Battery largely as advertised

One piece missing from the instructions was there is a screw that the battery is mounted on in the 2013 S. Because the battery is a bit smaller, the tech said the screw didn't mount quite the same. Additionally the carrying clip needed to be removed to attach the fuses to the battery. Docked a star for the missing steps.

The battery is much lighter as advertised.

The only other issue that's come up is the car seems slower to "wake up". I used to be able to hop in and immediately put it in reverse and drive away as it would boot up when the door handles extended. Now the computer in the driver side dash doesn't seem to boot until I am sitting in the driver seat for 20 seconds or so. This may be related to the new computer that was installed recently not the battery, so I haven't docked a second star.

Nice option for the stock battery

Installation went almost seamlessly. The only problem was the battery was slightly smaller than the stock battery so the strap didn't hold it tightly. I used the silicon carrying strap as filler and am happy with the results. Once installed I had no more "Low voltage" issues with the car.
