Thanks for the advice to each of you.
In Iowa we have to crane our boats out of the water the
3rd week of October. By December the water is rock hard. <G>
Its why Sue and I are more determined each winter to leave the
north. You never hear of folks who worked their whole life in
the South, moving to the north!
We have a large charging system for use at the Docks, but there
is no electricity on the storage lot we crane the boats onto.
Without any electricity for our normal charging system I
had to find a way to supplement it during winters. I try to
carry my EU2000 Honda generator to the lake and use it
about 10 hours each month when I am back in Iowa.
The Honda puts out a continuous 14 amps at 110,
but I worried it might not be large enough to properly
run the 110 volt house charging system.
Since I was leery about rewiring the boat's shore power plug
to the small generator, as I do not have my original documentation,
and worried it might not have enough output, I have used
a small the DC charge directly to the battery bank via cables.
Thanks to each of you for your help.

Over the winter I occasionally use an additional charger
to keep the charge up. <snip>

With all due respect to Andina, yes it does matter.
As to how much it matters, that depends on the size of the batteries,
charging
current and ambient temperature.
When you say additional charger - what is it additional to?
What is wrong with the original charging source that you feel the need
to
supplement it?
What you have always done is the correct way and has been proven as
such by
numerous industrial users who maintain standby power for utility and
communications system use.
If you are talking about a pair of Group 27 batteries then yes it
probably
doesn't matter since the cost of replacing the batteries after a few
years is
less than doing the job right.
However if you spend $1000 or more for a battery bank then you should
be able
to expect 10 years service and then the correct design and procedure is
significant.
