  • A Newbie Question

    While I have no problem with the 'puter aspect of this sort of thing i'm completely clueless as far as cars go.

    I tried using the search to find an answer and some googling, but nothing came up that was exactly what I was looking for.

    Basically, I've heard (and read here)that leaving the cd player running, or even a carputer while the engine is off will drain the battery.

    My question is, why? Obviously batteries drain when being used, duh, but why isn't it a problem when the engine is running.

    Also, how long will it take for a typical carputer to drain the battery running at ~60w load in the above scenario.

    One more quick question...from reading this board an engine crank is the pc rebooting when the engine gets turned on (and/or off?). From reading the description of the M1-ATX PSU, I'm gathering that there's a circuit in there that prevents this from happening, correct?

    As you can see I know nothing about cars. Doh!

    Thanks in advance for any help, it's appreciated.

    Cars have alternators that work when the engine is running to recharge the battery.
    Spent so far: $1,755

      Makes sense. I figured it was something like that.

      It's not really that big a problem for me since from experience, a normal stock cd stereo can run for quite a while before the battery dies, but i'm afraid a carputer will drain it much faster.

      I wouldn't be able to justify spending 500$+ on this if I wouldn't be able to sit in the car when idle and listen to some music for 20-30 mins if I wanted to.

          I've run mine for an hour or more with the engine off. You can do 25 minutes if you don't have a giant power sucking PC.

          By the way, if you're battery is in poor condition, this won't apply!

            Ah okay, It's a lot better than I thought then. I'm planning to run an Epia M1000, so it won't be consuming much power.

            Thanks a lot for all your help!

              That's what I've got. You should do just fine with it.

              Edit: if you use a Carnetix or Opus, they'll shut you down when voltage gets low and you ought to still be able to start the car.

                I'm pretty sure the M1-ATX does that too, right? I'm on a budget and the Opus is a bit pricy

                  Sounds like it does. I'm not too familiar with them but I read the description and it seems to fit the bill.
                  I'm not certain how good a regulator it is, although it can take a variety of voltage, so it probably would work. Others would have to weigh in on whether an additional regulator is needed or not.
