I finally drained the TB battery, not on purpose. Left it running on a home test and forgot about it.
Anyhoo, I pluged it into the charger and the red light came on, on the charger. I figured that's a good sign as the battery was completely dead. However about 10 minutes later I had to move it to another outlet and when I plugged it back in the green light came on
. Can't be charged in 10 minutes, can it?
