Awfull company. I dealt with director. Please note reviews are for delivery! You will only know about Tayna Batteries poor goods and service when a faulty battery affects your car. This for a year or more while your trying to sort out my car electronics issue. Tayna admitted their battery that was faulty I had all sorts of problems including breakdowns. They eventually replaced it after test proved it was faulty. But, they REFUSED to restart my warranty. Others on Amazon, Ebay and Direct offer to restart warranty and are often cheaper. Dodgy batteries affect all sorts of electronics on todays computer driven cars. Always stick you bill to the battery as soon as it arrives. Poor show Tayna Directors! Never again Danny
