Other than the very well known voltage permanent drop... in your expert opinion guys: -- What are the top signs that will tell you beyond any shadow of a doubt... that the battery module in question is beyond being recoverable by any device (professional or else) on the market?? There are so many opinions on the subject... false or misleading advertisement on Balancers/ Chargers... that it is needed a collective list of items coming from truly professional hands-on experienced people that have not a bias opinion on the matter. I would really appreciate your comments on this guys Posted via the PriusChat mobile app.
