I was going to list some Ni-Cd power tool batteries on eBay but, checking on Hermes website, they have a confused page suggesting that they both do and don't accept them.
A diagram, showing batteries as being unacceptable, refers to a full list of exclusions which doesn't mention batteries:
I know I could contact them and ask the seventeen year old Indian lad what his best guess is but, in the real world, what is the potential (or fictitious) risk to life and limb involved with sending Ni-Cd power tool batteries via courier?
Can they just be listed as drill spares? I presume stuff that's not heading overseas isn't routinely X-rayed.
