I'll cut to the chase. I bought 3 MA1 batteries off of Ebay (with charging hub). Only one battery was able to be charged. On the charging hub, they would blink twice green and then go solid red. No LED's would light when off the charger. Tried charging individually but no joy. Is there anything else I can do to revive them? I've watched a ton of videos but haven't found the magic elixir. Or.....are they destined for a visit with the battery coroner?
