Q: can it charge a dead battery and if so how long would it take?

It can. The charging time depends on the capacity of your battery.

Q: is this charger temperature compensated, i.e. charges at/to higher voltage in colder temps?

Yes, it ramps the voltage up and down based on the temperature. For example, I live in northern Minnesota. I have a parasitic drain on my battery, but it's been in the -20 to -30 degree below zero Fahrenheit range for the last couple of weeks overnight. That would compound my existing parasitic loss, and this charger has been adjusting the voltage to compensate and keep my battery topped off. I will track down my parasitic loss this spring, but I put this charger on my car every night when I get home, and it's topped off and ready for the day every morning. No issues starting even at -25 degrees. The display rotates between the voltage and the temp as it charges.

Q: I have two 12 volt Marine deep cycle batteries turned into a 24 volt system in my boat will this charge both of them or do I need to separate them

The description says it will do it, so I’m gonna go with that, you shouldn’t have to separate them.
