Question 1

Is the F-2AC AC Adapter a recharger for the lithium battery or solely for AC use?  Or, how is the battery recharged?

Accepted Answer

Either the AC adaptor or any USB cable will charge the battery while in the camera.  I routinely leave my TG-830 on the USB cable after importing images to recharge the battery in the camera and never (generally) have to swap batteries.
Even your laptop or desktop computer USB port will provide enough current to charge the battery in the camera (in my experience).

Question 2

How old is this model?

Accepted Answer

I bought the camera in October 2013 when the camera first came out. It has taken awesome HD pictures and video of my vacation to Austrila. It also has GPS and places the location on each picture.
