I have 2 Group 27's deep cycle....now 9 years old, and I leave them on
the boat over the winter with everything disconnected. They get a full
charge in the Fall during layup bringing up to 6.2V to 6.4V.....also
check the levels of the electrolyte (acid) and add distilled water if
necessary before charging.
For a few winters, I have left them this way without a charge until
Spring....in the Spring, they read 12.4V to 12.5V. Most winters, I
will visit the boat and give the batteries a charge with a 6V
charger.....maybe an hour on each battery. Never an issue.
There is a permanent 'smart charger' on the boat but our club will not
permit an electrical connection to the boat if it is unattended, good
policy for obvious reasons, but being on a trickle charge all winter has
not been necessary .
