An update on this. Monday morning I brought my batteries home (I've got two of
these:

dated May/June 2014 with relatively light use and constantly maintained by a
3amp solar charger). And I bought this inexpensive
On a related note- I have been wondering how to test that my alternator is
correctly regulating charging. I am presuming the test is to measure the
voltage at the battery with the engine running. What should you measure for
voltage for a fully charged vs. partially discharged battery?
Also,
While you're at it clean and protect the ground stud and ring terminals on the
back of the starter. Mine had oxidized and created issues.
You're in there anyway, and have more room to work at the moment.

Battery voltage with the engine on should be 13.8 volts or higher.

Shouldn’t the voltage vary depending on the state of charge of the battery? I
thought that is what the internal regulator was supposed to do to prevent
overcharging. Dave

Charging voltage should be 2 volts battery voltage. The way I was thought was
check battery voltage with batteries at rest (no draw or charging) then start
engine and battery voltage should show 2 volts above previous reading. If it is
higher you have a bad regulator lower most likely a bad alte
If you have a simple fixed point regulator, it always wants to be at the
setpoint, which normally is somewhere between 13.8 and maybe 14.4 volts. If the
battery is real low or you have a lot of loads on, the voltage might not make
it up that high.

I'm sorry to be the bearer of bad news, but if those voltages of 4.7
volts and 5.7 volts were correct, they mean these batteries have been
quite severely damaged and will never have anywhere near full capacity
again. That is not a maybe. You can get many batteries like that to take
a surface c
I can tell you from personal experience that AGMs won't servive either. I
had 4 hooked in parallel that I flattened to 4.5 v . A painful
experience. At the same time I lost my inverter charger.

Well, if I learned an expensive lesson, I'll just have to accept that. I
checked all the cells before putting the charger on them, and they were full.
After charging they are still full (even though I heard the liquid bubbling
i.e. creating and venting gas toward the end of the charging period).
My Landfall has the Yanmar 3QM30...on the odd time the ignition goes dead it's because of a dirty fuse connection...there is a single glass fuse on the side of the engine. Sometimes it's the wire connectors to the fuse...they get dirty.
