Re: Stus-List Batteries -- Flooded, Sealed or AGM?

[Bill Bina - gmail via CnC-List]

I have two group 27 AGM's on my boat. One is the house, and one is for 
starting. AGM's have lower internal resistance than flooded batteries, 
which mean they accept a charge more easily, and they also can provide 
the extra current for starting without breaking a sweat. They have thin 
plates, but unlike a flooded battery, they are completely supported by 
the glass mat between them. That makes them immune to the vibration that 
can kill flooded batteries including deep cycle versions. They are also 
immune to the instant onset of sulfation when dropping water levels 
expose the plates in flooded batteries to air. I am on a mooring and the 
batteries are always charged to 100% with just the use of a 20 watt 
solar panel and a Genasun MPPT controller. My only other charging source 
is the alternator in my Yamaha outboard. The same setup with flooded 
batteries had trouble reaching full charge. I do not find charging them 
at all tricky. They have different needs than other types, but it really 
is not at all complicated to provide what pleases them.

Re: Stus-List Batteries -- Flooded, Sealed or AGM?

[Rick Brass via CnC-List]

Josh;

 

The off gassing from a battery is primarily:

 

1)  Water vapor as the water evaporates with heat. This happens even
when not charging (to a very small degree) on days when the relative
humidity in the air is low. But then low relative humidity is a pretty rare
event in the air around a boat that is in the water. In most flooded
batteries this water vapor is condensed in the caps and drips back into the
cells.

2)  Hydrogen gas that is released when the SO4 part of the sulfuric acid
bonds to the lead plates as a result of high temperatures while charging or
as the plates sulfate during longer periods of storage.

3)  Hydrogen and oxygen gas from electrolysis at higher charge rates.

 

Electrolysis isn't usually much  of a factor at normal charge rates.

Listers,

 

As you know, I'm redoing the electrical systems on the
Enterprise (thanks to all for diagrams and advice). 

 

So now comes the question of what type of battery to use in my
house bank - Flooded, Sealed or AGM? What do you have on your C&C and why do
you prefer it? 

 

And, if you have flooded, how often do you top them off with
distilled water? 

 

The countdown has begun!

Re: Stus-List Batteries -- Flooded, Sealed or AGM?

[Rick Brass via CnC-List]

Edd;

 

Like several others, I would endorse the choice of going with golf cart
batteries (I'd use GC5s, not GC2s, but I'd have flooded golf cart batteries
in my boats if there was enough room in the locker that the batteries are
housed in to accommodate the height of the batteries.

 

You have raised the question of the batteries freezing. A fully charged wet
cell battery has a freezing temperature of 76 degrees below zero Fahrenheit.
It is true that the liquid in a flooded battery that is fully discharged is
around 30 degrees, since the liquid is almost 100% distilled water. But I
don't think I've ever seen a frozen battery - even is a winter stint at the
GM Arctic Proving Grounds years ago. Unless New Jersey is expecting an Ice
Age, I wouldn't worry.

 

Storage on the boat over the winter is also not a real problem - although
there are a lot of old wives' tales about taking batteries home for storage
and not setting them on concrete floors, and so forth. The accepted
self-discharge rate for a lead-acid battery is between 1.5 and 3% per month,
depending on storage conditions. The rate gets higher as the storage
temperature gets higher, but isn't really very high until you get over 100
degrees. AGM batteries are a bit less, but the chemistry is almost the same
and the lower rate for an AGM battery has more to do with the fact that the
AGM has less plate surface area in contact with the electrolyte mat, so the
reaction is slower.

 

You may want to think about how you use your boat when you make the decision
about batteries. You mention wanting 4 to 6 T-105 batteries in your house
bank. That's 450 to 675 AH in a 12 volt configuration, and that gives you a
lot of live aboard time. My 460 AH house bank will power my 38 for 2 to 3
days on the hook without recharging. (My biggest draw is for refrigeration
and that is more than half of the total.)

 

But  if I recall you mostly daysail and race, so what impact will 400 pounds
of batteries have on trim and performance? Do you need that much endurance?
Also, you say you only charge with your engine alternator. A 675 AH bank is
going to need a 75 amp (or more) alternator and a smart voltage regulator to
recharge it in any manageable amount of time, and at least a 60 amp charger
if you plug into shore power.

