Non-stop battery charging
 

Still finding surprises on a used boat.

It has a Freedom 25 Charger/Inverter, controlled by a Link 2000.

When I turn off the charger using the button on the Link, the charger
only stays off for a few minutes. When the fully charged battery drops
to about 13.6v, the charger switches back on. It's subtle, because the
"charge", "accept" and "float" lights and the "charge" light do not
light. If you're not watching the voltmeter, you won't notice.

Is this the way it's supposed to work? The manuals imply that this is
the default option that can be overridden by DIP switches on a manual
control panel that I think the Link replaced.

The only way I can shut down the charging is to kill the 110 to the
Heart. Unfortunately there is no separate breaker on that line.

Dick,
First thing to do from a safety standpoint is to install an AC circuit
breaker between your shore power input and the inverter.
Second. Have you checked the "charged voltage" setting on the Link 2000
panel? It should be set to 13.5 V (default value). If it is set higher,
the charger might be sensing that the battery is not completely charged
and try to continuously start the charge cycle.
Have you tried setting the Link 2000 to the default settings?
Have you disconnected the phone cable from the inverter and tried to
operate it without the Link 2000?

Dick,

This is not normal behavior. If the CHARGE LED is off after you
press the CHARGE button. it should never enter charge mode
until it is enabled again. Suggest you contact Xantrex.

There is one. It's a 220v boat with a 110 stepdown transformer. The
breaker is before the transformer (I assume, but I better check that.)
The 110 from the transformer goes only to the Heart which distributes
110 to various outlets aound the boat. I can't kil the 110 to the
Heart without killing the shore power to the outlets and I want to
keep it on to run an icemaker/freezer/

I don't see how to read or set the "charged voltage." BTW, these are
gels. The charging works fine, goes to the third stage and stays there
while I do minor current draw. It does this whether the charger is
ostensibly on or off, though.

Have you tried setting the Link 2000 to the default settings?

I was considering a hard reset but wanted to check first whether this
situation was normal. I have a question in to Heart but no answer
yet.

The only control on the inverter/charger is an on and off switch. The
manual has reference to a simpler remote panel with dip switches on
the back, but if there is one of these wired in, it's well hidden. I
believe the Link replaces the standard remote panel.

The Heart manual says:
Dip switch 4: On= Disable, charger responds to on-off switch; Off =
Enable,: Charger on when AC is connected (default). The charger is
acting like Dip switch 4 is on, in the default position. Hmm, I wonder
if there are dip switches on the back of the Link control panel.
Another thing to ceck

Dick,
Yours must be an older unit. I don't have dip switches on the inverter
or Link 2000. There are two buttons and 4 LEDs on the inverter front
panel. One button turns the inverter on/off, the other button turns the
charger on/off. LEDs indicate status.

Dick, are the batteries hot or percolating away the electrolyte?

I just installed 700AH of tall golf cart batteries in Lionheart. The
pulse-type automatic cutoff charger has been running full bore for 2
weeks under the load. It would take 70A for 14 hours to charge them
discharged, but this charger is only a tiny 10A "trickle charger" and
we keep turning the lights, radios, etc., on it. I doubt it will ever
switch off. The solar panel adds about 5A for 8 hours on a sunny day
but that's still not much charging power to these monsters.

At 10A there's no gassing at all. I think I heard one of the 6V
beasts laughing at the Guest charger...(c;

If it's not using much water, the battery isn't "hot" (warm is
normal), and there's not a lot of gassing going on.....stop worrying
about it and let it get on with its job.....

3600 planes with transponders are burning 8-10 million
gallons of kerosene per hour over the USA. R-12 car air
conditioners are responsible for the ozone hole, right?

They are gels, so probably won't outgas. I'll check temp. Somehow,
though, I think a charger that is on without any indicator lights
saying so is going to bite me on the butt sometime.

You haven't mentioned how you know the charger is running - are you seeing a Voltage or a
current flow? Its possible that you're getting a faulty reading from the Link indicating
a small current flow. You might try putting an Ammeter in series with the battery
connection to verify the flow.

FTIW, my Heart charger is "on" 24/7 most of the time - I don't recall every turning it
off. Since my fridge is DC I rely on the charger to keep it running, and as longs as it
doesn't over/under charge the batteries I don't see the problem.

ANSWER:
When the link 2000 is connected to the Freedom 25 all control over the
invertor is through the link. Refer to the link manual to set the many
functions of the invertor/charger. There are more than 15 functions
that can be set from the link if you want to monitor and protect your
investment. If your link does not have the advanced battery
temperature function set the charge voltage range based on the average
battery box temperature. Once the functions are set the charger can
be left on to maintain the batteries at full charge and unlike most
other chargers the voltage will remain at float state when small loads
are applied. Because this charger can produce over 100 amps I
recommend the power sharing function be set for low output, most boats
can get buy with a 25 amp. charger.

Voltage...on the boat's master voltmeter.

If I turn off the charger when the batteries are fully charged, first
a relay clicks off and amps drop to zero or go slightly negative.
Within 5 minutes, the relay clicks on again and the voltage climbs to
the gel's accept voltage of 14.4. Amps go up to 5-10 also. After a
while, amps drop off to a mild trickle (.1-.4) and the voltage drops
to 13.6. The relay never clicks off. The indicator lights never go on.

I'm going to do a hard reset next time I'm on the boat, since nobody
said "Hey mine does that too."

My refrig is AC, and there should be no DC running except for an
occasional bilge pump.
