Have been using standard batteries for almost 3 years. I currently have 3 (1-White & 2-Blacks) they are all standard size/auto. I have had the white batt for almost 2 yrs with no issue. Both of my black batts, less than a yr old, the paint is chipping off and ends up plugging the charger end and filling up the small holes along the threads. This makes it difficult to drag and I'm constantly having to clean the charger well. Anyone else having an issue with chipping paint.
