Mat) batteries are not Gel (Gelled Electrolyte Leadacid) batteries. AGM batteries are charged with a completely different charge profile
when compared to Gel batteries.
For use with Flooded (Lead-Acid) or Gel Batteries. Not for use with AGM (Absorbed
Glass Matt) or 4D or 8D large capacity batteries.
***If you are unsure as to what kind of battery you have, we recommend that you contact
the manufacturer of the battery.
