Frequently Asked Questions - Promariner
Q.
How much charging time is available per day, either with shore power or generator power?
A.
A 20 amp unit will average 20 amps per hour. Twelve hours of charging time will equal near 240 amperages returned to battery.
Q.
How many batteries or battery banks are to be charged?
A.
A bank is several batteries harnessed together and treated as if they were a single, larger battery. Your charger will require one output per bank. Chargers often have a number of outputs, some which need not be used. Some have 1 or 2, most have 3 or more units.
Q.
What is the type, usage and total amp hour capacity of your batteries? (Examples: #1-one 205 amp 8D for engine start, #2-one 205 amp 8D for engine start, #3-four 250 amp 6 volt golf cart-house, #4-one 85 amp gel cell for generator start)
A.
This figure is usually expressed as a “20-hour rating.” Fast or quick chargers should not exceed 20% of this rating for normal batteries or 30% for golf cart or specialty batteries.
Q.
What is your average hourly DC load (24 hours)? (Example: Fridge runs for 20 minutes out of every hour at 12 amps = four amps average load.)
A.
This is the total of all equipment loads: lighting + refrigeration + pumps + motors, etc. Intermittent loads, such as 12V DC refrigerators which cycle on and off, should be averaged out over their duty cycle.
Q.
How quickly do you need to recharge and to what percent of full charge – 80% or 100%?
A.
Batteries need to be kept fully charged (to 80% is okay for two or three weeks of cruising). Normal alternators and battery chargers reach 70% of full charge fairly quickly, but take longer than “fast” chargers to charge that last 30%. The new technology multistep chargers will recharge your batteries 100%.
Q.
What type of batteries – flooded, lead/acid, gel, agm, etc.?
A.
Chargers are field adjustable to meet manufacturer’s specs, or Professional Mariner will customize a unit for your requirements.
Q.
What are the different types of batteries?
A.
Here are the different types of batteries you can purchase:

Lead-acid batteries

Requires maintenance.

Liquid electrolyte that needs to be periodically checked and filled with distilled water (as needed). Has to be mounted upright (will leak through caps if mounted in any other position).
Considered hazardous material.
AGM absorbed glass-mat batteries

Maintenance-free.

Sealed battery that has all of its electrolyte absorbed in fiberglass separators consisting of a sponge-like mass of matted glass fibers. Operates under pressure to force the hydrogen and oxygen gases produced during charging to recombine into water, eliminating the need to periodically add water to the battery. Spill-proof, leak-proof, can be mounted in any position and can be shipped via regular freight carriers.
Gel-cell batteries

Maintenance-free.

Sealed battery that uses gelled electrolyte technology. Operates under pressure to force the hydrogen and oxygen gases produced during charging to recombine into water, eliminating the need to periodically add water to the battery.
Spill-proof, leak-proof, can be mounted in any position and can be shipped via regular freight carriers.
Q. What types of batteries can your chargers handle?
A. You can use any of the above battery types on our chargers. Our chargers are factory set for lead-acid batteries. The settings depend on the type of charger (different models may have different settings), but most of our chargers have a lead-acid and a gel-cell setting. AGM batteries will charge at the lead-acid setting (NOT the gel setting).
Q.
Can my 12 volt charger charge my 24-volt or 36-volt battery system?
A.
Our waterproof chargers are designed to charge 12-volt batteries within a 12/24/36 volt system. If you have a Dry Mounted battery charger (ProTech, Flyback, Promatic) then you would need a 24-volt charger for a 24-volt system or a 36-volt charger for a 36-volt system. A 12-volt non-waterproof charger cannot charge a 24-volt or 36-volt system…….the charger has separate positive terminals but only one common negative terminal (so the battery banks are not isolated from each other).
Q.
Can I connect the charger to only one battery? What do I do with the unused terminals?
A.
On a Dry Mount charger, you will need to jumper the unused positive terminals to one of the positive terminals that you are using so that the charger will “read” a battery on each lead.
Q. Where can I mount the charger?
A. Make sure you have adequate ventilation for cooling of the charger, but these chargers are not made to get wet and it will Void the warranty.
Q. My charger is tripping my GFCI circuit breaker on my outside outlet?
A. All chargers that use this technology to charge batteries bleed a little voltage, which should be below the GFCI trip point. Test the charger on a non-GFCI outlet (inside the house) and see if the charger works. If it works, then most likely something is wrong with the GFCI outlet. If it does not work on an inside outlet, then there is something wrong with the charger.
Q. Can my charger be left on for an extended period of time?
A. The newer 3-step chargers have a float mode (3rd step) which maintains the batteries at 13.3 volts (for lead-acid batteries) and 13.8 volts (for gel-cell batteries). As long as the batteries are in good condition and you maintain your water levels inside the batteries periodically (for lead-acid batteries), then you can leave the charger on between fishing, boating trips, etc.
Q. What charger setting do I have to use for AGM batteries?
A. AGM batteries can charge at the lead-acid setting on our battery chargers. Our chargers are factory set for lead-acid so you do not have to make any changes to the charger.
Q. Can I charge a lead-acid battery and a gel-cell battery together?
A. Our chargers charge and float lead-acid batteries at a different voltage than gel-cell batteries. You should not mix battery types because you are going to compromise a battery if you charge it at the wrong setting.
Q. What is the difference between the older Ferro-Resonant chargers and the newer 3-step chargers?
A. The older Ferro-resonant chargers were constant volt chargers that put out 13.8 volts. They did not charge at a high voltage and then step down the voltage for a maintenance mode. They are much bigger and heavier and most often louder.
Q. How long will it take to charge my batteries?
A. The following equation will give you a good idea of how long it will take to charge batteries.

