We were on our way out for dinner when we thought we heard a gunshot, saw smoke near the front of the coach and then smelled the distinctive smell of sulphur/gunpowder. It was a pretty scary couple of minutes trying to assess whether that could actually be true.
Well, after a few pensive minutes of investigation we found that one of the batteries (now 40 months old) had exploded in its case. How lucky we were to have been nearby to hear it rather than to not know and not be able to address the splattering of acid in the compartment. We are also thankful that the containment system worked as well as it did and prevented damage to surrounding componenets.
We're 3+ years full time now and say on shore power. I've been pretty faithful in topping the batteries (they have needed very little maintenance) and this really surprised me.
So, I have a couple of questions;
Is it indeed smarter to disconnect/isolate the batteries when connected to shore power (could there be any long-term consequesnces to the converter if it has no battery/capacitance to smooth things out?
Has anyone had something like this? We had good venting (I thought) and when I checked it there was no blockage. I'm wondering in a purge fan is in order.
