It depends. I wouldn't drive around with it charging all the time. But, if you're just charging your battery on camping trips and then you use a battery charger to maintain the battery at home you should be fine. At least mine has been and the truck runs 14.3 volts with a 120A alternator. I haven't had any problems with overcharging the battery. Also, I try and check and add water as required to the battery ever month. One thing to check is the output of the alternator on your TV. If its only a 40A or so you might burn it out charging a battery. The alternator in most cars is sized only for the car (and barely that).
