Yes. This car doesn't have all those gadgets. The Red Top AGM I
considered has ~700 CCA & 100 RC. Think I'll go simple and save some
dollars. What I see is three year warranty is the max in both cases.
Buy a CostCo premium battery and you get 3 years free replacement and
10 years (or was it 100 months) pro rata. That is pretty well standard
with brand name batteries as well.

Lower end batteries generally have 1 year free replacement and 3 or 5
year pro-rata.
