I found a lost and forgotten lithium battery to my Ryobi cordless drill that looks like the attached photo.
It has zero volts and the smart charger won't charge it and it blinks the error lights.
I've been wondering, if I could just get a little current into to the battery, perhaps the smart charger will take it from there, and I can get some use out of it.
I recognize it will likely have diminished capacity. but hey, if it works for a time to drive a few screws while my others are charging, I am cool with that.
How do we resurrect a completely drained lithium ion battery? is there a trick? Can I use my bench PSU to push some juice into it?
