Q: Battery drained every 20 days

asked by on July 28, 2016

The car has a mileage of 45,000 miles and its battery keeps getting drained completely. It happens approximately every 20 days. I went to the dealer who checked the battery and it was fine. I had it replaced however, with a new one, but it didn't solve the problem. There are no error codes. The dealer could find anything wrong as the issue happens sporadically. The starter checks out fine as well. What should I do?
