every two weeks my gfs car battery completly discharges. A quick look and you see the battery is dirty as all hell.

Step #1 Battery clean up with warm water and baking soda.

I want to remove the connectors for better cleaning but im afraid of losing the 12volt memory and resseting the car.

Question: Can i plug my cars positive battery to her positive connectors and my negative to her chassis so i can remove her battery?

Once clean i will hookup my motomaster battery charger

This item claims it can detect faulty battery. Not sure if it takes into consideration for parasitic drops or alternator fault.

Any tips for furthur troubleshooting?
