I recently called a well-known breakdown assistance service for help. My car had been left with lights on which had flattened the battery. The patrolman quickly started the car with a battery booster, ran the engine for about 7/8 minutes, after which the car started/ran perfectly. He then supposedly 'tested' the battery and declared it defective. Next, he tried to sell me a new battery. I declined as my sons are in the motor trade. When my battery was properly checked it was found to be in excellent condition. Not surprising as it is only 14 months old. I am advised that no battery can be tested properly after a few minutes with the engine running. Because I would not buy a battery I am now subject to a £40 surcharge if I have to call the breakdown assistance out again for the same reason. Guess who will not be renewing his membership?
