VW POLO 6R 2009 Car Battery Draining
Posted: Wed May 31, 2023 10:56 pm
Hello,
I have a problem with my car battery draining overnight. I've replaced my car battery due to same problem ( car not being able to start when not driving for a couple of days ) with Exide Premium 53ah, and after several months , same thing happened again. I checked my car battery, and it was around 11.7 V. Then I charged my car battery fully , and it was 12.72V when I installed it back. The next day it went to 12.44 volts, I drove for around 20 minutes and the next day it showed 12.42V. The following day ( day after I rode ) it went to 12.30V. I've been to several car electricians, and they say everything is fine, that there isn't any parasitic draw. I find it very unlikely, there is no way a healthy battery will discharge so much overnight. I've seen several people complaining about the same thing, but I still haven't found the solution. The multimedia isn't stock, the previous owner installed something similar to this ( https://www.lloydmotorgroup.com/Vehicle ... TMuWNA.jpg ) , could that perhaps be the cause? Also, I have noticed that my car lighter isn't working at all, could that be the culprit? Unfortunately, I don't have a good multimeter to meassure AMP's. I was thinking about pulling the multimedia and the lighter fuse, and then check if the voltage will drop significally overnight, but I am not sure if that would even work? The pervious owner did not have the problem, because he was driving 60km's a day, and I only do short trips few times a week. This is my third car battery in a span of few years, and I really don't think the solution is to drive a car in circles, just so the battery won't drain after a few days. Alternator has been tested and it works fine, the battery also holds charge when not connected to the car.
Any solutions, tips would be appreciated. I am not an expert, but that car behaviour doesn't seem normal to me.
Thanks!
