The OEM battery on my 2017 Roadster gave me almost six years (40K miles) of trouble-free service. (I did periodically add distilled water to the cells, as needed.)
Notably, every time I've had the car serviced (at Nissan, Firestone, whatever) they have told me I needed a new battery..starting about year 2.
Last week the car finally cranked slow, and I figured a battery this old doesn't owe me anything, so I replaced it. But the lesson here is, I think, don't trust the shops that try to sell you batteries! Wait until you see some evidence of a worn battery.
