If I do not turn it off, how quickly will it drain a fully charged battery in a car that is parked?

Garry - i'm not 100% positive (like 75%), but pretty sure that the OBDII comm shuts down shortly after most cars are turned off & I believe that this device (powered by OBDii) will also shut-off and thus not drain the battery.

I have experienced no battery drain issues. I almost always turn it off when not in use as a precautionary measure. It has been on no longer than 24 to 48 hours without cranking a vehicle. Like I said earlier , I have never had any issues. It seems to use minimal power.

Yes, if you use it with your car turned off. As long as the engine's running your battery won't be drained.

Unless you leave the car parked for weeks at a time this will not be an issue. The draw from this device is very low. You will need to turn the device off then back on to resync with your phone, however. I always just turn mine off when I get out then back on when I get in. Again however no need to worry about your battery.

I don't connect it to constant because it could drain your battery. I rely on the back up battery when the car is off.

It's doesn't have to be on while charging I installed mine with the batteries full charged it read as full had it a while works great keeps me from being towed home lol

Unless it develops a fault, no. My Infiniti takes approximately 11 days to drain the battery to an unusable voltage.

It will stay on parking mode until the vehicle starts moving again or until the power supply is shut off (if it gets unplugged from the outlet).

No, It will not drain your battery and just to be on the safe side its better to keep your car running. If your car has an old battery then run the goddam engine. If you are stupid enough not to run it while your battery needs juice .. Just call AAA !!! ERGO use common sense while you use electronic devises that uses electricity. Har har har !!!

No.If your car outlet connect straight to the battery you car record on parking lot,but you gonna kill battery.

You can disconnect if you are going to use the car soon or else keep it plugged in so that the car continues to receive minimal current in order to maintain full charge!

I do not have this charger anymore, but if I recall correctly: it will turn off. However as long as the battery is completely charged it is in my opinion just cosmetic. R.

Only if you leave the device (GPS) connected. As long as you unplug the element you are charging when the bike will be shut off for more than a few minutes, you should be fine. I left my GPS plugged in overnight after a ride and murdered an otherwise good dry cell battery. I think some folks wire in an/off switch to save on plugging/ unplugging routine. Either way, you have to remember to disconnect the charger from the device when the motor is off for any extended period of time or it will drain the battery dry.

The unit gets cold very fast (even freezing). I haven't tested how long it stays cold after I turn it off. I leave it on in the car as the unit only uses energy when it needs it. It doesn't drain the battery like the cheaper ones when you leave it on.

If you turn it off when your not using it you will get a lot of life out of the battery.

I would have it plugged into my truck 12v outlet all day while driving, but I would unplug it in the evening and let it maintain whatever coolness it had. However, I didn't want to run down my truck battery, so I never attempted to leave it plugged in for too long without the truck running. Sorry I can't answer your question.

If you hook this up, with a device connected to it all the time, yes as long as there is power to it all the time, it will drain the battery. The drop in voltage would depend upon what is connected to it and what the draw rate of that item is. When you hook this up to the fuse panel you will need to be on a circuit with a minimum of a 10amp fuse. You will also need to find a circuit that turns off by the ignition switch when the key is removed, or you will need to unplug your device to eliminate the draw of voltage by the device plugged in to this cord.

The only way it turns off is if you unplug it from the cigarette lighter plug. You can change the settings so the screen doesn't stay on for more than a minute when it is first plugged in. I use that time to check the camera views to make sure it is recording where I want it to. It hardly uses any battery power, especially if the screen has timed out as I left mine on for a week trip when I left it in the airport parking lot. Car started right up.