 

I have many years of experience in the marketing of batteries for industrial
vehicle, and I have an aversion to AGM batteries, so I'd recommend not using
them. YMMV.

 

Sure, you can lay them on their side. But laying your sailboat on its side
is slow, and flooded batteries - particularly the maintenance free versions
- don't generally leak liquid at normal angles of heel for reasonable
lengths of time.  AGM batteries are more demanding about proper charging
voltages (the regulator in your boat is almost certainly designed for
flooded cells, not AGMs, and will need to be replaced) and less forgiving
about being stored when partially discharged than flooded cells. And AGM
batteries have a significantly shorter service life - in terms of
charge/discharge cycles - than do flooded batteries. Plus they are a lot
more expensive.

 

I looked at the AGM batteries in your post. Trojan T125s from the same
supplier would have 15% more capacity and cost 15% less than the AGM. Two
Exide or Interstate 27 deep cycle batteries in parallel would have the same
capacity as two of these AGM GC2s wired in series and cost about half as
much.  These particular AGM batteries don't look like a particularly good
value to me.  

 

Good luck making your decision

Josh,

 

I'm leaning towards 4 to 6 (depending on the space available)
Trojan T-105s, but am concerned about the maintenance, especially since I'm
kinda cut off from the boat all winter long. Alternatively, I was looking at
these AGMs:

A2g, but won't bother if AGMs are only going to last a few years. 

 

My charging system is the alternator, since the Enterprise lives
on a mooring during the season (yes - we call that "standard orbit"). I only
hook up to shore power a few times a year when cruising. 

 

The new system will connect the alternator to the house bank and
use a Blue Seas ACR

All,

Been seeing a lot of write-ups on gassing, tilting, refilling and other 
concerns to keep me away from flooded batteries. 

I already have an AGM 12V on board, which I’ll use for my starting 
battery, and then add 4-6 (depending on space - which, of course, is the final 
frontier) 6V AGM batteries like these: 
http://www.atbatt.com/amstron-gc2-6v-agm-deep-cycle-battery.asp?utm_content=Amstron-AP-GC2&utm_term=AP-GC2&utm_category=Sealed-Lead-Acid&gclid=CLy95KfH_cMCFXBp7Aod2WkA2g
 

 

Thanks to all for the links and advice. Truly a great list. 


All the best,

Edd

Re: Stus-List Batteries -- Flooded, Sealed or AGM?

[Joe Della Barba via CnC-List]

Wet cells definitely can emit corrosive acid fumes. My wife's car battery
does this, it gets the nasty sulfur-metal-acid crystals all over the battery
connections. I solved that by spraying them with engine fogging oil.

You have some form-factor issues with wet vs. gel/AGM. A wet cell needs to
be in a battery container that can hold spilled acid. A gel/AGM cannot leak
and you could even cut it in half and use the half that still had the
terminals. The 35 MK I can fit a 4D into the battery space, but not a 4D in
a container, so if you want to go that way a wet battery is out. We once did
have a wet battery not in a case and it cracked in half during a hurricane
and leaked acid into the bilge. That was not a nice smell - sulfur and
chlorine gas :(

Speaking of battery size, "golf cart" is not always a wet cell. You can get
them in gel and AGM too. Two golf carts are a LOT easier to move around than
one 8D and the AHs are about the same. You also can fit 3 group 24s in an 8D
case.

Listers,

 

As you know, I'm redoing the electrical systems on the
Enterprise (thanks to all for diagrams and advice). 

 

So now comes the question of what type of battery to use in my
house bank - Flooded, Sealed or AGM? What do you have on your C&C and why do
you prefer it? 

 

And, if you have flooded, how often do you top them off with

Re: Stus-List Batteries -- Flooded, Sealed or AGM?

