I wish batteries in my vehicles lasted that long ![Smiley :)](http://zggtr.org/Smileys/default/smiley.gif)
Perhaps my current one will, since I started using a Battery Tender Jr. on it whenever it is not being used.
OMG, I absolutely ruined it by posting the above.
COLD today. Drove to RIC, spent day there, it sat for 9 hours and was an average of 35F outside. Went to start bike to go home at 8pm and 32F and it sounded weak and almost didn't start. YUASA YTX14-BS, $60, installed 04-18-2014 and never sits overnight without being on the intelligent trickle charger when parked.
Now I get to be nervous about it not being reliable in the cold, or just buy another. 4.5 years doesn't seem long, especially when THIS one has NEVER been allowed to get low/discharged. My original only lasted 3 years, but it was never on a trickle charger and had been allowed to die (discharge completely), by accident, at least twice, maybe three times.
