BEWARE WHEN CHARGING BATTERIES!
This morning we have a 33' Sea Ray in the shop and we had to run the anchor up and open the engine hatch and the batteries were dead. So I hooked a charger up to one battery for a hour, then I went to hook the charger up to another battery.
When I did I noticed a faint smell of sulfer, the smell when a battery charges, a battery emits gasses when they charge and Im sure some of you have smelled this smell before. I had the charger on trickle charge and everything seemed fine, before I went to get off the boat I wanted to make sure the charger was making contact with the terminals so I went to wiggle the negative clamp to insure it was making contact because the post was partially underneath a portion of the deck.
All I remember then is a flash of fire and smoke and acid coming in my face. The ******* thing blew up right in my face and on my hand.
Reason was the faintest spark ignited the hydrogen fumes that the battery emits when it charges, and a little spark is all it takes! Thankfully I didnt get any in my eyes, at least I dont think I did, and just had acid all over my face and hand.
Be very cautious this time of year, I know alot of us dont drive our cars over the winter and charge our batteries when we need to start them so be carefull.

Damn!! Glad you are OK Just another little warning for winter time. If you are going to charge a dead battery in winter, pull the vent caps off and make sure the water did not freeze. A frozen battery will explode when charged becouse the expanded frozen water will short out the plates inside!!

i hope you are ok rob. yes batteries emit gasses when they are charged, the best thing to do is charge it in a well ventilated area, even so you run a risk. i personally hate batteries and try to stay as far away as i can.
