Battery life? Winter storage?
Looking for some words of wisdom from the Sailnet gurus!
The boat is on the hard for the winter (MD), and I have a few battery questions. We have an Endeavour 33 which we took possession of in June of 2007. Three new batteries were put on at that time (came from West Marine, "maint free"). They have worked well. For the winter I was told I could leave them aboard, and just detach the neg. What does that accomplish?
Also, how many years does the average marine battery last? I am wondering if I need to replace them in the near future.
For your info, the winter of 07-08 I left the boat in the slip and the shore power connected (kkep the batteries charged, etc.)
Thanks for the help, Saltypat
