I must be doing something wrong. The OEM battery lasted from the showroom floor in '06 til march of 2015. It was perfect, until one day, nothing.
I bought the exact same battery. This one lasted from march 2015 until about september 2017, or about 25k miles. However, I first noticed it was getting weak in spring 2017 when I was in a drivethru, and i turned off the bike to talk to my friend while we waited for food, with the light still on, for about 3 minutes. I started the bike up after getting food, parked and then we decided to eat. After about an hour, the bike cooled down (it was about 65 degrees out at that time) and my bike did not start. I had to do the ole' fashioned bump start.
From then on, I didn't leave my light on. My friend's 919 did not have an issue, it started right up after leaving it on for 5 minutes. At this point, if the battery is FULLY charged, I get about 5 seconds of cranking before its completely discharged again. If it doesn't start within those first two seconds, it no longer has enough power to start and all 5'5" of me has to sprint a 480 pound bike down the block to get it started again so I can get to school. I'm kind of getting tired of doing that. I even pull a couple of the fuses for some extra juice since I had to do the headlight solder fix.
So, my first question is, am I doing something wrong that makes my battery last only a year before it starts to die? I ride it at LEAST 5 days a week, year round. No battery tender. I do use heated gear now as it is winter, which draws about 100 watts, but I started this after the battery had already shit itself.
Secondly, what can I do to maximize the lifespan of my battery?
Third, are there any alternatives to the yausa battery? Or should I just stick with it and hope the next one does not shit out on me again.
Yeah, this sucks. I have like no money and my front tire is basically bald now too. I gotta buy a new battery, that's obvious. I just don't wanna run into problems like this in the future
