Hi - First time owner, but sober for 6 moths;-)
I have read everything I can find on battery charging and maintenance for marine AGM batteries and am more confused than when I started.
When I purchased the boat last summer I had the yard add new batteries, they opted for West Marine AGM Group 27, including: House - 198AH@20hrs; Engine - 105AH@20hrs; Bow Thruster - 92AH@20hrs. I picked up the boat in Deltaville and sailed her to home port in Boston. On the way the alternator failed and we installed new Hitachi 80 AMP in Newport. All seemed well until late summer. We have her on a mooring and at some point it didn't matter how long we ran the diesel to charge the batts they would not seem to top off and the engine bat ("Deep Cycle" AGM) began to fail. I removed the batts and they are in my basement for the winter.
1) What should I do to ensure the most effective/efficient charging of the batts while mooring?
2) What is proper care in winter?
3) Do I have the right battery set up for a 2009 Beneteau 43?
Thanks for any info.
