Went to go for a breakfast ride this morning, hit the starter button and "click". Here are the particulars: 2012 Tri-Glide bought used, dealer installed a new battery as part of their trade-in servicing (according to service department invoice they gave me). It has been 2 1/2 years now since we bought the trike. We ride it all year long and if it sits for a few weeks (due to extreme heat or freezing cold) I have it on a battery tender. Volt meter shows a little over 14V at cruise speed. Last ride was Sunday and when we got home and stopped it restarted no problem to put it in the garage. No hint of impending doom - caught me by surprise only 2 days after our previous ride. Now, all my previous Harleys have easily gone 5 years on a battery (including 2 EFI bikes) so my question is how long have you gone on a battery in your trikes? Is there something particular about trikes that are hard on batteries or just my dumb luck to get a battery that failed early?
