This is probably a difficult question to answer categorically but I’d appreciate any thoughts.
Our small boat’s battery has been too flat to start the engine a few times lately (after 2-3 weeks inactivity, no shore power) and I’m wondering if the battery is just knackered or whether there’s some kind of drain going on.
The boat’s kept in a dry stack and the battery is isolated when not in use. Voltage across the battery is 12.2v today with no use over the last couple of weeks.
I’m inclined to just buy a new battery but before I do, is there anything else I can realistically check? I did have a look today to see if I could get a multimeter across the isolator but the way it’s installed meant this wasn’t possible easily.
