Gambling with fate by riding a bike with an 8 yr. old battery. Four years is all I would push one as it isn’t worth getting stuck miles from home out on the road when a cell goes bad or the battery finally fails in some other way.
Take care,

Well there's "gambling" and there's "overcompensating".
My original battery will be 10 years old this year and it's never failed to start my CBR on the first try.
I'll probably replace it this season just because of it's age, but replacing it every 4 years?
By that logic I would be halfway through the 4-year "life" of my THIRD battery by now.
I believe in preventative maintenance, but that's just wasteful, both monetarily and environmentally.
As it is I dispose of relatively "fresh" oil every fall when I change the oil before months of storage and I'm not particularly proud of doing that to the environment. I don't need to be adding good batteries capable of years more service to the problem. Plus with today's options of roadside assistance from AMA and even AAA now, "getting stuck miles from home" can be much less of a calamity than it used to be.
