Yes. Ours turns 7 years old in June. The car has a little over 52k miles on it.
But I have to say that I've pampered the battery since I discovered how low its normal voltage was after about 2 years of ownership. At that time, it typically lived at about 12.25V when resting and would drop down to about 12.0 V when a load was placed on it. After desulfation and lots of pampering, it works like new now. But I've never had to add water since it never gets overcharged.
I expect to get many more years from this battery.

Yeah, seven years is about what I seem to get out of batteries in my ICEVs.
