In the past few weeks the remote control for my Tivo Premier has not responded immediately at first try in the morning. Obviously I thought to change the batteries. But before I did that I checked the voltage with my multimeter and both 1.5V AA batteries indicated 1V each. So 1V batteries barely work and the light on the top of the remote is dim. From what I've glanced at on battery life, 1.3V and up is the best voltage.
