Recycling of ZEBRA batteries

[jur]

I have a dead ZEBRA battery (internal ISO fault) which I would now like to get rid of.
So I would like to hear about your experiences in this area. I have been told, that FZSonick accepts returned batteries, but I wonder if there are other ways available.
I will also need to handle the battery. Maybe someone has a proven design for the lifting gear he would like to share?

Thanks in advance for your input,
Jens
