Depends on which one you get. From their website, the lowest capacity is 50 amp-hours, the highest is 75.

Your TV is a 60W/12V=5 amp-hour load.

You should only use 1/2 the amp-hr capacity of the battery so you can run it between 5 to 7.5 hours.

Optimas may be great batteries but they sure don't have as much capacity as an equivalent size wet cell battery. A group 27 typically has around 120 amp-hours capacity. (so your TV could run for 12 hours).
