Yes, the stock Yuasa battery kicks ass.
Mine is still original from '06, 60k miles, drained to DEAD many times due to my stupidity, I don't keep it on a charger in the winter, and it's left outside in the great Canadian winter. As long as I haven't left the lights on, it'll start every single time. Starts just fine after the winter every season so far.
Heck, it's outlasted the battery in my car.
If it dies tomorrow, I'll buy another with a smile on my face
