Hello,

I have an RTC running on a big 12v battery. Although I just tried using two 1.5v 357 type lithium batteries. I thought these would power my DS1337 for over a year. but after less then a day I had only 1.1v left in my batteries... Is there a way to 'hook up' the battery ? I grounded the batteries together but I use a diode on the positive to the RTC because I do not want these batteries to get a 5v charge from the LM 7805 when the main circuit gets turned on.
