Re: [Amel Yacht Owners] Battery Compartment Explosion

I think Bill has some good advice there. After my experience I will test periodically. Plus I have a Maretron temperature module on my N2K system with a spare thermocouple input, and I am going to monitor the temperature of the battery compartment itself. Some have suggested that the fact that I am on the hard could have bumped up the temp. I believe that. My solar controller does monitor but only on the negative terminal. Who knows if it was reading correctly.
On another note, I just got my first estimate to fix all the damaged woodwork. All I can say is ouch. The electrical repairs should be pretty simple but I suspect quite expensive. Still waiting for insurance approval to start repairs.

If you load-test (current CCA) and test for internal shorts before a passage, you should not worry about a major failure as you had. I have been testing batteries about every 3 months for at least 6 years. They fail one at a time. I did have the crappy Varta batteries fail one after another totaling 6 in two months before I could replace them. All you have to do is rearrange and disconnect the failing batteries from the bank in pairs. They are wired in series in pairs to the bank terminals. What this will cause you to do is charge more often. And if you want your battery monitor to report the correct state of remaining power, you have to change the total amps which is programmed into that monitor.
The only thing(s) that you need to do is monitor for too many amps going into the battery bank for too long (using your battery monitor), or monitor for battery compartment temperature...or both. I do both. I installed a simple two zone digital temperature device with an alarm. I think it cost me $15 in eBay. If I was doing it over, I might buy a better one, but this cheap China made device has worked flawlessly for at least three years.
After a little time you will love the simple genius of the Amel SM2k and 54 battery bank design.
