Good Day…just finished installing my battery on my 1999 VT1100C Shadow.  The battery terminal extensions were a God send!    After connecting and re-checking clearance, I put the key in and was blown away by the power of the battery!  I have never heard that engine spun to life that fast by any battery I have bought in the past. I have to tell you I was skeptical when I lifted the battery out of the box and practically flung it across the room because it was so light.  I was thinking..no way….so far it is impressive….and riding season is upon us in Cali., the real test…I like putting new technology to the test…will let you know!!
