Suggesting the replacement of the battery of that age is not constructive, if it does not prove to be the cause of the problem are you willing to reimburse the man for the waste of money.
A battery could fail after one day, never the less get a battery load tested before replacing it.
A load test is swell, but the way batteries are made these days I personally wouldn't trust one over two years in my car if I were having starting problems. I think low output on batteries is a major contributing cause to module failures on our cars and Mercedes in general. I just was shopping for a new battery and couldn't find much beyond a three year warranted. I have also seen loaded tested batteries fail shortly after reinstallation. To keep things simple when searching for a repair it makes sense to me to have a good battery.
If the battery was under two years I would load test it.
