Most batteries I have seen are a 5x or 10x less than that.
Will, Renewable Energy batteries are built much heavier with thicker plates than less expensive Auto Zone deep cycle batteries. They often have different minerals mixed in the lead, non conductive matts between to plates to resist shorting if the plates ever warp from heat, and deeper bottom sump areas to keep flaked off lead deposits from shorting the bottom of the plates. This makes them much more durable in long term deep cycling applications but makes them cost much more.

There is a big difference between someone who has a few solar panels and batteries and occasionally runs a toaster oven off them and someone who works those batteries every night running lights, tvs, hair dryers, and water pumps even after 2 days of rain so they don't get fully recharged.
