I just purchased the battery link and am using it with my blower. I have both the 2.5 and the 5.0 amp batteries. When I used the large one, the battery shuts down after about 25 seconds (using my blower) which normally means the battery needs to be charged. Yet when I put it in the rapid charger, it shows fully charged. I used this battery in the blower a few days ago before I got the battery link and had no problems. I did try using the smaller battery with the battery link and had no problems. Anyone have a suggestion about what is wrong?
