Hi to everyone, hope you all put in some fun miles this summer. The battery in my 09SEUC lasted for 4 years. It just got replaced. Now I am going to put a new battery in my 95 Heritage.( it is 4 years old) Both are always on Battery Tender Plus units when I am not riding. Just for kicks I looked in my 09 service manual under battery replacement and maintaince and I found an interesting chart. See attachement. So what this means that if you buy a new battery that may have been sitting on the shelf for 2 months or so you should always check the voltage and charge it accordingly before installation. I used to ask the parts guy if I should throw a charge on a battery when I got a new one and the answer was always the same. "No need it is ready to go" So I will be checking all batteries from now on to make sure they are at 100% charge before installation. I think it may add a little life to them.Just something I wanted to pass along. CAHDBIKER
