The Model ProSport6 says;
Bank Config. Single
Total Amps Distributed 6 Amps
Use with # of Batteries 1
Battery System 12 VDC
The ProSport8, 12, 20 and 20 Plus have Dual and Triple config 2-3 battries 12/24/36 VDC depending on model.
I just assume since the ProSport6 say only 1 battery then the triclke 1.5 amp be the same. But, maybe those more knowlegdeable can make it work with one bank of 2 or more batteries. Myself, I would just try one with a simple trickle, I assume it not regulated.
I not know how to get a link. I typed;
Promariner 1.5 maintenance charger
into a Yahoo search and seen;
[PDF] PROMARINER PROSPORT MANUAL 1030
I clicked and learned, then try to share what the manual say. True, it not mention the 1.5 amp.
This link here;
PROMARINER PROSPORT 1.5 AMP PORTABLE MAINTAINER 10115
Does say Fully Automatic and it use batteries *Plural*

Gryzio-

When battery charger manufacturers say battery, they generally mean one battery electrically... .not necessarily a single physical battery.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

I still say you have a BAD battery, and need to test and start there first. IMOHO

And why would you think there is a bad battery?

This question has most likely been addressed here a number of times but I'll ask anyway. I'm looking for a solar system to charge a two bank of deep cycle sealed gel batteries with a regulator to avoid overcharging. The boat will be kept on a mooring so shore power is not an option and removing the batteries every weekend isn't all that appealing. The only items that will be run off them are the compass backlight, marine radio, depth sounder, cabin lights and power outlet for a blender or other such things. I have posted before and I really don't need sarcasm or offhanded remarks. So please if you have any experience or advise I would be very grateful.
Cheers,
PP

Let's see, a new sailboat for hours of fun and tranquility or my wife's new kitchen, ponder, ponder, ponder, what the hell I've got a grill on the boat!!!

Don't be afraid to start your own thread with questions like this!
Anyways, here is how I keep things topped up w/o shorepower.

ICP 10 Amp regulators can be had cheap, about $40 a piece. You can run two of them in parallel from one bank of solar panels to two battery banks. They work with gell-cell. Their internal circuitry protects them from reverse current. I don't know if ICP intended them to be used this way but it has been working great for me for at least 3 years. Two 55 Watt Siemens panels supply power to them, but you could get by with less. I wouldn't have invested in these for weekend use but luckily they came with the boat. Sounds like you aren't looking for loads of power. One 5 watt panel per battery would probably keep up charge with intermittent use if you live in sunny-ville.

IIRC, ICP made those small regulators for just this purpose.

Probably because the amount of current being drawn is enough to make the charger hot. If the charger was topping-off the batteries, the charging current would eventually go down to some very small amount--a fraction of an amp per battery--and the charger should cool down. But that doesn't necessarily mean "bad battery." It could also mean the charging current is never enough to get the batteries topped-off, so they continue drawing more than the charger can supply and the charger will keep overheating.

brak, if the charger really is "Designed to maintain 12 volt batteries up to 250 amp hours...," why are you trying to maintain 500AH worth of batteries on it?

If you'd seen the worn-out old UPS I once put under load literally shoot flames out the back when its solid-state components overheated and lost it, or any of the other number of solid-state electronics I've seen burst into flames over the years, you'd understand why I shun such conditions.

Particlepood,

My boat sits on a trailer and gets used typically one day per week and about once per summer for four or five days in a row. The electrical and power use is probably similar to your mooring. I did an xls spread sheet of my power generation and use - its here:

http://analogengineering.com/sail/sa...management.xls

The spread sheet tells me two things - can my 20 watt solar panel supply all my needs during the summer if I just use the boat one day per week (it does) and if I have fully charged batteries, how many days will my battery charge last.

FYI, the 20 watt solar panel has a charge regulator and I leave the batteries in the boat all winter. The place where the boat lives (in Colorado) is close to a lake which gets up to three feet of ice on it during the winter. I havnt had any issue with batteries doing this for five years now.

Waltsn...very nice spread sheet. I hope others here download it and use it to plan their systems out. Thanks.

The only quibble I have with the sheet is that you do not account for the self discharge of the batteries which can be as high as 1/2% per day with flooded batteries. In a winter storage or longer disuse situation, this becomes rather critical but cn be ignored for boats used every couple of weeks.

No longer posting. Reach me by PM!
