Posting a battery

I am looking at buying a second hand battery for a diy set up.
As its a lithium ion battery and postage couriers get nervous with these. Is there a courier in the uk that will take them for a uk to uk service?

Both dpd and ups have lithium battery shipping, and since it’s not air freight you should be able to ship. Different offices have different understanding of the rules and options so you might need to try a few though.
