Long story short van battery light came on. Thought I'd check in Halfords as I bought the battery from there a few years back definetly under 3 years within warranty. So shop attendant tests battery 12v there but the Amps were quite a bit lower. So I then point out saying well it's definetly within the three years. And point out it says on the battery Halfords. He then says he has to ask his boss. Comes back says no! I then say ok can I spk to the gaffer, the attendant seems a bit shady as I have no doubt that this has happend before. I ask the manager and explain that I have no receipt paid cash and this was an exchanged battery. The other one was a piece of **** too but definetly within the three years. He then says have a look online or for receipt, otherwise come back week end. Bit confused why weekend makes a difference!! I then asked surely there is a date on the battery and he said no they have nothing to link it to. Check on the net and apparently they have date codes. Any thought on my next step lol. Surely they are selling these batteries under false pretences as a car battery these days can last up to ten years. So they must be *****.
