I have a 99 Rx300 that keeps draining the battery. Ive changed the battery twice and if the car sits for no more than 2 days the battery dies. What could be draining the battery? I read in consumer reports that for this particular model and year, the electrical system was a trouble spot. Any one had this problem with there rx 300?

 

I have the same problem in my Toyota Harrier 1999 model. My battery drains in 3 days.

 

A few days back some one posted specs on battery drain current when every thing is off. Search the article and compare with yours.

Note as the car battery nears end of life, it exhibits discharge in a day or two. That may be a factor as well. Depending on the enivironment, operating condition and quality of battery this period can be 2 yrs. 3 yrs is a bonus.
