Will a deep cycle or marine battery work inside of a car or truck in place of a regular vehicle battery? (hybrid, engine)

Hi,
Is it possible to start a car or truck with either a "deep cycle" or even a "marine" battery? Is it advisable to do so, and install it and run the cars entire electrical system off of it also? Or do I have to stick to regular, automotive-only type "cold cranking amp" type batteries ONLY?! (The kind that produce short bursts of high power instead of long, extended periods of medium power like "deep cycle" or "marine" batteries do?).
Thanks
Why would you want a deep-cycle battery unless you intend to run a lot of electronics without the engine running for extended periods of time?
If that's what you intend to do and you actually need a deep-cycle battery, Optima makes an AGM deep-cycle automotive battery, but it does come at a cost of lower cranking amperage.
All Toyota hybrids have deep cycle batteries, but they do not use it for crank.
Look at Hondas, which battery Honda hybrid has.
Their hybrid is different and starter is employed to start the engine.
That's the battery you want to use.

If the Marine batteries produce a certain amount of CCA's its fine. Think about it, a 90 HP Yamaha Outboard is 1.8 liters, 4 cylinders, not at all unlike what you'd find in a Civic or Corolla.
The deep cycle aspect will only be of benefit if you typically run accessories (Like a big stereo) with the engine off. The marine aspect is only useful if you put it in a boat.
So you would be paying more for features you would never use, unless you do intend to use the deep cycle aspect for some reason.

Yes, that's precisely and exactly what I was thinking of doing. Running electronics on the vehicles main battery and use it to also start the vehicle too (as an afterthought ).
Deep cycle batteries tend to be bigger and so may not fit in your vehicle. Also, I believe the CCA rating for a marine battery is at 32*F, whereas for an automotive battery the CCA is rated at 0*F. If you live where it gets cold, a marine battery isn't a good choice for your car. Think about it, most boats are not used in freezing weather.
I think of deep cycle batteries marine being most necessary for powering electric trolling motors, because with one of those you still want significant current output (relative to baseline) to sustain running even when the battery is at 30% charge - a common situation for that system, else you're not getting home. From my limited understanding, for automotive batteries used to start the engine, it's more important for them to be able to generate really high current for a short period of time when the battery is in a high state of charge (the typical need and conditions for that system)... plus an ability to still retain that kind of output down to low temperatures.
