While your battery is venting as you described, you should be very careful around it!!! The gas vapor spewing out is extreamly flammable and a spark could blow up the battery!! Been there, Done that!

Don't trust the gauge in the dash, check it out with a meter.
I have nothing to add to this.I had the same issue and went to an internal regulator type alternator which took care of whichever part was failed.
