Re: cooking batteries

boatyard to run the generator & charge the batteries every 2-4 weeks.
They clearly did not do this and they also left the battery switches
on, causing the batteries to be "dead" when I arrived in May 05.
Upon charging using shore power the result was exactly as you
describe. Sizzling heat, strong smell and water (acid) on floor of
compartment. I got by temporarily by disconnecting the two worst
batteries (7&8 from memory) and charging while motoring was OK but
problem re-occurred with shore power. All the batteries had to be
replaced and this cured the problem. The batteries (original Delphi)
were by this time 4years old & therefore towards the end of their life
I realise you say that your batteries check out OK but the symptoms
