Battery Overcharging
So I had my S5 for 4 months now and everything was fine until about 2 weeks ago when the voltage meter in the dash is reading 16v!!! If I turn the car off and pop the hood then I can hear the battery hissing. When I bought the car I noticed a brand new Bosh alternator and im not sure how old the battery is. What are my options?

nope, not a battery (but the battery is probably now burnt up), you have a bad alternator.
The regulator inside the alt has failed.
Anytime a alternator exceeds 15 volts it will cause damage to the car. Driving the car with 16 volts will pretty much start burning out the computers and lights.

probably not remanufactured (all wear parts replaced) but rather rebuilt (all broken parts replaced).
It is very common for cheapo alts from a zone type auto parts store to be rebuilt and often fail soon after installation.

ya, icemark is right, a overcharge on a battery is one of two things, bad regulator, or bad cell. Just because its new or reman doesn't mean it wont got bad, luck of the draw. but thats why there are warranties.
