Most every battery you can purchase in the US is 'mercury-free'. The card of 337's in my battery storage show 0% Hg [mercury].

How many hours of constant use does each battery last?

Battery life depends entirely on current draw. Without knowing your application it’s impossible to say. In a small quartz watch I get from 3 up to 10 years.
