Bingo. Don't expect to get close to 10 year life with a new Yuasa.+3 or whatever on the 10yo lifespan! You could put a multimeter across the battery terminals and measure while starting the bike. The voltage under load should be ~10V or greater. A warning sign is your clock resetting to 12:00 every time you start the bike.
At 10yr just replacing on GP isn't a bad idea. Just don't expect to get close to that with this new Yuasa.
Been dealt with before, but the new replacement Yuasa batteries don't compare to the OEM Yuasa batteries that came on your motorcycle.
