reconditioning li-ion batteries

[mfreeck]

I've done a little googling on how to recondition li-ion batteries, and not come up with anything decent. Does anyone know how possible/difficult this is? A place I volunteer for has a bunch of batteries that have been sitting around for at least several months, and are of course dead. Some of these even have the chargers with them. Ideas?

step 1. place batteries in/on charger.
step 2. wait

lion batteries are designed to have little memory and a slow fade. reconditioning or electric flushing is primarily designed for nicad or nickel/metal hydride bbatteries. if they don't work after a 24 hour charge, than they're probably dead. there's a couple things you could do, but none that work worth mentioning...
