Excellent service, battery was well packaged and came next day, I would certainly use them again. I bought this for my 1975 Triumph Trident T160

i have to say, that from start to finish, this company we’re excellent! The customer service was second to none... good communication and super fast, well packed delivery. My previous battery would still work the lights etc, but had lost sufficient power to turn the engine over. The one I chose from Tayna was the Westco platinum. I didn’t understand what CCA was until I looked it up... cold crank amps, basically, the power to turn the engine over. The other batteries I have used have around 200-220. This little monster has 320... and the difference is amazing! Very pleased indeed. Thank you. And it came with the screws etc and was super easy to fit...
