A couple days ago our Link 1000 monitor indicated that the bulk charge mode
was not switching over to acceptance, that our batteries were not holding
their charge (went from 12.9 to 11.9 overnight with no load), and the
batteries were steaming. We disconnected the batteries to let them cool
down.

We have two 8D 12 volt batteries attached to the inverter/charger.

We have looked at the manuals to see how to adjust the bulk stage thinking
that maybe that is the problem, but no luck in finding any reference. We
have not reconnected the batteries to see if things will reset and the
batteries can come back to life.

We do have a quote to replace Freedom 10 with a Magnum 2012

Would anyone have some guidance for us?

It appears that the batteries are in distress. I would expect that you
have flooded cells, and you don't indicate the age of the batteries.
Check to see that they are watered above the plates, if any plates are
exposed, it's likely the batteries are toast. Before adding water, check
the specific gravity of each cell, and check the open circuit (no load)
voltage on each battery. If any single cell shows a SG lower than the
rated SG at a given voltage (there are tables to refer to- Check
Trojan's website for more info), it's likely the battery is defective.
The fact that your charger is holding on bulk indicates the voltage is
not increasing. The likelihood of an internal short further exacerbates
that condition and will cause the battery to heat. If one of the set is
defective, it's not recommended to replace one, as the remaining old
battery will soon follow, as the resistance imbalance between an old and
new battery will prevent proper charging.

It may be that one of the batteries has a shorted cell - that would
prevent the pack from reaching full charge. If you check fluid levels
in all the cells, you'll likely find that all but one cell in one
battery requires water, and the remaining one, and the cells in the
other battery, do not require water - the shorted cell won't require
water, but will cause the rest of the cells in that battery to be
over-charged.

I agree with Steve and Peter that your problem is more likely bad batteries than a bad inv/charger. For testing, you might borrow a 12v battery, even one from a car. Replace the 8D's with the borrowed battery and try charging. If things now work normally, replace the two 8-D's with 4 golf-cart batteries and you're good to go.

I should have suggested, before lugging another battery to the boat,
separate the existing batteries, and try charging each one separately.
If there is a shorted cell in one, the other should charge normally when
tried on its own.

I've had a few cases where one battery of a pair died. One case had a
shorted cell, with symptoms very similar to your case. In the others,
one battery had very low capacity, but the fault was masked by the good
battery.

The batteries in question were replaced 3-4 years ago. They have always
tended to overflow and needed to be wiped fairly regularly. They have not
been overfilled. We will have to get someone to check this out for us. We
just don't have the expertise. Thanks to everyone for commenting both on
the list and privately.
