What happens to my current track if I lose battery power?

[AboveTreeline]

I have a Garmin GPSMAP 64s handheld device. If I am recording my tracks and lose battery life causing the device to turn off, what happens to my tracks?

Then if I replace the batteries and turn the device back on, will it pick up recording automatically? How does that work?

Thanks.

The Track points are stored in real time, so Tracks recorded before 'turn off' will be retained, the unit will automatically start recording a new track when powered back on
