if the batteries die, will it save the data?

Yes, it saves in memory that doesn't require power to store data. It will hold the 3 locations you mark indefinitely unless you overwrite by marking a new location. Good question!

Probably but only over a long period of time and it will only maintain a charge, not charge the batteries up from dead or low.

it has no saving option. If you write something on it will be their until the battery dies or you hit erase button.

If it is totally dead it may not work. For dead batteries a manual charger works better.

Yes. Just keep it plugged in 24/7 and you wont have to worry about the battery going dead or having to reconnect it.

As far as I can tell, there is no way to back up data as there is no output to any storage device. But....it does have flash memory so that you don't lose data during battery replacement.

It does take batteries in the event of power loss but I don't believe it will be functional once the batteries die

I don't know if it remembers if you remove the disk, but as long as the disk is in it remembers where it was when it shuts off. This works even if the batteries die.

I would not recommend it. The batteries are backup if there is elect service interruption.

The new Drobo claims it has a battery backup that will allow it to save any unwritten data to the drives should power go out suddenly. Nothing states it will turn itself back on, and I doubt it will. Still, the new Drobo units are very unreliable and they have poor tech support.

I believe it does with analog phones, but it does lose memory if it gets disconnected. That is why I went towards the FotoDialer, which keeps the memory in place even if the power goes.

No. It will slowly drain the battery. I have several of these, and store them disconnected.

It can be depending on how you use it. Personally, when I'm done using it I remove the batteries and put the device and the batteries in a little sack. But if you tend to use a setting where you want to keep the values you set, then you'll want to keep the batteries in and make sure you have extra batteries with you in case they die (each time you replace the batteries, you'll have to reset the values).

Yes, it will remember the last setting used, even if you do not save it. When you turn the unit back on it will be at the last setting used.

No problem, the device is made made to do time lapses over long period of time. When not in use, it's not good to leave batteries on any device for to long, especially when it's on.

Now that is a good question. If the unit has a keep alive capacitor or battery, it probably does hold the data. I would test it myself, except two straight devices failed to maintain the Bluetooth connection indefinitely; the connection would fail after anywhere from two minutes to ten hours. On a boat, this does not work. I sent both back. Good luck. R.

It depends on where the OBD connection is in the particular car whether the actual GPS device can be seen. You'll have to check your specific situation. No, it dies not drain the battery at all.
