Battery alarm while moored.
2008 Beneteau 37'
Two batteries - Cranking and deep cycle
Battery age - <1 year
While on a ball recently our low voltage alarm went off in the middle of the night at 10.8V
All systems were off - main breaker was off - fridge was off - nothing was on. Started engine to charge for 30 minutes - All good
Three hours later.....same thing.
Ground problem ?
Suggestions on a troubleshooting starting point ?
