    batteries like that are designed as emergency backup batteries. they would normally have a constant trickle charge keeping them at full capacity at all times until they are needed. in a car they are getting 'fast charged', but probably not for a long enough period of time to make them last all night.

    as nobb mentioned earlier, you would probably be better off with a deep cycle battery. normal lead acid batteries discharge quickly even when the devices draining it only draws low currents. deep cycle batteries can provide a more consistent voltage as the battery discharges, and can provide that voltage for a much longer duration.

    good luck

    and you can always add programs to the 'startup' folder to have them launch automatically when windows boots up


    why would it have to power up, then turn off, then start again? it should just power up and stay on
    When you loose your stanby data due to the m2atx losing power, on the next boot the system will hang. I have just checkd out the hibernate thing and will give that a go, sounds good.
    Im friendly with the start up folder but it will never take you back to the song you last had let alone the play list. It seems ironic that a computer is unable to do what my in dash cd player will :P

    yes, deep cycle batterys are looking like the next alternative i think. Is a normal car battery classed as a deep cycle? It appears to hold charge for longer than these sla's and charges quite quick.

    Well you only have about 28.4Ahr worth of SLAs, which isnt all that much. Thats why your voltage is dropping so fast. Decide on the battery to get by how deep you plan on discharging it regularly. Most deep cycles sold at stores (like for RV, marine) arent really deep cycles at all, they are just modified starter batteries. I would only discharge those to 80% DOD regularly. If you are going to discharge down to say 20% or lower DOD, then I would look at getting a more expensive, real deep cycle. Like the stuff they use in wheelchairs, forklifts, golfcarts.