Total Amp Hour capacity of the batteries
————————————————
Total amperage output of charger

= Total Hours To Charge Batteries

Example: 100 amp hour battery / 10 amp charger = 10 hours

If you drain your battery half-way (50%) then you would need to put 50 amps back into it. Based on the above equation it would take you 5 hours to charge the battery.

If you have more than one battery, you will have to add up the amp hour capacity of all the batteries and then divide by the total amp output of charger to get charge time.

v Waterproof Battery Charger FAQs
Q.
How hot is my charger supposed to get?
A.
If it is a waterproof charger (ProTournament, ProSport, ProSport Generation 2, XPS or ProMite), it does not have external fans on it. It dissipates heat through the casing, so it does get warm to the touch. Most often we describe temperature as: you can touch the charger, but you would not want to carry it across the room.
Q.
How do I wire the charger to my 24-volt or 36-volt battery system?
A.
Our waterproof chargers are designed to charge 12-volt batteries within a 12/24/36 volt system. If you have a waterproof battery charger (ProTournament, ProSport, ProSport Generation 2, BassMaster, ProMite or XPS) and you want to connect it to either a 24-volt or 36-volt system, just connect one set of leads (positive and negative) to each battery in the system (the leads are fully isolated from each other). You do not have to disconnect the jumper that connects the positive from one battery to the negative of another battery. The same goes for batteries in a 12-volt system…..just put one set of leads (positive and negative) on each battery. So a 2 bank charger charges 2 batteries, and a 3 bank charger charges 3 batteries.
Q. Can I connect the charger to only one battery? What do I do with the unused leads or terminals?
A. If you are using a waterproof charger and want to charge 1 battery on a 2 bank charger, you will need to connect both leads on that one battery. If you are charging 1 or 2 batteries with a 3 bank charger, you will need to connect all the leads on the 1 or 2 batteries. At no time should the charger be run without all the leads being connected to a battery(s).
Q. Where can I mount the charger?
A. Make sure you have adequate ventilation for cooling when charging. It can be mounted in any direction; it can even be mounted on the underside of a hatch, or any wall that you have enough room (as long as it is mounted as far as possible from the batteries or fuel tank). Don’t mount them on carpets—if you have no other location, mount it on either a board or with some kind of spacers to lift the charger off of the carpeted area. If the charger is mounted in an enclosed space it is best to open a hatch during the first stage of charging.
Q. My charger is tripping my GFCI circuit breaker on my outside outlet?
A. All chargers that use this technology to charge batteries bleed a little voltage on the ground, which should be below the GFCI trip point. Test the charger on a non-GFCI outlet (inside the house) and see if the charger works. If it works, then most likely something is wrong with the GFCI outlet. If it does not work on an inside outlet, then there is something wrong with the charger.
Q. Can my charger be left on for an extended period of time?
A. The newer 3-step chargers have a float mode (3rd step) which maintains the batteries at 13.3 volts (for lead-acid batteries) and 13.8 volts (for gel-cell batteries). As long as the batteries are in good condition and you maintain your water levels inside the batteries periodically (for lead-acid batteries), then you can leave the charger on between fishing, boating trips, etc.
Q. What charger setting do I have to use for AGM batteries?
A. Most AGM batteries can charge at the lead-acid setting on a battery charger. Our chargers are factory set for lead-acid so you do not have to make any changes to the charger.
Q. Can I charge a lead-acid battery and a gel-cell battery together?
A. Our chargers charge and float lead-acid batteries at a different voltage than gel-cell batteries. You should not mix battery types because you are going to compromise a battery if you charge it at the wrong setting.
Q. What does it mean if I have a blinking light?
A. If you are getting blinking lights there are two things that could be going on.1. There could be a problem with your charger.2. There could be a problem with your batterie(s) (even if they are new).The first thing to check is to see that the polarity (negative and positive) has not been reversed. If they are set up correct, then disconnect the leads from the batteries and with the end of the leads not touching anything turn the charger on. You should get a solid green light and the output of the charger should be 13.3 volts. If the light(s) still blinks then there is a problem with the charger. If you get a solid green light the next step is to isolate each of the batteries, by doubling up the leads on one of the batteries. Repeat this until you have isolated each of the batteries. If it blinks on all combinations of the batteries, then there is a problem with the charger. If it blinks on one of the batteries, then that battery is the problem.
