I needed to replace the battery in my Bonanza. This was a direct in and out job so not difficult. The best part was the very fast response I received from Spruce and UPS. I had my battery and plane back in service in 3 days! Thank you Aircraft Spruce.

I ordered this product as a replacement for my G 25 lead acid battery. I had to return it, it was not a direct replacement. It was 8 pounds heavier, and almost 2 inches longer, and would not fit on the existing battery shelf. other than that, I like the idea of it but unfortunately I was not able to use it.
