I never, ever open a camera housing on a boat. It's very bad luck.
If you want to maintain a dry housing, keep it in an AC dehumidified room when changing batteries. Keep a small bag of silica gel in the housing when using, and use the vacuum system if you have. The vacuum does not need to be excessive either, just enough to give the o-rings a squeeze.
The OP as pointed out, is taking way too many shots. 300 shots in one dive? Hard to have any time to enjoy the environment. Better to frame, compose, focus and shoot far fewer frames per dive. Also, power the camera off when not shooting.
I can usually get through a 3 tank day on one battery, and if I run out of juice, I don't sweat it.
