I just had a cheap xtreme battery go bad, that was my 919 battery. died after 11 months, replaced for free under their 1 year warranty.
Yesterday I went to fire up my GSX-R and it wouldn't go, 12.x volts not under load, 3 volts once the fuel pump primed.
Yuasa battery, roughly 11 months of use. Hopefully motorcycle super store is willing to work with me on it since it was a dry battery with the acid on the side, I bought it because my GSX-R battery had some age on it, I left the new battery on the shelf for a year before adding the acid and putting it to use. So the battery is about 2 years old, just under 1 year with acid.
I just don't get it. My factory Yuasa lasted 6 years, my 919 battery lasted 2 years with me and maybe 1-2 years with the old owner.
Last year when I replaced both batteries I told myself I was going to do it right and hook up a battery tender to them. I swap the tender back and forth from the bikes, depending on what I'm riding and if Im not able to ride I would switch it maybe weekly.
Bad battery tender? bad batteries 2? really bad luck?
I've always neglected my batteries in the past with great resluts, now that I'm trying to be good with them, they have failed.
