I have an 05 Tundra. The battery seems to be shot after numerous times of complete discharge, 9.34 volts or lower. With a good battery installed I hooked up a 10 amp digital current meter in series the postive cable and the battery. With the car sitting, doors locked, the drain on the battery is .045 amps. Is that excessive? What is the acceptable drain on a Toyota truck sitting in the garage? My truck sat 4 to 5 days a week, and would seldomly start after sitting five days. Anyone that would take a reading of your battery drain and let me know I'd greatly appreciated it.
