    Battery drain from GPS?

    Without thinking I hooked up the power for my new bluetooth Rikaline GPS to a non-switched 12v line. (It's in the sun roof, spliced into the dome light power.) Until I decide what I'm going to do to fix this (because now it's always on), I'm just going to leave it there. I wonder though how long it will take to drain my car's battery. I'm sure there are some people here who know how to figure this out. Here are the specs of the rechargeable battery it comes with but I'm not using. I guess the GPS is 3.7v/1000mA.

    It won't be drawing from the 12v line the whole time, only when the battery goes dead. When I've charged my Holux, it stays on for about 10 hours, and is charged in about 2 to 3 hours.

    I remember reading about someone else's experiences with this. I'd be interested as well--I'm getting ready to do the same thing!

    Somehow I doubt it's smart enough to work in a cycle of charge/drain. Were that the case though, I could just leave it that way. Although, I'm not thrilled about having blue, red, and green LEDs visible through my sun roof when the car is parked somewhere.

    A battery charger typically cycles on and off, or at least into a low drain trickle mode. Many devices with rechargeable batteries have the regulation and sensing circuitry in them to sense when the battery is low and needs to be charged. That's how my Holux works anyway.

    Try it and see.

    it wouldn't pull more than a couple hundred milliamps, at wivh your battery would last about 120 hours, or 5 days
