Okay! well I tested this out.. I watched all of Old School... then I had the car on for the entire I, Robot movie with my date... during the I, Robot... I only had my cold cathode lights on ... just 4 of them... and my battery lasted NP!!

So... Old School was like... 90 something mins. long... plus then a good 90 mins of cold cathod lighting also....

it lasted awhile

LOL and if you really think I bought a $1200... well its like 2500 for most people ... DVD player! and not have it run all the time... then your wrong lol Mine is made to play ANYTIME I want... not just when the car is parked....
