Good advices Charlie, thanks, I knew the car was fairly old so I did ask and tell the cuustomer I had to remove the battery, and she said she knew it was okey because it had been done before. So I did proceed with her consent.
On another note, it's not customary to give tips here, however I did get a tip today, my first ever tip!

I ate well at lunch...
