    I think that some house alarm backup batteries are 12V.
    Not sure what you are really planning - I have solar panels on my caravan, going to a regulator, then 12V leisure batteries, and on to an inverter.
    A 12V adapter for the laptop would be more efficient than an inverter. You really don't get that much power from the smaller solar panels.

    Maplin there on Jervis St. sell batteries of various sizes. Considering you're using an inverter you'll require a significant amount of current from the battery in which case a car battery would probably be the way to go. As JamesM says though, you'll more than likely require some method of charging other than just a solar panel on its own...

    I'd steer clear of car batteries, what you need is a deep cycle battery like a leisure battery used on campervans and boats or a forklift battery( from electric forklifts.

    Yes, a deep-cycle battery is what you need. This allows you to run it nearly flat without affecting the storage cells. SLAB's suffer from constant charge-recharge cycles and fail prematurely.