[dwight veinot via CnC-List]

I use much the same procedure that Robert described with my wet cell Great
Northern batteries (2 six V golf cart and 1 group 24, all deep cycle, group
24 used mostly for starting and backup)...in fact Robert may have started
using this procedure after discussing with me...my batteries have remained
onboard ever since I got them about 9 years ago...one other inportant issue
though is to check electrolyte level in fall before that winterizing
charge...if it's low and especially if you can see that any plates are not
covered with electrolyte then replenish with distilled water before
applying the charge...and another  guideline that I find useful as an
indicator is that if in spring after having done absolutely nothing to the
batteries all winter long, a battery has not held most of its charge then
it is likely time to get a new battery...the voltages that Robert reported
measuring in his batteries just lately are characteristic of good lead acid
batteries and about what I would expect to see in my batteries come spring,
maybe a bit lower to around 12.4 but not much if the battery is good.  Such
batteries have started my little M4-30 diesel each spring without further
charging but I will apply a 24 hour slow charge to each before launch. I do
not have shore power so the only charging my batteries see during the
sailing season comes from my alternator...after 9 years on these batteries
no problems yet...I still have incandescent lights throughout and I run an
Adler barbour refrigerator while cruising but not continuously...I also add
ice to my ice box when it is available and we start all cruises with frozen
fresh drinking water in the ice box and frozen meets as well.  Works good
for us in August here in Nova Scotia.

Not sure you can attribute that corrosion to off-gassing from your
batteries...what gases do you think cause this corrosion?  Off gassing from

Re: Stus-List Batteries -- Flooded, Sealed or AGM?

[Jake Brodersen via CnC-List]

Edd,

 

I prefer AGM.  No noxious gases to be vented into the cabin.  I have a lot of 
corrosion on my electrical panel that I directly attribute to being bathed in 
off-gassing from old batteries.  Plus, they’re safer from an explosion 
perspective, as well as if you ever end up inverted for a short period of time.

Listers,

 

As you know, I’m redoing the electrical systems on the Enterprise 
(thanks to all for diagrams and advice). 

 

So now comes the question of what type of battery to use in my 
house bank — Flooded, Sealed or AGM? What do you have on your C&C and why do 
you prefer it? 

 

And, if you have flooded, how often do you top them off with 
distilled water? 

 

The countdown has begun!

I selected AGMs because they don't release gas and are supposed to still work 
on their sides. Mine are located under the aft bunk aligned port to starb. 
Expensive but tough and reliable, have lasted 10 years for me.

Maine Sail has this one covered too. Wet cells won't leak (until you have 
already capsized and then you have bigger problems) if the are oriented the

I installed a 50W solar panel last summer to keep batteries topped off at the 
mooring.  I bought one sized to fit the sliding companionway hatch.   I ran the 
wires to a 12v outlet plug near the start panel and from there to a charge 
controller mounted in the lazarette.   I leave it just sitting on the hatch 
when gone and unplug it and throw it on the rear mattress when I get to the 
boat. It is heavy enough that it is not going anywhere short of a serious gale, 
but light enough that it is easy to move around.  It worked great last season 
and well worth the time investment to get the wiring installed.  Dave

One thing to keep in mind is wet cells can lose up to 10% of charge per month 
and gels only lose around 1%. For a boat on a mooring or otherwise off shore 
power this can be a factor.

Re: Stus-List Batteries -- Flooded, Sealed or AGM?

[Kevin Driscoll via CnC-List]

Keep in mind that most racing rules prohibit use of wet cells for obvious
reasons. Knot sure what Maine Sail has to say about defying specific
gravity when pinned on a knock down or round down. (I believe most of what
Maine Sail has to say, but not all...)

Here is another guy in Maine with a more forward looking view.

Re: Stus-List Batteries -- Flooded, Sealed or AGM?

[Marek Dziedzic via CnC-List]

Michael,

maybe with Lithium (Li-ion), batteries; I don’t think with NiCd.

There are a few write-ups on the use of Li-ion batteries for sailing 
applications. If I recall correctly, you get almost double density (Ah/weight) 
and you can easily reach 80 % of discharge (without any damage); this means 
that you need almost 1/4 of the weight and 1/2 of capacity. The price is 
somewhat high still, but if you spend a lot of time without being able to 
recharge, they might offer the right value. The flip side to that is that you 
better have a really good charge controller.

Re: Stus-List Batteries -- Flooded, Sealed or AGM?

[Eric Frank via CnC-List]

Ed,
But it takes only a small panel to provide adequate current to keep them topped 
off. You will need your alternator when using the batteries for cruising, of 
course, but sitting on the mooring, even 0.5 - 1 amp is sufficient.  That's all 
I use on Cat's Paw (kept on a mooring); I have a small solar panel on the 
forward hatch.  Even with a small panel, though, I recommend a simple charge 
regulator to stop the charging when the batteries are topped up.

