Mine at one-year started to do the slow-crank/hesitant stuff. Got worse once it heated up and often had to hit the starter button a few times. I finally caved in and bought the PCM680MJ.
No problems since the new battery. I got mine from a local car battery shop for about $120. Cranks like lightening struck it now. :clap:
I had an old R1100RT bought in 1996. Installed 3 normal batteries in it (BMW's and a Yuasa). Last one was the same PC680 (without the metal jacket as it wouldn't fit in that one) and it still was going strong after 5 years when I traded it on the GT.
It gets really hot where I live, often 105+ degrees. I suspect it just kills the batteries around here and sitting on top of, or behind as on the RT, engine just doesn't help with regards to their life expectancy.
Even after the BMW dealer tried to kill it when they direct wired the Autocom to it and it drained it down in three weeks. They blamed me for NOT keeping the bike on a trickle charge.
It recharged and has been fine.
