I left a couple of v locks on my double charger for a couple of weeks when it wasn't plugged in and they are dead as the proverbial dodo now. No amount of charging is doing anything. I presume I have drained their very souls leaving them on the charger. Any suggestions or have I thrown $600 on the fire? I imagine I have.
@sam_rides_a_mtb@jleo thanks guys, very kind.

I've brought batteries back to life that wouldn't charge with a "refresh" function on a specialty charger.. might look to see if something exists for v-lock batts.
@Vitaliy_Kiselev Oh wow, thank you, I will try that. Would be a huge relief if it worked, will let you know how it goes.
Well, it can be charger chip or just cells protection.
One strange suggestion is to put them in the freezer (in very cold area, like -20C) and while they are cold, but without any frost or water on them try to charge.