I may be new to sailing but not to boats. My last boat had (3) 12V starting 
batteries and (2) 6V (in series) for the house bank. All deep cycle wet cell 
varying in age from one to six years. My current boat has only (2) 12V (age 
unknown) with nothing to charge them but the A-4. I have never experienced any 
amount of self discharge to the point of concern over any reasonable amount of 
time. I have always kept them on the boat over the winter and top them off and 
check fluid level in the beginning of the season. Last year I didn’t even do 
that and both engines (1970 GMC 427 Mercruisers) cranked over plenty strong 
after a winter on the boat. (that was right before I sold her and got my C&C 33)

 

A agree that the predictions of self-discharging over time have never in my 
experience come to pass.

 

In response to the concern of spilling acid in a wet cell on a 
rail-in-the-water-heel, I think they made sealed no maintenance wet cell 
batteries. They do for uninterruptible power systems (UPSs). Airplanes, too I 
think. I will have to look into that. The old boat didn’t tip that much.

Edd,

 

I am not claiming to be an expert, but from what I have read so far, the AGMs 
might be a costly solution to a somewhat non-existing problem.

 

Check Main Sail’s write ups on batteries (he did a few additional ones 
recently). If I understand these things correctly, the best performance per $ 
you will get from the wet cells (proper marine deep cycle ones). The longest 
duty cycle – from the golf batteries (the main disadvantage – they are higher 
than most other batteries, but this is for a reason – there is extra 
electrolyte over the plates and they don’t get uncovered when the boat heels). 
The most convenient – gel cells (few disadvantages of AGMs and most of the 
advantages of wet cells plus they don’t spill, don’t have issues with heeling 
angle and can be placed safely in the cabin). AGMs would require special care 
(when charging) and may not last that long.

Re: Stus-List Batteries -- Flooded, Sealed or AGM?

[Michael Brown via CnC-List]

I would advise an AGM, maybe as the starting battery and for emergencies,
simply in case of a knockdown or other rare event.

My background with AGMs is from the computer industry were the are used
in Uninterruptible Power Supplies ( UPS ). Overall I was not and still am not
impressed. The high quality units are about $80 for a 12V 18 - 20 AH battery.
Even in the situations were they are in a "perfect" temperature controlled and
vibration free environment, tended by an exotic and expensive charger they
typically only last 5 years and 2 - 3 full uses. The UPS will do a run down 
test,
which can be automated monthly, and a battery test weekly. So only once
a week the UPS will kick in and run from battery for a couple of minutes,
and once a month it will partially discharge ( configurable 30 - 70% ) the
battery and measure the actual AH available.

A golden life for a battery I would think, and as a guess about
50% of the UPSes get the battery pack changed around 3 years.
Some are still working, but from the monthly run down test have lost
too much capacity. Sometimes even with identical batteries bought at
the same time and run exactly the same one battery will die. So I end
up replacing all of them.


I had hoped that with the research and work being done on the larger
NiCD packs in hybrid cars that marine NiCD wet cells would become more
common.

[Marek Dziedzic via CnC-List]

I would like to add to what Joe said that if you don’t have the shore power, 
you do need some additional way of charging the batteries. The alternator alone 
would not be able to do the job, unless you motor extensively (and then you 
might question why you are carrying that stick pointing up from the deck or the 
3000-500 lb. of lead under the hull). This applies to any kind of battery, 
almost regardless of chemistry and technology. Probably even more to AGMs, 
because they hate to be left at a discharged state for any longer period.

One thing to keep in mind is wet cells can lose up to 10% of charge per month 
and gels only lose around 1%. For a boat on a mooring or otherwise off shore

I’m leaning towards 4 to 6 (depending on the space available) Trojan T-105s, 
but am concerned about the maintenance, especially since I’m kinda cut off from 
the boat all winter long. Alternatively, I was looking at these AGMs:

 but won’t bother if AGMs are only going to last a few years. 

 

My charging system is the alternator, since the Enterprise lives on a mooring 
during the season (yes — we call that "standard orbit"). I only hook up to 
shore power a few times a year when cruising. 

 

The new system will connect the alternator to the house bank and use a Blue

(https://www.bluesea.com/products/7610/SI-ACR_Automatic_Charging_Relay_-_12_24V_DC_120A)

Re: Stus-List Batteries -- Flooded, Sealed or AGM?

