[Nerazzurri]

I've been playing 2 or 3 weeks now and I've been gradually increasing the realism, the most recent thing being limited fuel.

Now I want to limit the batteries, air and CO2. Thing is there's nothing in the game manual about them and not much in the community manual.

I'm just looking for general tips regarding these - how long each last, things like that. For one thing, if your stationary while submerged are you still draining power? That's just an example. Any tips would be good.
