I have a 2001 Toyota Prius with an intermittent issue with the 12 volt battery. When not utilized for one day I obtain the 12 volt battery reduced and requiring a jump to start the car. The car then works usually for perhaps a few days, before the trouble repeats. The 12 volt battery power has been tested and found to be OK etc. Apparently, on an intermittent basis, there is a slowly draw on the 12 volt battery. Any advised guide with this problem would be greatly appreciated and thanks !