[Della Barba, Joe via CnC-List]

One thing to keep in mind is wet cells can lose up to 10% of charge per month 
and gels only lose around 1%. For a boat on a mooring or otherwise off shore 
power this can be a factor.
If you go wet cells on a mooring you will want a solar panel to keep them 
topped off.

Edd,

I am not claiming to be an expert, but from what I have read so far, the AGMs 
might be a costly solution to a somewhat non-existing problem.

Check Main Sail's write ups on batteries (he did a few additional ones 
recently). If I understand these things correctly, the best performance per $ 
you will get from the wet cells (proper marine deep cycle ones). The longest 
duty cycle - from the golf batteries (the main disadvantage - they are higher 
than most other batteries, but this is for a reason - there is extra 
electrolyte over the plates and they don't get uncovered when the boat heels). 
The most convenient - gel cells (few disadvantages of AGMs and most of the 
advantages of wet cells plus they don't spill, don't have issues with heeling 
angle and can be placed safely in the cabin). AGMs would require special care 
(when charging) and may not last that long.

You may find interesting the results of the battery survey Main Sail did 
recently. Here is the link to his "early results": 
http://forums.catalina.sailboatowners.com/showthread.php?t=168972. Or his take 
on the flooded deep cycle batteries here:

Josh,

I'm leaning towards 4 to 6 (depending on the space available) Trojan T-105s, 
but am concerned about the maintenance, especially since I'm kinda cut off from 
the boat all winter long. Alternatively, I was looking at these AGMs: 
http://www.atbatt.com/amstron-gc2-6v-agm-deep-cycle-battery.asp?utm_content=Amstron-AP-GC2&utm_term=AP-GC2&utm_category=Sealed-Lead-Acid&gclid=CLy95KfH_cMCFXBp7Aod2WkA2g,
 but won't bother if AGMs are only going to last a few years.

My charging system is the alternator, since the Enterprise lives on a mooring 
during the season (yes - we call that "standard orbit"). I only hook up to 
shore power a few times a year when cruising.

The new system will connect the alternator to the house bank and use a Blue 
Seas ACR 
(https://www.bluesea.com/products/7610/SI-ACR_Automatic_Charging_Relay_-_12_24V_DC_120A)
 to also charge the starting battery. That means I'll have a New-In-Box Echo 
Charger to sell this Spring.

All the best,

Edd

Re: Stus-List Batteries -- Flooded, Sealed or AGM?

[robert via CnC-List]

Edd:

We have two Great Northern Group 27 wet cell batteries that are left on 
board all winter.these two batteries get a full charge late in the 
Fall and sometimes a short charge (one hour) at 6 amps during the winter 
and that's it.  They have seen 6 sailing seasons, have spent every 
winter on board, and last week I  went to check the boat, mostly for the 
build up snow and ice on the shrinkwrap, my volt meter said one battery 
was 12.59V the second was 12.57V.  My point is, if fully charged in the 
Fall, there is very little, if any, winter maintenance involved.


A side story.got on a step ladder to board my boat last 
week.didn't realize there was 2 inches of solid ice lying on the 
white shrinkwrap directly above me.when this approx. 3' x 3' piece 
of solid ice started to slide towards me, I got my head and shoulders in 
the gate/companionway just in time before it decapitated me and/or 
removed all my front teeth.  Lesson learned... won't do that again, he says!

Re: Stus-List Batteries -- Flooded, Sealed or AGM?

[Frederick G Street via CnC-List]

Edd — +1 on golf cart batteries, specifically the Trojan T105.  If your 
charging system is set up and controlled properly, you shouldn’t have to top 
them off very often at all.  I’ve had a set in my boat for over five years now 
with no issues, and no apparent drop in capacity.

  Listers,


  As you know, I’m redoing the electrical systems on the Enterprise (thanks to 
all for diagrams and advice). 


  So now comes the question of what type of battery to use in my house bank — 
Flooded, Sealed or AGM? What do you have on your C&C and why do you prefer it? 


  And, if you have flooded, how often do you top them off with distilled water? 


  The countdown has begun!

  All the best,


  Edd

I use Delco Voyager maintenance free wet cells, Series 29's.  Get 5-7+
years service life.
