Video shows a battery charging and all cells boiling(bubbling), but no heat.
This battery was ruined by not unhooking it while car was parked for six months.
After that, I put a conventional charge on it for a week. That did nothing after many cycles, or attempts.
Then I put it on Tesla cold electricity, electrical potential not moving electrons, for three days and cold ether radiant electricity restored the battery. http://www.r-charger.com
