Re: [Amel Yacht Owners] Battery Compartment Explosion

James Wendell <ms42phantom54@...>

Thanks everyone for the support and suggestions. We are cleaning things up and it may not be as bad as I originally thought. Somehow one or two of the batteries failed and caused the explosion. I guess my lessons learned is to suspect batteries when they get close to the end of life. I did not know that.

Dear Jamie,
                  I had thermal runaway on a set of Vetus wet cell batteries that were eighteen months old.
The incident happened at the top of the Sea of Cortez under sail, there was no explosion, I was alerted to it by the smell.
The battery box was hot to touch and I was terrified to open it. The inside was covered in battery acid, all the cables were destroyed, four batteries were cracked, eight batteries had buckled cases.
Four were serviceable which I hooked together to allow me to return to Mazatlan for repairs.
It was a harrowing experience as the temperatures of each battery kept rising for hours as they sat overnight on a dock.
I have met a number of people with variations of the same theme.
Good luck with your new engine.
