If you go to your favourite search engine and search for the term "halfords battery unserviceable warranty", you’ll likely find many threads on various forums from people who have experienced the same problem as me.
A few weeks ago, my car battery, which I bought from Halfords with a 3 year guarantee stopped holding a charge. I would get in the car in the morning and it would not have enough power to start the engine. So I took it back for replacement under the guarantee. The people in the store tested it, and the test machine said the battery was 'unserviceable'.
However, according to the staff at Halfords, this means that the battery had failed for some reason which is "not covered by the guarantee". I could not understand how the battery can fail to hold a charge after normal use and not come under the guarantee. What seemed worse to me, was that they were happy to solve the problem by selling me an identical battery.
That just didn't feel right to me.
But... I felt like I didn't have much choice, so under protest I paid for the new battery, even though I thought that
it should have been done under the guarantee. But I decided to take this up with Halfords by sending an e-mail to their
customer services department when I got home.
An e-mail discussion followed for about two weeks. At first they held their position saying that the fault with the battery was not covered by the guarantee. However, I started pointing out that under the Sale Of Goods Act it would be reasonable for me to expect the battery to last for 3 years, since the battery has "Maintenance Free Battery 3 Year Guarantee" written on the side in big letters:
In the end, whilst Halfords stuck to their guns and even suggested that something may be wrong with the electrics in my car, they decided to refund the cost of the replacement battery anyway. Personally, I don't have any reason to think there is anything wrong with the car. It's a well maintained Honda and everything seems to be fine. But Halfords did indeed send me a cheque for the full price of the battery - so fair play to them. I didn't end up out of pocket.
So if you have a similar problem, then complian to customer services and don't give up. A few e-mails to Halfords customer services may get you your money back. When writing to them, be nice, but firm... and persistent. It may come out in your favor, just for the effort of writing a few e-mails.
