I had the same problem with a craftsmen leaf blower. I just took a battery from my drill and 2 5inch pieces of wire and jumped the battery for like 15 seconds and then put it on the charger and it worked perfectly
Take a charged drill battery and to wires and put positive to positive and negative to negative for just a few seconds to give it a little juice, then see if lights up on the charger
Not a problem. Simply take a functioning charged battery and wire the terminals in parallel to the "bad" battery for around 2-5 minutes. This should charge the "bad" battery enough to enable charger to recognize the battery.
Why you put that title like you are posting footage from a live show you're at? This is just you recording the Pompeii concert on your projector screen. Nm. You title all your videos that way. But still though. You're a strange cat but I ain't mad at ya.
