Battery "Explosion" Hi Everyone, My knowledge base is very limited when it come to electrical. I'm dealing with a simple charging system that has had problems. We have a system ran by 2 x 12V 5Ah sealed lead acid batteries in series. They are to be charged with a Schumacher CR2. Of about ten units so far produced there has been two which the batteries have "exploded" (see attached). Many of the sources I've looked through mention that the battery may be overcharged, but isn't that what the CR2 would be designed to prevent? I've been in contact with the battery company (interstate) and trying to get in contact with Schumacher. I'm confident that with the knowledge base on this forum that someone unbiased would be able to point me in the right direction. Thank you!
