Thieves have stolen 4 of our electric fence units

[ahlam1399]

and their batteries... So, ideas to prevent them nicking the replacements? Can use old units, but they're not in use for the reason they are a bit temperamental and sometimes decide not to 'tick'. Batteries much the same. What do others do?
