ck our batterystuff.com. ive got 2 of their lithium batterys. one in my '09 tri Glide for 3 years. 5 lbs. free shipping. some have 550 CCA. for winter storeage they recommend you put them in the ice box & charge them every 6 months.
ive got a scorpion lithium for the BMW, as battery goes under tank.
I don't know, I went through a series of several batteries from Auto Zone. They had no indication of what battery company made them and every one of them failed within a few days to a few weeks, one time leaving me stranded on a national forest road. Nothing wrong with my bike's charging system either. Checked it myself following all the instructions in the shop manual then had it checked by a professional to be sure I hadn't missed something. Spent the money for the Harley battery (even though I'm NOT one to recommend Harley branded stuff) and haven't had a problem since. That was 2 or 3 years ago.
