Battery Capacity loss is something that has been discussed in a variety of posts in this forum. Here is an article by a BMW Active-E owner who has driven 44,000 miles and so far is experiencing about 8% capacity loss. Since capacity loss is not linear, and is based on a host of factors, there is no predicting what this means for the future of his battery. However, it has good information.
