If no, yer fine.

Even I forgot my own advice, let a battery go five years in the SE, now I need a seatbelt module. I've posted elsewhere here about that evening in 2016, where a weak battery failed me.
The way most retail batteries are made these days I would not trust any over 30 months. You are doing well if you can get through a winter at 36 months. You can pay more like Optima, but they do not give you much either; Check their warranty.
