Should you take the mechanic's advice when they tell you your battery needs to be replaced?
Last time I got the car serviced they told me that they tested it and it was below the level they recommend for replacement.
I agreed to get a new one put in but I had a vague feeling that I had fallen for some kind of scam.
I don't think they faked the numbers but maybe they recommend they be replaced too soon?
I think I could have got another year out of that battery with minimal risk.
