MBA Marine Posted May 19, 2014 Share Posted May 19, 2014 A lesson in life and complacency, Saturday afternoon I go to a boat a the first thing I noticed was that the 24v battery bank was being charged really hard, batteries boiling inside and gassing very heavily, I had turned the chaps charger down low, this charger being a garage style charger with Boost/Starter function. (mistake no.1, off was the correct step to take). My task was to remove the starter motor, I note the battery isolator had previously given up and bypassed with the cables on the same side of the switch, when removing the starter cables to make them safe (hahaha) I must have produced a ickle spark (remember that charger that was still on! Doh!!) , if im honest I cant remember that part to well, but suddenly a bang like a gunshot and part of the battery was gone and I had light battery acid shower (good day to wear shorts and tee shirt). I'm a very very lucky boy as I was leaning over that battery. The pic of my inner elbow and temporary loss of hearing in right ear were the extent of the injuries. But not to be defeated after a good wash I did go back in and remove the starter before going and tending to the arm! The 2nd and 3rd pic's are the batteries I was leaning over. A couple of days on the ear feels like it has a bit off cotton wool in it but im sure this will pass, more importantly I'm alive, in good humor and i'm still pretty. So for them are not aware Hydrogen is very flammable and this the gas that batteries (vented) give off when charging, dont be an idiot (like me) vent the space and turn stuff off before you play! Oh and dont Boil the f**k out of your batteries with charger made for garage use on the high setting for god knows how long! Rant over. From behind the keyboard, many are very quick to point out peoples mistakes, and quicker to use a search engine to give a textbook perfect solution to any problem, I was complacent and was given a wake up call, I'm not afraid to admit that, I replaced the battery today and it took me few moments to tell myself that I wanted to go back in that engine room. Those who knew let this be a reminder, those who did not know let it be a lesson learned. 8 Quote Link to comment Share on other sites More sharing options...
