Depends on how many watts your TV works at and the capacity your battery is rated at. Once you have the TV watt rating then you can calculate how much current the TV draws whilst operating by: WattTV / 240V OR 120V (depending on your mains supply – what country) = Itv Where “WattTV” is your TV’s watt rating and “Itv” is how much current you TV draws. Then to work out how long it lasts: Itv / BattI = Hours Where “Itv” is how much current your TV draws and “BattI” is the current capacity your battery is rated at. I’m pretty sure this works.
