I bought this battery on 7 October 2021. For a long time I have had difficulty with it losing charge when stood. I have contacted Tayna under warranty, and even though I have supplied a report from my garage stating that it is the battery that is faulty, and sent Tayna photos of the tester showing the fault; Tayna are still insisting that I must return the battery to them before they will send me a new one. This means my car will be off the road. They are not offering to cover my courier charges, and not offering to reimburse my diagnosis cost of £30. To be fair I have not yet asked for this £30. Surely they should trust a professional garage, especially when I have sent relevant photos?
