What about leaving the charger on overnight?

I don't know. I guess you could try it and see what happens.

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.

Sounds about right.

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

Sounds about right.

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.

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.

Harbor Freight has a new load tester, now. 0-500 amps! I gave my 50A
fixed load tester to a boater who is nice to me and got the new one. It's
a beautiful unit for so little money.

If a man goes way out into the woods all alone and says something,
is it still wrong, even though no woman hears him?

2A x 8 Hours = 16AH. Charging isn't very efficient, so you'd be lucky to
get 10AH of real charge this way. Overnight won't hurt them, even if the
charger were locked on. Don't leave them a week without monitoring until
you figure out what's what.

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


This can't be the 'Tuuk' who caused all the trouble in rec.boats a few years
ago??
You almost sound sensible!

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:

THanks

Yes, that little charger tender plus is a pretty practical little device.

I been reading a lot and bubbling (to a degree) is common and expected.

Thanks for all the good advice.

You would have a hard time seriously overcharging a 100 amp hour
flooded deep cycle battery using a 2 amp trickle charger.

Being a new battery, it probably has never been fully and properly
charged. Battery charging is more complicated than merely stuffing
electricity back into the battery. The last 5-10% of capacity is the
hardest to achieve.

Seems that getting batteries with 5-10% more capacity than you need,
and not worrying about the last 5-10% would be a solution.
I suspect that is too easy, aside from psychology, and somebody will
explain why.
I do know that I always find something in the last place I look for it

Batteries are never quite big enough. I think there is a tendency to
add things that draw power., or simply get more casual about useage,
as your battery banks and charging system expand.

I changed over to AGM batteries for a number of reasons, but one was
lower internal resistance, which makes for faster and easier charging.
That effectively increased my capacity without adding any weight.
