The moral of the story is to change it yourself.
I once took my old MGB battery to Kennings to get it checked with the intention of buying a new one if needed. I knew the counter staff very well - I was there a lot.
The counter man brought the tester and was within an inch of connecting, when he said " That's not one of our batteries"
"I know" I said "I want it testing and if its gone I'll buy a new one"............
"I can't test it if its not our battery"
I went elsewhere for my new battery......................
Kennings didn't survive.
