Cordless hedge trimmer (Avonmouth BS11)

Cordless Hedge Trimmer from either Lidl or Aldi, I cannot remember which.
I went to use this the other day, only to realise that you need a battery unit. I don't have a battery unit.
Perhaps you have one. It says on the side that it is compatible with all tools in the "Parkside X 12V team"
Never been used.
