Hi

I bought the two Nautaulis deep cycle big batteries for 139. ea. Also the
motomaster 10/2 amp automatic charger regurlarily 70.

I have had the 2amp charger on one of the batteries for about 6 hours or 8
hours and little bubbling going on I can hear and the charger still is not
changing from red light (charging) to green light (charged).

Should I keep it on the 2am for longer? Batteries are only 1 week old from
Canadian Tire and charger is also new.

Is the bubbling a concern? It is not boiling over, but listening very close
you can hear the bubbling.

Nobody at any of the branches could give me any real advice. I wanted to
treat these batteries with kid gloves so they would last more than 4 years.

Any advice or help would be greatly appreciated,,, thanks

Got a digital voltmeter? They're only $4 at the Chinese cheap tool
stores and are very accurate. With the charger running, you should not
see over 14.8VDC at the battery terminals. You must be awful close if
it's bubbling loud enough to hear. Don't leave it on bubbling so you
can hear... Modern batteries not being overcharged use almost no water
over long periods of time. If you have to refill the battery very
often, you're overcharging it.

While you're foraging for a DVM, buy a temperature compensated
hydrometer, not the cheap crap with the floating colored balls, one that
has a real thermometer buried in a rubber housing from the NAPA store or
where mechanics buy auto parts. That's the ONLY way to tell what
condition your battery cells are in. When it's charged, the specific
gravity, compensated for temperature of the electrolyte which is the
only way to get an accurate reading, should be 1.270 sp gr. All the
cells should be within .005 sp gr of each other. If you find a low
cell, way off from the others...bad battery needs replacment under
warranty. It does happen.

Remember, batteries are only refilled with PURE DISTILLED WATER, not
spring water, city water or that crap in the hose on the dock....(sigh)
Distilled water is available at grocery stores to put in clothes irons.
Make SURE it says STEAM DISTILLED, not just demineralized by pouring it
through a cheap filter gadget.

Hi Larry

Thanks for the reply and expertise,,

I do not have a dvm or specific gravitity measurer.

So I should shut it off now because it is lightly bubbling on the 2am charge
because it has not reached the capacity point where the automatic shut off
should have shut off. I tried it on an old 12v deep cycle and it did charge
it quickly (maybe an hour) and green light came on. But these two new ones
which are larger in size and weight are not shutting off the automatic
charger yet. I am a bit reluctant to charge it in the 10amp. The folks at
the C.T. told me to bring in the batteries and they will put a 30amp on them
and have them topped up in minutes but I did some reading and that can't be
too good for the deepcycle batteries.

Without the dvm or hydrometer I cannot really do much as I will need to know
the condition of battery and maximum charge coming off that charger.

I will look for those tools,

thanks

I agree with this... I'd be very concerned about bubbling and temp rise.
I've never been able to actually hear any bubbling, although small bubbles
do form and I can see them if I take a look. Make sure everything is OFF
(and I mean EVERYTHING) and wear eye protection if you decide to open the
fill holes. Obviously, you want to ensure nothing metal comes in contact
with the terminals. A friend of my father's died from a car battery
explosion.

I'd turn off everything, get a volt meter, and try again. Check the water
level before you restart the charging, and if it's low, I'd be even more
concerned.

I don't think one charge like this would do much harm if you decide to have
them do it. They're under warranty, right? Make sure you document when this
is done, then if there's a problem, you've got some leverage.

After, I would monitor the batteries condition closely for a few weeks, then
check them regularly thereafter.

What about leaving the charger on overnight?

The battery hasn't shut off the 2amp automatic charger yet and its only been
about 8 hours. Could or should i try leaving it on the 2amp auto off, sure
it is light bubbling as i can hear it, and see what it looks like in the
morning.

If battery light shows red and continuing charge, then return the batteries
and charger to C.T. and explain and have them test and replace as necessary
as this is simply normal operations and they said do it anyway.

If battery light shows green then all should be good to go.

I just worry about hearing the light bubbling and know it would go on all
night. I read somewhere the bubbling wasn't good for the deepcycle plates
and reduces their efficiencies and capacity.

I gots to know.

Lite bubbling is normal, but like I said, I've never heard it just seen it.

You need something more precise than red and green lights. The best
way is with a load tester which you can buy at a reasonable price from
Harbor Freight or Northern Tool. Also, as Larry mentioned, a specific
gravity test using a hygrometer is very useful. Last but not least,
test the battery with a DVM after it has been off the charger for at
least 24 hours. A fully charged battery should read about 12.6 volts
with no load or lightly loaded.

random thoughts:

Its hard to say about the bubbling because a small amount of bubbling is
expected, but a large amount means possible overcharging. As others
say, get a simple Voltmeter and a cheap specific gravity tester - you
can get both for under $10. And of course make sure the battery has the
proper amount of distilled water.

Your batteries hold a bit over 100 Amp-hours, meaning that if the were
totally dead it would take over 50 hours for your 2 Amp charger to get
one close to full. The last 10% could take some hours more. However,
they should have be delivered with at least a 50% charge - otherwise
you'd have a case to return them as DOA, since taking them below 50%
diminishes the lifetime. Look for a manufacturing code to make sure it
hasn't sat on the dealer's shelf for 6 months or more.

That said, I would expect the batteries to need a significant initial
charge (unless the dealer claimed they were fully charged) so the 2 Amp
mode really will take overnight or more to get it up to full. Or you
could use the 10 Amp mode to do it faster. BTW, I regularly charge at a
rate double that (scaled for my larger bank) but my charger is well
controlled so it doesn't apply too high a Voltage. In fact, the
purpose of a deep cycle battery is to be able to take them down to about
50%, and then recharge them reasonably quickly, and repeat this about
500 times. If you really want to charge at a slow rate, this is the
device to get:
