I got the 11 pound Braille last year. It has been a good battery, but I will say that you cannot leave the car on without the engine running (like I did for five minutes at the post office so that my wife could have the heated seats on + daytime running lights were on too). We had to push the car to start.
In the summers, it isn't bad, but in the winters, it can strain sometimes to crank, but never failed to do so other than the one example above. I am happy with the battery, and would buy it again knowing what I do today. I saved about 35 pounds, and have a whole lot of space where the battery was.
