I was left stranded near 800/22 with a 5 year old Yuasa. I turned off the bike to get a better look at a construction road closure that I had not anticipated. Saw an opening and knew I could safely get through without doing harm to the site. Hopped back onto the bike, turned the key, gauges swept, thumbed the starter and heard a pop..and everything went silent. EVERYTHING. A perfectly fine battery that never gave me one indication it was about to fail just screwed me. The Voyager's battery did the same thing last year, but I have no idea how old it was. To be safe, 5 years is the farthest I will push another one. I replaced the Ducati's battery when I bought the bike and keep the old one on a trickle charger in the garage for my bailout battery.
