I kept them on the trickle charger during the winter and had good results prior to now. The Battery Tender had a green light showing fully charged, but it lied. I put it on another known good battery to make sure it was not the problem, and it worked fine. The big charger confirmed that one of the batteries was just caput. I decided to swap the dual Bosch batteries out of the Targa and get a couple of replacements soon since it was laid up anyway with the passenger side wheel off.
