I was looking at GPS Trackers such as Spark Nano 4.0. I wanted to apply one of these devices inside my boat to exclusively use it for motion detection in case of theft.

The battery life of this device is of 2 weeks, for accurate tracking in movement. But I can't find how long it last for the motion detection task.

I'm planning to deactivate it then, when I'm sailing to save the battery.

Why would you want exact motion detection when sailing? – HTDutchy Apr 28 '14 at 6:29
@HTDutchy For when my boat is on the dock – Patrick Apr 28 '14 at 7:53


Reading up on the device and from simple knowledge.
I'd say device life would largely depend on the update frequency.
The device will always easily acquire a GPS fix with an accuracy of at least 5-10 meters.

I couldn't find the default interval to quickly but I assume that you can easily get more then 2 weeks when updating every 2 hours or so. (should be enough unless you're dealing with a racing cat)
