It is nice to have a recovery system available to get these batteries back in place but it does not answer the question regarding the quality of recent 680 batteries vs the older 680 batteries.
My first 680 lasted three years and I replaced it due to IFR and EI system concerns. It was still cranking the engine well. It was still running strong and still operates in my seldom used rotor-tiller. The replacement 680 started to get tired in the first year and I struggled with it for another year until replacement with a new unit last fall. This new battery, while better then the one it replaced is still not as good as the original 680. I have not really treated the batteries very differently and I regularly fly about 100 hours per year.
I wonder why there is this quality difference?
