Well, Installing the lightweight Braille battery is fairly easy. The product being 15 pounds is outstanding. One thing that I didn't like about this product is that the life of the battery is very short. I ran it through 1 winter and that was it. I was very impressed how it was able to start my car in 8 degrees F. I didnt even have the battery a year and it started going bad. Great Battery, Short life.
First purchase lasted 14 months. I would recommend that if you purchase this battery, that you save the OEM. Braille replaced battery under warranty, but be aware that YOU are responsible for freight both ways.
I installed this battery into my daily driver mazda mx-6. The stock battery had long needing replacement and I searched the Internet and found these had really good reviews. When I received the battery I was shocked how little it was! The mounting bracket took a minute to figure out but once it was adjusted for the battery it mounted right were my factory battery was with the hooks provided. Overall I saved about 16 pounds which is awesome. The auto posts included were a nice touch and evrything seemed thought out pretty well. I would recommend using locktite or something on the top bolts just to make sure the terminals do not vibrate loose. Can't believe this battery saved as much weight as my carbon fiber hood that was $500...
Installed just in time for the last snap of winter and started right up in 27 degree weather! We will see how this does during the summer.
