Charlie and all, The same thing happened to me with a Battery Tender brand maintainer which is a little more sofisticated than a trickle charger. The battery was a Sears Die-Hard maintenance free battery and after several days I went into the garage and found plastic pieces all over. It must have been a real bang and glad I wasn't near it. I checked my invoice for the battery and it was 10 years old (surprise) and was working fine for about 9 1/2 years !! Time flies. Since then, I don't really like the maintenance free sealed batteries as this may have been prevented if one could check the fluid levels in the cells. I have had only one problem with Antique Automobile Battery Company batteries and that was a new one that just would not take a charge when new. They exchanged it , no questions. All of the other 5 batteries I have of theirs are fine, some lasting 6 years and still starting. I think we should not trash Antique Automobile Battery with blanket statements that they have "tons of problems" when they may be no better or worse than others. Some of the problems are created by our car electronics and no fault of the battery, per se. I've no vested interest in AAB; just trying to put everything in perspective. One thing I learned at a "battery seminar" and will pass it on is that when connecting anything to the terminals, blow some air across the battery top before connecting as explosive gases will lie there and if, when connecting, there is a spark, kaboom potential. (Can't hurt!) Yes, I have gained new respect for those little black boxes. (Well, most of them are black!)

About 2 or 3 days later I went into the garage and the battery was destroyed, as it had exploded.
