Hello all. My 2012 non turbo countryman every month or so need to be jumped. Been to the dealer, charging systems checks out, Had a AGM battery installed. Been to other shops and all checks out. But still every month or so needs to be jumped. Happened last time after a long drive. Any ideas? Thanks Mike...

 

If the battery is good, and the charging system checks out, the only thing I can think of is a parasitic load that isn't properly shutting down while the car is off. Short of it being obvious, such as the radio stays on or a light stays on it will be a little more difficult to see which system is still pulling current with the car off. The battery was replaced by the dealer and coded properly? I had found that it wasn't as simple as just replacing the battery at an auto parts store with our Mini's.....

 

in all my years of car ownership, the first question i'd ask you is: what kind of aftermarket alarm do you have?

Any sign of atlernator belt slippage?
