FYI, I have been developing new auto battery repair & re-rating tech via an innovation grant for 3 years now. Potential PhD ready science. IPO has approved patent-ablity already.
I can't post details on an open forum so contact me directly at
protofabtt@gmail.com. For now, I still process/rejuvenate batteries for free as part of my R&D. Eventually the portable systems will go public.
