Are there any courier companies willing to carry "hazmat" labelled packages?

Royal Mail and Hermes state no batteries, Amazon won't pick the item up, (I thought they did collections?) and I'd like to get it back to them for a refund. It's a pair of wireless earbuds. Amazon being completely unhelpful and recommended I use Hermes

If anyone can help me out here I'd be eternally grateful.

I thought batteries that were completely enclosed were fine with R-Mail. I've posted things with internal batteries, recently (Satnav, toys).

They are fine with RM and parcelforce. You just put the battery label on the package.

Amazon have also picked them up for me. You might have to ask customer service rather than the returns centre.

As long as they are contained in the device, (ie device is unbroken) you should be able to send them via Royal Mail.

Just make sure there is no charge left in them, tape up contact points where they charge and on/off switches before boxing them up.

Problem is with lithium batteries I think

Thanks all! The help pages on RM and Hermes both state no batteries so I thought I was going to have terrible trouble finding a carrier.

Royal mail seem to suggest they since the batteries are connected to the device it will be ok?
